Happy Holidays!

Everyone should be complete the take home test over break. There are lots of resources at the bottom of the blog, and there is a balancing equations simulator, which can be found below under 'Phet Simulations'.

This video will also help you with balancing equations:

Thursday, December 13

All Sections: Complete the worksheet you got in class today.

**Start doing your background research for your science fair project!!

Wednesday, December 12

All Sections: A background research outline and an experimental for your science fair project are due next Tuesday (12/18). If you did not get a check plus on your science fair proposal, or if you just have questions for me, you should make an appointment to see me. Sign up sheets for these appointments for the next two days can be on the door of 4K3.

Sections 8 & 10: The terms from last night's homework, plus the terms below are all of the words/phrases you need to complete your covalent bonding map. Define, in your notebook, any term below that you do not already have. Then, use your full list to complete the concept map. Do this is pencil just in case you make a mistake!

• polar bond
• non-polar bond
• s orbital
• p orbital
• hybrid orbital
• sigma bond
• pi bond
• double and triple bonds
• shapes of compounds
• linear
• bent
• trigonal planar
• trigonal pyramidal
• tetrahedral

Tuesday, December 11

Section 9 & 10: Use chapter 6 (section 5) of your textbook to define the following words/concepts in your notebook; you will need them for tomorrow's in-class activity:
