When you first heard that we would be learning about minerals, here were some of the initial comments:
- "So...... we're gonna learn about rocks....... OK......."
- "Are there really minerals in a bottle of mineral water?"
- "Diamonds, gold, and other gemstones are minerals. Can we keep the ones we work with?"
- "Aren't there minerals in the Fruity Pebbles I eat for breakfast?"
In your comment, completely answer the following questions. If you don't want your comment to be published, that is fine! Just let me know in the comment you leave.- Minerals are identified by their properties. What are some of the properties you used to distinguish one mineral from another? Why is it best to use more than just one or two of these properties?
- Did some of the properties "work" better than others? Which ones were the most effective? Which were the least effective? Explain.
- What was the most difficult part of identifying minerals?

1. I used color,hardnes, i used more than one because it descripes more of the rock im examing.
1. luster, hardness, streak, and color
2. most- luster and streak because they vary making it easier to tell which is which
least- color because it changes
3. reading the number, and knowing if it was right &the miinerals that were very similar to each other were hard to figure out
1. You can use color, harndess, streak, cleavage, luster, fracture, special propertes (metalic, nonmatalic, submatalic) those are just a few of the ways. I prefer using the streak or the special properties (metalic, nonmatalic, submatalic). Color is hard sometime because you might not know if that's the actual color of the minneral. Lots of things can change that.
2. Streak because it brings out its natural color not the fake one (if there is one).
3. Color because it could of changed.
2.I think color,hardnes,and the shape of the mineral were most usefull.I think that shinny,and the other stuff didn't really work out for me.
3.The most difficult part were anelyzing it was hard.
1!!. Streak, Luster, Color, Cleavage, Density, Fracture, and other Special Properties. Using 2 or more properties is better than just using one because every mineral is different, so it has different special qualities that only it has.
2!!. Some properties do work better than others. If you are using streak instead of color, it classifies it better for its natural appearence.
3!!. The most difficult part was when they did not have a number.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :D
1. Some of the properties you use to destinguish minerals are: color, luster, streak, special properties (ex. flouresence, taste, radioactivity), cleavage and fracture, hardness, density.
2. The properties that worked well where streak, and luster. The properties that are most effective where streak, special properties, and luster worked well. Color is one of the properties that didn't really work because the color of a mineral is often disrupted by water, air and other imperities.
3. The most difficult part of identifying minerals was probably seeing how hard the mineral was because we didn't know what the hardness of the object we were trying to scratch the mineral with.
1 I used the streak and hardness to find which mineral is which.
2 The hardness and streak one worked the best and just the color didnt work that well at all.
3 Telling if it was matalic or not.
1)Luster,Streak,Color,Hardness,
Cleavege and Fracture, and Special properties.
2)I think that a property that works is the hardness because we had a key to identify the hardness of a finger nail and copper. I think that the least effective was color because many minerals had the same color, but when it came with the different properties, they were very different.
3)I think that the most difficult part of identifying minerals is if it is meatilc, nonmetalic, and submetalic. For me it's hard to see if the mineral has luster.
1. Color, luster, streak, hardness, cleavage, fracture, density, and special properties. You should use more than one property to identify a mineral so you don't get them mixed up.
2. Identifying the streak worked the best since color could change because of water, air, or impurities. Hardness was one of the most effective and color was the least reliable.
3. It's luster was the most difficult.
1. Streak, luster, density, cleavage, fracture, hardness, color, special properties. So you can put all of them together and know for sure that it is that mineral, because a mineral could have the same color, or luster, and it could be a different mineral.
2. I would say that the ability to scrath glass (hardness) and luster really helped because a lot of the rocks were the same color but had different streaks and it helped us identify better. I would say that color, or streak were the least affective, because most of the minersls colors and streaks were mostly the same, and it was hard to tell
3. I wouls say the most difficult part of identifying minerals would be putting all of the properties together. Because some would have a color and hardness that matched up but not luster or streak and the mineral didnt match up so you had to start over.
1) Streak, Cleavage, Fracture, Color, Luster, Harderness, Density.
It is good to use more than one because many minerals may share the same color.
2) The most effective were the special properties like reactivity with hydrochloric acid or salty taste.
3)When many minerals share the same properties
1. Because the properties may be the same for many minerals so you need to be sure to use all the properties on the mineral.
2. They are all equal cuz u cant be sure on a mineral by just the color or luster or hardness you have to do all of the properties.
3. The hardness cuz it was like a story problem.
1. Color, Streak, Special Features, Hardness, Cleavage, Fracture, Density. It is best to use more than one or two because some minerals could have the same color and streak but have a different hardness. It makes it easier to identify a mineral if you know many of it's properties.
2. Hardness was the most effective and easiest way to identify a mineral because it usually unique from the minerals we looked at. Color was the least effective because lots of minerals are the same color.
3. Some of the minerals were harder to figure out because they had many different colors which made it hard to use the dichotymous key.
1. Some of the properties are: Color,Streak,Luster,Hardness,Fracture and Clevage,Density. It's better to use more than one because you can get more detailed in deciding what mineral it is.
2.Yes, Hardness and Streak were really helpful. But color wasn't the best because it can change.
3.I think the most difficult part of it was, clevage and fracture.
1) The properties used to identify a mineral are: luster, hardness, fracture/cleavage, density, color, streak, and special properties.
2)The streak, color, and the hardness were the easiest to identify a mineral by. The hardness is pretty specific, and it's really easy to see the color/streak.
3) The most difficult part of identifying a mineral was it's luster. Some of them were really easy to tell that some of them were metallic, but others were only sort of shiny.

1.cleavage, fracture, streak, luster, hardness and sometimes color. its better to use one or more so you can narrow down your choices.
2.yes some did work better like luster and streak probably worked the best. Fracture and cleavage worked the worst. Cololr was also a bad propertie to go by.
3. The most difficult part was cleavage and fracture.
1.We used streak, hardness, fracture/cleavage and sometimes color. It's better to use more than one because then you can narrow your choices down.
2.Yes, some others worked better. Color and Streak were probably the best. But color was probably the least effective because it can change in water and in the air.
3. To narrow your choices down and find out whether it was cleavage or fracture.
1. Color, streak, luster, and density, it's better to use more than a couple because you need to be 100% sure its the mineral you think it is
2. Streak, density, hardness, cleavage/fracture were better than others because they are more reliable, a lot of minerals could ahve the same color, etc.
3. Identifying it by luster/streak alone because it's hard to tell what mineral is what by using those two
1. Some properties that we used to identify some minerals are color, luster, fracture/cleavage, streak, density, special propersties, and hardness. It is better to use more than one or two of those properties because you can have an accurate description on the mineral.
2. Properties like color and streak worked pretty good. Some properties that were kinda hard to figure out was luster, cleavage, and fracture. The easiest was color and the hardest was probably the luster.
3. The most difficult part of identifying minerals was the luster. Also try to figure out if it had cleavage or fracture.
a property used is strek the color of the powder of the mineral this is more accurate then color since color is affected by air and water.Another property used is special properties since this are unique to a few.Also another one is harness so you what can be can be not scratched
2.i think streak and hardness were the best indicators of which the mineral was but cleavage fracture color and luster didnt really help but it did help somewhat
3.The most difficult part was the
color and cleavage and fracture since theycould be very misleading
1. hardness, color, streak, cleavage, fracture, special properties, luster. cause some may have the same color or luster or streak but they wont have all the same properties.
2. color was the least effective cause some minerals have the same color. the best is hardness cause most dont have the same hardness.
3. trying to tell the luster.
Drew M.
1.)Color, luster, cleavage, fracture, hardness, special properties, and streak. It is best to use more than just one or two of these, because some minerals are very similar in some properties. For instance, two minerals might have the same color, but different hardness.
2.)I think that the most effective was hardness, and the least effective was color
3.)cleavage and fracture
1. some of the properties to compare minerals are color, density, luster, clevage, fracture, some of the special properties are taste and flouresent color under purple light. Its best to use more than one because for example some minerals have the same color so if you wanted to find a mineral you can't always use one property.
2. the most effective of the properties I think are either density or hardness. The least affective I think are color or luster. Because sometimes two minerals are the same color and sometimes you don't always know if a mineral has luster or not. it is sometimes hard to tell. The most difficult part to identifying a mineral is probably the hardness or luster. or maybe clevage or fracture I get those mixed up some times.
1. We used luster, color, special triats, hardness, shape, streak, clevage, fracture. You want to use more than one because some minerals may have the same traits.
2. Luster, streak, and their scratch were the best. Color was the least effective.
3. Telling if one of them had cleavage or fracture.
1. some of the properties that you can use to distinguish one mineral from another are streak, luster, color, cleavage and then there are special properties like magnetism, flourescence, and acidic properties. in order to make sure that you have the correct mineral, you may want to check more than one property, expecially if one of those properties is color, since color can change depending on if it was exposed to water or air. this is one of the least effective ways of indentifying because it can change easily. a more effective way is streak. streak is the color of the mineral in powdered form, and can be found when mineral is rubbed against a streak plate. this is an easier way of identifying a mineral. the most difficult part is when you find two mineral's that are similar, they may look similar, but really are two completely different minerals.
1. Streak, Luster, Color, Hardness, Cleavage, and Fracture. Because some minerals can have some of the same properties.
2. Yes, they even have a moh scale to tell the hardness of each mineral. The color is the least effective way to find a mineral because it can be effected by many things.
3. Trying to identify either cleavage of fracture.
1. I used color, streck, hardness, luster, fracture, cleavage, taste, magnetisum, reactivity, and the ablitly to glow under a certain light.
2. I think hardness, luster, streak, and the way it breaks works the best. Least effective was probably color.
3. The most difficult part was trying to deturmine weither the break was fracture or cleavage.
1. you can tell minerals apart by there color, streak, luster, fracture/cleavage fracture or hardness. you can also tell by its special properties like how reactive it is, if its magnetic, and its florencenes.
2. the properties that worked better than others were the hardness, and the color streak becuase thats the two most unique properties. the outside color was the worst way to idenetify minnerals.
3. i think the most difficult part for identifying minnerals is that some of the properties are the same. and they look alot like so the only way you could tell which minneral was which you had to figure it out by the special properties.
1. color, streak, luster, magnetism, density, reacts with acid, flouresence, cleavage, fracture, nonmetallic, metallic
2. Streak works better than color because color can change very easy when the mineral reacts with air, water, etc.
3. I think that density was the hardest part of identifying minerals...well it actually wasn't the hardest, it just took the longest to figure out.
1. Minerals can be identified through a number of properties. Some of these are density, luster, hardness, color, streak, and special properties such as flourescense, radioactivity, and taste.
2. Some of the properties were much more useful than the others in identifying the mineral. For example, harness was very useful as few minerals share the same hardness, so even with a mildly innacurate hardness test you could narrow it down to a few options. However, some properties such as color were not very useful in identifying the mineral as many minerals share the same color and you may not get an accurate color reading because a minerals color can be affected by impurities.
3.In my opinion, the most difficult part of identifying minerals was deciding if a mineral had cleavage or fracture because we did not have the materails to break the minerals and even if a break was found it was hard to identify if the breaks were smooth.
1. you can use, luster, streak, hardnss, density, cleavage, fracture, special properties, and color. :) because some of them might have some of the same properties.
2.yes.. but not really.color worked well. but all of them have something very useful to use.
they are all affective because some of the minerals have different properties.
there really isnt a most or least effective one to me.
3. i think it wasnt that hard. :) good teacher you are. :)
1. color, streak, luster, density, cleavage, fracture, hardness, and special properties. using more than one helps give more factors to make it easier to identify the mineral.
2. streak, density, and cleavage are very reliable since color and luster can be affected by impurities, pressure, or just smudges of other substances on it.
3. sometimes it was hard to tell if a streak was light or dark.
1. Some of the properties that you can use to distinguish one mineral from another are:
- color
- luster
- density
- hardness
- fracture/cleavatge
- streak
- and special properties.
It is best to use more than just one, because you can't really know for sure what mineral you are observing by only knowing one of the properties, because many minerals have similar properties.
2. I think that the streak worked better than others, because you knew what the actual color of the mineral was. It was just in powder form. The propertie that was the most effective was probably streak and special properties, because most of the minerals have different special properties, that make it easier to figure out which mineral it is. The least effective property was luster, because it was hard to tell if it was metallic or nonmetallic.
3. I think that the most difficult part of identifying minerals was the hardness.. because it got confusing.. this scratches this, but cannot be scratched by.. ya know what im saying?? ya.. it was confusing.
-Anna
1. You use color, density, hardness, luster, cleavage, fracture, special properties, and.... one that I mayhaps have forgotten..... hmmmmm. Its best to use 2 or more because then you can be more positive about your answer in identifying the mineral.
2. I think streak, hardness, and special properties were the best, mainly because they are constant (unless the hardness of a mineral changes by water.. or heat...?) Worst I think is color because it can be effected by heat, water, and air..?
3.I think the hardest part was classifying the luster or hardness because ones that weren't supposed to scratch strangely did scratch at times.. so yeahh. hah
anyways. human density lab featuring Tyler Beck is gonna be funnnyyyyyyy(:::::::::::::::: ha this is great..!
1
.Density,hardness,streak,fracter,sp-ecial properties,cleavege,luster.
Because some other minerals have the same properties of other mineral like the color can be the same as other minerals
2.I think hardness and density was the ones that worked the most.And they were the most effective to finding the minearal.And I think fracter and cleavege were the least effective because they were hard to tell apart,and hardness and density were the most effective because you could get the answers and they were easy to tell them and get them.
3.when the mineral looked the same and was hard to tell them apart and to tell what the color was.
1. luster, streak, color, hardness, density. Because some minerals might have the same color or same hardness. So you should test more properties to get more detailed info.
2. streak and hardness were the most effective because they dont change. Color was the least effective because it can change.
3. Some minerals have the same properties.
1. Density, streak, color, special properties, luster, cleavage, fracture, and hardness. A lot of minerals have close to the same properties, so you don't want to just use one property.
2. Hardness, density, and streak worked best because they differ a lot in minerals, so they are easy to tell apart.
3. Some minerals have a lot of same properties so they are very hard to tell apart.
1-Hardness,Cleavage/Fracture,Luster,
Color,Special Properties.
So you can figure it out better.
2- Yes, Hardness and i think color were more effective.Least effective was probably like luster and cleavage/fracture.
Luster didn't work because you can't tell very well and same with color.
3- Finding the hardness and luster. And like color.And cleavage/fracture.
1.I used the color of it, the streak color and the acid and hardness.It is best to use more than one because if the color was wrong and the streak was right than you can still get it right.I used luster too!
2. Yes like the streak helped out the most to me to get the answers right.Streak was most effective and color was least effectiver.
3.If you did something wrong then you have to start all over and get it right and sometimes you think your right and you really are not right.
1. Streak, fracture & cleaveage, luster, color, hardness,density special properties
2. Streak works best, a lot better than color, because color can be decieving and change because of impurities making it appear to be a different mineral while the streak is always the same
3. probably determining them from just one property, it helped when you had many to compare from.
1. streak,hardness,luster,density, special properties, cleavage,fracture, and color
2. Streak and hardness were propably the most effective becuz those dont change because of anything like color does.
3. when some minerals look almost exactly alike....like pyrite and calcopyrite (i think thats how you spell it)
1.by their streak, color, special properties like megnetism, hardness, and luster. It is best to use 2 or more because some minerals hve the same harness but different streak or have the same special properties but different luster.
2. Hardness and streak were the best because they all very between differnt minerals. i think color was the least effective because the minerals may have had the same color but different hardnesses or they may look alike so color was the least.
3.figuring out if they had this certain thing or if it is different and othere things.
1. Luster, streak , color , density, special properties, cleavage, fracture, and hardness. A lot of minerals look the same but there is special properties that differ the minerals between each other.
2. Hardness, Density, and streak. there are some minerals that look the same but when you measure there hardness density or look at their streak there will be a difference if it is not the same mineral.
3. minerals have a lot of different properties and some times you have to use all of them to find out what mineral you have.
1. Some of the properties are by the color of the minerals streak,luster,uv light,color,fracture or cleavage,hardness,and shape
2. Yes some of the other properties worked better than others like the streak worked altot better and luster,sometimes the color, or if the mineral was hard enough to stratch glass.
3. The most difficult part of idenitify mineral was probably by the color becasue each mineral can be the same mineral but different color and straching the glass becasue it was hard to tell if it stracthed the glass or not.
1 Streak, color, luster, density,special properies, Hardness, cleavage/fracture. Because some minerals have some of the same properties but not all of them.
2 Yes Density, streak, and luster.
Color because color can change when other things happen to the mineral to change the colors
3 Finding the density
1. steak, color, luster, hardness, density, special properties, fracture.
2. Hardness and density are good ones because if one minearl can scratch something and the other one cant and they look alike there not the same. color is one of the least effictive because two minearls look the same.
3. finding the denisty.
1. color streak cleavige fracture special properties, because some things might be efected by impurities
2.yes some properties do work better than others the streak was the most efective and color was least efective
3.I thought the hardest way to identify miniral was cleavige and fracturebecause they are hard to tell apart
1. Colors,cleavage,fracture,hardness shape,luster,streak,special properties.Two because so you can more identify the minreal.
2. Yes some of the properties worked better like the streak and some of the color would work so you know wich one it was. The least effective i think was the luster and the cleavage.
3. Telling the fracture.
:)
khi.
yeah so i'm gonna start answering these questions now. so here i go . .
1- minerals are identified by alot of things. some examples are streak, color, hardness, luster, magnetic, special properties, flouresents, clevage/fracture.
:)
number 2: the color didn't work out very well because sometimes stuff can effect that. the hardness helped alot because it can't change. its always the same hardness. another thing that helps is using a u-v light. i don't know if i spelt that right but okay . ha.
number three: the most difficult part is trying to identify the color because it can sometimes be between two colors. or it can seem like it has specles of colros. (if you don't know what that means it means where there are a bunch of different colors on one stubstance.)
:) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) :) <--- you said it was okay to do smiley faces (:
ha ok i'll go then cause tyler is gonna find out his density! woohoo can't wait.
enerta is a property of matter (:
scciiiennce ruulless.
okkkkkbye (:
Hey Hoegh(:
1.Minerals are identified by looking at their color, streak, luster, cleavage/frature, hardness, magneticness special properties and some other things. You should use more than one or two of these properies because some minerals might have some of the same properties.
2.Color can be changed by some diferent things so that isn't the best way to determine a mineral. The streak is more relilable then the color.
3.The most difficult part of identifying minerals was probably trying to identify the minerals that had a lot in common. Also the color was hard because some minerals are different colors than what they usually are.
kbyee!
oh, p.s. You are still cool(:
no wait, the coolestt!! 8) <-- cool smiley face!
okay, bye. Make it a great day or not, the choice is yours!!
1. Used luster, streak, color, special properties, hardness, cleavage, fracture, density. It's best to use more than 1 or 2 properties in case 1 is incorrect.
2. luster, streak, density, and special properties worked best. cleavage, fracture, and color aren't always the best because you don't know if a mineral has cleavage or fracture and color can be changed by different things.
3. Looking at the color if 2 minerals could be the same in everything else.
1. Some properties you use to identifly minerals are their streak, hardness, fracture, cleivage color, luster ect. you should use more than one property to identify a mineral beacuse impurities can change the color of the mineral and some properties of two different minerals can be similar.
2. Color is not a very good property to depend on for identifying minerals because impurities can change it. A good property to use to identify a mineral is streak.
3. The hardest part of identifying a mineral is being acurate.
1. some examples of properties used to distinguish one mineral from another might be luster, color, fracture or clevage,hardness, density, streak,and special properties such as magnetism and how it might look under a floesent light. It would be best to use more than just one or two properties because some minerals may have a couple properties in common.
2.they density and hardness because they vairy more between different minerals. i think color might be one of the least effective ways because the color can change and alot of minerals are all the same color.
3. i don't think any of them were difficult but the density was the most time consuming.
thanks for reading....!
bye now(:
It is better to use more than one properties because minerals can share properties.
2.yes because color of you mineral can be the same as many other mineral.when density of one mineral is diffreint than other minerals. I think density is the best becase it is unike to that mineral.color because a lot of mineral have the same color.
3. It was that a lot of the minerals have the same properties.
1. Color luster density fracture cleavage
1. To make sure you are identifying it correctly
2. Color is the worst because it can change from things like water and impurities most effective was the probably the streak because it is much different through other minerals. If it reacts with acid or not because it is a for sure thing.
3. Making sure you have the right one. If you had one repeated, you had to do another over again.
1.color luster density cleavege fracture, you cant just use one becuase some minerals might have the same color or another one of these characteristics
2.color was least effective becuase a lot of minerals were the same color, the most effective was streak or hardness becuase not every mineral has common streaks or hardnesses
3.finding out what minerals each one was
1. Color luster density fracture cleavage
1. To make sure you are identifying it correctly
2. Color is the worst because it can change from things like water and impurities most effective was the probably the streak because it is much different through other minerals. If it reacts with acid or not because it is a for sure thing.
3. Making sure you have the right one. If you had one repeated, you had to do another over again.
1.Some properties of the minerals are luster, streak, color, hardness, cleavage, fracture, and special properties. It's best to use more than one property because some minerals may have the same color, and streak.(others too.)
2.Yes, the streak and hardness because even though two minerals may have the same color, they're streak and hardness could differ from water and impurities.
3.The color because some minerals have a numerous amount of colors.
1. Some properties of minerals are luster, color, streak, hardness, cleavage, fracture, and special properties. Its best to use more than one property because a lot of minerals have some of the same properties.
2.Yes, streak and hardness were the most effective and color was least effective because the mineral could have been changed by water or impurities.
3.Deciding what color it was, because most of the minerals had many colors in it. Also identifying the luster, whether it was metallic or nonmetallic, was a little difficult.
-->IsabelS(:
1.) Some of the properties you use to distinguish one mineral from another are: Color, Metealic, Non-Metallic, Fracture, Cleavage, Size, Shape, Reaction to acid, Streak, Speacial Properties, Hardness. It is important to use more than one way beacause usually theres more than one mineral that has at least one of the characteristic the same as another one.
2. The streak and the metalic and non metalic are are some ways to figures it out. The color was the least effective because alot of minerals looks the same.
3. The most difficult part of identifying minerals was trying to figure out the name in general because alot of minerals are pretty close to the samee.(:
3. I think the most difficult part of identifying minerals is telling whether the mineral has a metallic luster or not.
1. Some properties i used to distinguise minerals was streak, hardness, and metallic luster. It is best to use more than one or two because many minerals have the same properties.
2. The ones that were the most effective was the metallic luster because that narrowed it down really quickly. The one that was the least effective was clevage and fracture because we were not able to break the mineral to see if it was one or the other.
1. Properties to identify minerals include streak, luster, color, hardness, cleavage/fracture, and special properties. It is better to use more than one property when identifying a mineral because some minerals may have been exposed to the same weather and many minerals are similar.
2. Streak and color i think worked better than hardness and luster. I think the least effective property was color because alot of the minerals have similar color.
3. I think identifying the color was the hardest to do because alot of the minerals had alot of different colors and alot of the minerals were similar.
1.) There are many properties. Some, called "special properties" are only for some minerals. Things such as being magnetic, or having fluorescence is having a special property. Hardness is another property. It shows how resistant that mineral is to being scratched. In order to dicede the hardness of a specific mineral, peeople use a Mohs Scale. It's better to use at least two properties because many minerals are very similar in at least one way. Using more than one is a way to specify which is which.
2.) Color is not the best property to use. Color is affected by things such as air, water, and impurities. You really can't get an accurate response using just color. Fracture and cleavage are also only an "okay" way to decide what a mineral is. Unless you do the test yourself, you cannot for certain know whether it is smooth, or rocky if it has been cut. Things such as hardness and streak work a little better. Of course, testing for special properties is the quickest way to decide what a mineral is, but unfortunatly, not all minerals have special properties.
3.)The hardest part of identifying minerals is the fact that many minerals are a like in different ways. Going back to the first question, it is important to do many tests, just to be certain that you have the right mineral.
1. Some of the properities are luster (how a surface reflects light),density (mass devieded by volume), hardness, cleavage (braking in right angles or thin sheets), fracture (breaking in chunks), special properties (things like taste and magnitism)and color . It is best to use more than one propety because there is more than one mineral that is black or has a hardness of 2. using more than one is the most acurate way to indentify minerals.
2. Yes some properties work better than others. Streak worked the best because it isnt as effected by air or water as color is. Color was probably the worst because it can be affected by inpurites and water.
3. I think that the hardest part of identifying minerals is that some minerals are very similar looking and have some of the same properties and it makes it hard to see the difference.
1. Color, streak, hardness, cleavage, fracture, luster, special properties like magnetism or flouresence. It is best because some minerals share some properties with each other like there color.
2. Yes. I thought that the hardness and special properties were most effective because only a few minerals had the same hardness and hardly any had the same special properties, and it really narrowed down the possibilities. I thought that color and cleavage/fracture were least effective because a lot of the minerals had the same color and a lot of them had the same cleavage or fracture.
3. I thought the most difficult part was trying to figure out if it had luster or not.
1-Some of the properties are the color, hardness ,streak color, clevage/fracture, luster, special properties-magnetism, flouresence, or taste.It's best to use more because then you have a better chance at guessing the right one.
2-Yes, they say that the streak is the most effective, and that the color is the least effective b/c the colors can change.
3-trying to figure out the difference between two minerals/which one they are when they have a lot of things the same, like color/streak.
1.) Some of the properties of identifying minerals are: streak,(the color of the mineral of powder form.) color,(the color can be affected by pressure and exposure to air.) density, (mass divided by volume) hardness, (how hard the mineral is on the Mohs scale.) luster (the way a mineral reflects light), cleavage (the way a mineral breaks along a smooth flat surface), fracture (the way a mineral breaks along curved surfaces, specail properties (there are many special properties). It is best to use more than one so you can be sure that you have the right mineral. Another reason is that you cant always tell by color and hardness. 2.) Some properties work better because color can be changed and some minerals have the same hardness. One property that is more effeective is streak because that can not be changed. The least effective one is color because it can be changed. 3.) The most difficult part is that sometimes two minerals or more have the same properties, or similar ones and it is hard to decide which one is which.
1. Luster, streak, hardness, color, cleavage, fracture, special properties. Special properties because some are magnetic and some are floursence.
2. Fracture, cleavage, hardness, and special properties are the most important properties, because they acan tell you what a mineral is in a little time and not take a lot of time. Luster and streak are the least effective because streaks could be the same color adn luster just tells you that light reflects off of it.
3. Identifing the luster of a mineral if you don't have a light.
1. Luster, cleavage, hardness, color, streak, metallic, special properties. It's good to use more then one of these properties because many minerals are similar in color or hardness, so you should look at it's different properties to differ it from other minerals
2. Color was not that effective because many of the minerals were similar in colors. However streak was defferent (if it had a streak) so that was a pretty effective way to identify a mineral
3.For me it was actually color, because I wasn't sure how discriptive to be and many of the minerals had similar colors
1.For some of the properties I had used: hardness, color, luster, streak. Some of the special properties were: magnetism, fluorescense, and cleavage/fracture.
2.Yes,I thought streak worked pretty well when testing metallic objects. I also thought that color had worked well when trying to figure out the first step of either the dark or light colored mineral.
3.The most difficult part in identifying minerals was when you had to identify the color of streak that the mineral had, and narrowing it down to the right mineral.
