Science 10

We learned how to write formulas and name molecular compounds today.  Remember that molecular compounds are formed with covalent bonds and they are the types of compounds made when 2 non-metals share electrons.

We completed a worksheet in class and for homefun:   pg. 199 #19, 20 and 21.   Quick Question Quiz on Thursday on writing formulas and names for compounds.

Today we collected the green worksheet on different types of atoms in compounds.   Then we went over how to name ionic compounds- compounds made up of a metal + non-metal ions.    The top half of the naming worksheet should be completed as well as pg. 191 #3 b, d, f, h and j.

The second half of class we had a guest speaker, Dr. Karl Larsen.  He came to discuss his research on painted turtles.   Cool talk!  I think we all learned lots and will be on the lookout for turtles as well as Badgers and Grey Squirrels.

Bohr Models were collected.   We continued Chemistry Review by looking at molecules of compounds and how we can determine the number of each type of atom in the compound.   Green worksheet for practice is due Thursday.

Science 10

Today we reviewed drawing Bohr Models for atoms and Ions and practiced by drawing Bohr Models of the first 20 elements.   This is due next class

Science 10

Today we 1) Turned in Lab 6A pg. 162

2) Completed our notes on Isotopes, Mass Number, Protons, Neutrons and Electrons

3) Did a worksheet on Isotopes and Atoms

Worksheet should be turned in or completed for homework and due Monday.

Today we thought we would finish the Algal Growth lab, but surprise!  We have to wait until next class to weigh them.

Then we took notes on Atomic Theory.   Then we made some hydrogen gas and exploded it! 
Lab:  6A  pg. 162-163.    Do questions #a-d and #h pg. 163
