Bohr Model Practice

Grab a markerboard and progress through this slideshow to practice drawing Bohr models.

Drawing Chlorine

Representatives of the Crazy 8 8th period show us how to draw the Bohr Model of an atom of chlorine.

Atomic History

We haven't always known what we know about atoms. Our view of what atoms are has changed a lot over time. See how much you can learn about the atomic model with the following websites and our textbook.

Defining Atom

Answer the following question in your comment below:
An atom is the smallest particle into which an element can be divided and still be that element. Now that scientists have learned that an atom is made up of even smaller particles (like protons, neutrons, and electrons), is this definition still accurate? Why or why not?

Upon the completion of this blog response, go to Ediscio and complete the "Atoms" cardbox. That way, you shall ace the standard check on Atoms.

Symbols Quiz

Be sure to get a full list of elements from Mr. Hoegh before taking this quiz. This will allow you to spell the element's name correctly. Good luck! Not that you need it if you've been playing those chemistry games.

2011 Chemistry Games

I am challenging all Crazy 8s (and other Earthlings that have access to our blog) to achieve greatness in the 3rd Annual Chem Games. Use the following links to earn (as many points possible) and learn (about the individual elements and their chemical symbols, subatomic particles, and placement on the periodic table). These websites can help reinforce your knowledge of atoms and the periodic table, concepts that we have started (and will continue) to learn about during our chemistry unit.

Here are the links:
Element Flash Cards (set up the game so that it tests you on the 33 elements you are supposed to know) Non-Crazy 8 visitors can view this link to find out what those elements are.
Element Math Games
Periodic Table Activities
Setting the Periodic Table
Element Matching Game
Fun Brain Periodic Table

Feel free to share your high scores, along with the game and its conditions, in the comments section of this post. Post your scores with honesty and integrity. As always, these are virtues required of Crazy 8s and others that visit our blog. Gold medals in the 2011 Chem Games are at stake! Good luck!

Periodic Table Preparation

We have a "Periodic Table" Standard Check on Thursday. I'd like you to know the difference between a period and a group, the characteristics of metals, nonmetals, and metalloids and where to find them, and the names of the groups and where they are found. The info from everyone's "Grouping the Elements" Prezis should be helpful. Here are some other things that might help you prepare:

1. Periodic Table Ediscio Flash Cards: Mark all of these cards for learning at Ediscio.


2. Do the sample standard check embedded below.

Grouping the Elements Project

Day Two: Research uses for the elements in your element group and start your Prezi.

1. Go on the internet and do a search for some or all of the elements in your group.
2. List 4 everyday uses for at least 5 of the elements in your group.

Here is a list of websites that you may choose to use:

Web Elements: Click on the element from your group that you want to research. This will take you to a page that provides essential information on the element. Read this. Scroll down the page and you will find the "Uses" link. This page should have the info you need.

3. You should get a start to your group's Prezi. Be sure to include the following:

• Title
  
• At least 5 Characteristics
• Simile/Metaphor
• Everyday Uses
• ***don't just limit yourself to the above things. If you find something really cool and can find a way to include it in your presentation, do it. Help us learn about your group.
  

If you are nearing the completion of your Prezi, see if there's anything else that can make dynamic and creative. Be sure to set the path, and develop a plan with your group for how you will present.
