Static electricty Demo
2. Mr Hoegh getting shocked.
1. Moves the electrons!
2. My favorite part was Mr. Hoegh laughing after many times of getting shocked! And when he was trying to turn it off! :)
1.The atoms move the electrons and it shocks you kind of like a lightning bolt.
2.Mr. Hoeghs face face when he knew he was going to get shocked.
Hydrogen gas is made because the reactants of HCI, zinc, and manganese mix together become hydrogen gas.
The reason they don't use hydrogen gas in blimps is because it is flammable and will destroy the blimp when lit on fire.(Hindenburg)
My favorite part was mr.hoegh kept touching the coil thing and shocked himself
2. Hydrogen is flammable so the blimp would start on fire so people could die.
Atoms are made up of negatively and positively charged parts. Static electricity is produced by electrons trying to escape. The part I liked best was when Mr. Hoegh kept getting shocked and also when the light bulb lit up.
Static electricity
1. It shocked you every time you touched it to take some electrons from all of them that they were losing.
2.When he put the light build on the machine.
Hydrogen balloon
1. It was a chemical reaction from the zinc and the hydrochloric acid touching.
2.They could catch on fire and take lives like the one lab we did.
Dry ice
1.Dry ice is something that is really cold and could give you frost bite in a few seconds.
2.When we put the soap in the warm water and dry ice to get the soap with the ice smoke.
Hydrogen gas is made when you mix hydrogen chloride and metal. The mixture makes hydrogen gas that was collected in a balloon. When the balloon was tied a match was lit and the gas in the balloon was burned. The balloon melted.
STATIC ELECTRICITY DEMO
It's messing with the atoms making ions even. it shows the electrons moving from one to the other. I liked the electrostatic generator, because of how it ran and how it reacted with the object... And Mr. Hoegh.
HYDROGEN BALLOON DEMO
The mixture of the zinc, hydrochloric acid, and magnesium made hydrogen. They don't use hydrogen in blimps now days because hydrogen is flammable and just like Hindenburg with just a spark can start on fire. I liked how the mixture blew up the balloon.
DRY ICE DEMO
Dry ice is frozen Co2 or carbon dioxide. It has to do with Science because carbon dioxide is a gas .The dry ice with the warm water and the dish soap in the test tube and how it bubble but the bubbles were full of Co2
Static electricty demo
2. Mr. Hough getting shocked
Hydrogen Balloon Demo
1. The chemicals combinding
2. Because Hydrogen is very flamable
Dry Ice Demo
2. playing with the dry ice,
Hydrogen gas is not used in blimps anymore because it is too flammable.
Wow I didn't think there was that much fun watching static electricity! That was pretty cool watching the light illuminate through your hand was Pretty cool. Haha! Balloon filled with hydrogen : failure. It started dripping as it burned to the floor. HOLY COW!! That dry ice is cold!!! Haha what fun with the film canister!
1.)It's about the positive and negative charges.
2.)When Mr.Hoegh touched it and it shocked him,went through his arm and lit up the bulb in his other hand.
1.)Because of a chemical reaction between substances.
2.)Because Hydrogen gas is flammable,so if a spark got to the gas, then it could blow up.
1.)frozen carbon dioxide; the reactions it has with other substances.
2.)I liked how in the test tube it poured out,but I like how it looks eerie in the aquarium thing with the candles. And touching it and playing ice hockey with pencils.
1.because of the positive and nagative charge
2.when Mr.Hough laughed after he would get shocked
1.a chemical reaction between the two elements
2.because it is very flamible
1.frozen cardon dioxide,it is a extreme temperature
2.putting it in the test tube and catching all the bubbles
1 it's positive and negative atoms reacting with the static electricity making sparks
2 my favorite is when Mr. Hoegh got shocked and started laughing
1 when putting zing and hydrochloric asid together you get hydrogen and that is wayyyy flammable
2 because the Hindenburg exploded to easily and killed meny
1 frozen CO2 has alit to do with science
2 the hockey puck and the bubbles
So, lets see here the first experiment thingy, consister of the silver srobe electricty thing, it conducted electricty because of the friction that was generated. The electrons flowed into the light bolb and reacted the elecrons and made it light up and also made Mr. Hoege jump. The second experiment consisted of a hydrogen gass baloon that reacted to fire and cought on fire ( so it is really flammable because it started the ground on fire).Next is the dry ice bomb.We are working with frozen (Co2) carbon dioxide.The dry ice in the water bubbles and it reacts and releases the gass.
Static electricity demo: my favorite part was when mr. Hoegh would try to turn the machine off and get a little shock and his face would turn all red. The atoms and the structures had to do with the electricity because of them releasing electrons and gaining electrons from atoms.Hydrogen balloon Demo: they do not use this type of gas anymore for blimps because it is very flammable, the chemicals are combining and producing a chemical reaction that is how hydrogen gas is produced. Dry ice demo: My favorite dry ice experiment was putting the dry ice and hot water and soap in the cylinder and when the bubbles came out and you squeezed it was just gas. The dry ice shows freezing point and melting point for certain things.
Atoms create how much they reached when the electrons transfer
My favorite part was when mr.high shocked him self
When the magnessium reacts with NFL
It is ver explosive.
Hydrogen gas is made because the reactants of HCI, zinc, and manganese mix together become hydrogen gas.
The reason they don't use hydrogen gas in blimps is because it is flammable and will destroy the blimp when lit on fire.(Hindenburg)
Dry ice Is frozen carbon dioxide. My favorite part about the dry iced was when we put it in hot water.
Static electricity Reacts with atoms by taking away it's electrons. My favorite part was when Mr. Hoegh kept on getting shocked.
Static:
1. The electrons get rubbed off with friction and are passed to the next thing because the electrons are on the outside of an atom.
2. When Mr. Hoegh got shocked a lot. And the lightbulb flashed on and Emily's hair went up high with the balloon.
Hydrogen:
1. The reaction of the zinc and the danger (HCl) creates the gas.
2. Hydrogen is flammable and the Hindenbergh was filled with it and it blew up.
Dry Ice:
1. Solid Carbon Dioxide.
2. When we got a chunk of ice and we volleyed it around.
Dry ice is solid H20 and is so cold that it can burn your skin. I liked it when the bubbles came out of the beaker.
Static Electricity
1. They have a negative charge like electrons
2. The balloon and hair stickey up thing.
Hydrogen Balloon
1. It makes a chemical reaction
2. Because its explosive
Dry Ice
1. Solid carbon dioxide. Its an element and a lab
2. Playing with it
1. The static electricity has to do with atoms because the fiction makes things have static. But not as much if there's moisture in the air.
2. My favorite demo was either when you rubbed a balloon on peoples hair and the machine thing
The static electricity has a lot to do with atoms and their structure because it makes friction and the atoms get really crazy.
The machine lighting up the light bulb was my favorite!
The positive and negative charges attract
The light one
It happens when the chemicals react
Because hydrogen is very flammable
Dry ice is solid carbon dioxide
Electrons leave one atom and go to another.When mr Hoegh couldnt turn it off without getting shocked.
Zinc combining with Magnesium. Because it is flamable.
Solid carbon. very cold. changes rapidly. The bubbleing stuff.
1.positive and negatives are attracted to each other causing static electricity.
2.My favorite part was when we got the light bulb to light up.
3. Hydrogen gas is produced becauses the chemicals react.
4. They don't uses Hydrogen gas to flaot blimps anymore because it is very flammable.
5. Dry ice is frozen carbon dioxide.
6. My favorite dry ice experiment was when we got to touch the dry ice.
The positive and negative charges are attracted to it's opposites. Thus causing static electricity. Watching joey's hair stand on end
It happens when the chemicals react
Hydrogen gas is very flamible
Frozen co2 we are finishing up on compounds and mixtures
The one where he gave us dry ice to play with
1. Electrons leave an atom, goes to another
2. Mr Hoegh getting shocked
1. Zinc/Magnesium reacting with HCl
2. Hydrogen gas is flammable, incident with Hindenburg
1. Solid CO2, Very Cold, Goes directly from a solid to a gas.
2. Playing with it on the tables, Popping the Carbon Dioxide bubbles.
Static electricity is the extra electrons created from friction, my favorite part was when Mr. Hoegh lighted the light bulb through his body.Hydrogen gass is produced from the chemical reaction of zinc and magnesium. They don't use it anymore because it is highly flamable and explosive.Because it pits out smoke and is cool. My favorite was when we got to playnwith it.
My favorite lab was the dry ice lab. It was really cool to see how dry ice affected things.
The positive and negative charges attract
The light one
It happens when the chemicals react
Because hydrogen is very flammable
Dry ice is solid carbon dioxide
satic electricity demo...
if you use balloon it takes the electrons out of your hair so that your hair has a positive charge and the balloon has a negative, then the two attract... my favorite part was when Mr. Hoegh was lighting the lights when the static machine shocked him...
Timmy waskow
1 It attracts the opposite positive/negative.
2 When the light bulb was lite up through Mr. Hoegh
1. Because of friction, one has a negative and a positive charge.
2. The machine that created the electricity.
1.The electrons switch out with the other electrons.
2. The balloons
they might want to be seprated.
2. when Mr. Heogh touched the metal ball.
they might get separated
2when mr.hoegh to the metal ball
Atoms exhange atoms with the othr element. 2 the light stick wAs my favorite
They don't use hydrogen to float blimps anymore because it is flammible.
Zacch
1) they will lose electrons and if one is positive and one is negative they will attract
2)watching static electricity shock mr. heogh
3)ts lighter than air
4)because it's flammable
because it is being melted.it makes a flame when a spark is near it.
Hydrogen gas demo...
metal and hcl combine and create a flamable gas...
because its falmable, the hindenburg is a good example why...
We mixed magneseum zinc and HCL
it's to flammable
To do with the outer level of the atom (electrons) positive and negatives at track!!!
When the machine shocked mr.hoegh. It was funny. Sorry mr hoegh!!!!!!!
Because it is lighter than air, but they don't use it because it is flammable.
Frozen carbon dioxide! Really cold. Can't touch more than half a second.
Static Electricity
1.Because of friction, electrons transfer, and when the hair has a positive charge, and the balloon has a negative charge, they attract each other and act like a magnet.
2. I liked the Electrostatic Generator and the light
Hydrogen Balloons
1.It's produced due to chemical reaction.

1) it's produced when zinc and HCL are chemically combined
2) because it is very flammable
1) dry ice is frozen carbon dioxide
1) frozen carbon dioxide
2) the hockey puck one
The electrons were positive or negative and that made them attract to each other. The electrostatic generator was cool even though it just shocked Mr. Hoegh. Also the lighting of the bulb turning on as Mr. Hoegh touched the generator was funny. Because it is lighter than air but they don't use it because it is flammable. Frozen carbon dioxide of 109 degrees. It is made up of elements. CO2
1) it happens when two stoms with a different charge rub together.
2) watching the light light up through Mr. Hoeghs body

I loved the part where it made the lightbulb light up and sometimes went throught the ballon. Hydrogen ballon was cool i mean its awsome how it blew up and people screamed too. Dry ice was cool because of the air hockey movement
1. becauseit doesnt stay high as long
2.because it can blow up if it is caught by fire
1.is frozen carbon gas, to see what elements are made up in it
2. When we got to play with it

2) watching the static electricity machine shock mr hoegh
3) when u burn metals
4) because it is flammable
5) Frozen co2 Really cold has a heavier density then air
6) When we got to use a chunk of dry ice
We mixed HCL and magnesium Calcuim
It is exPolosive
The was cooooooool.
Opposites attract
Baylee K. Per. 8
Static Electricity Q's:
1) The atoms are filled with positive and negative energy, so the atoms are reacting with the static electricity.
2) When Mr. Hoegh was holding the forecent lightbulb in one hand and touched the Vandagraph machine. And then the lightbulb lit up.
Lexi Wright. Per.8
Static Electricity:
1) The atoms are filled with positive and negative energy. So the atoms will react with each other.
2) When Mr. Hoegh put his hand up to the machine.
1. Opposites attract
2. When Mr.Hoegh kept getting shocked. It was funny.
1.
2.because hydrogen gas is flammable
1. Frozen carbon dioxide

static electricity have to do with atoms and their structures because positive and negative charges attract and negative and negative repel, as positive and positive rep also. my favorite part of this activity was when the charge went through mr h and lit the light bulb.
hydrogen gas is produced because there is a chemical reaction.
i think that they don't use hydrogen to power blimp anymore because hydrogen is flammable.
dry ice is very very cold ice. it's not normal ice.I is -109 degrees below farenheit. it I heavier density than the air around us.
