Science 8

Today we did our Chemistry Unit test.  Done Chemistry!!   and we took some of our silver home in a mini test tube.   Too bad it's only worth $1.

Next we worked on our Element Superheros.   Finally we took notes on Static Electricy.  Homework:  Read page 274-277.  Do #1-4 page 278. 

Science 8

Today we wrote the test on the immune system.    Next we threw our osmosis eggs off the balcony!

For classwork (and homework if you don't get it done):  Read page 246-249.   Do Reading Check on page 249. 

Science 9

Today we did a mini lab to practice chemistry.   We got some silver out of our reaction!

Next we turned in our review questions and all the text book questions....Yes there were a lot of them! 

Answers to some of the Practice Test:  Modified True/False 1)F (8 electrons max)   2)F (lost electrons)    3)F (alkali metals)    4)T     5)F (Halogen Family)    6)F ammonium chlorite    7)T

Biology 11

Today we set up our bacterial plates to test different antibiotics on two different bacterial cultures.   Then we worked on our microbiology projects---due Friday AT THE LATEST!!   Found HERE

Due Wednesday:  The Diversity and Biology of Monerans.  (Worksheet from last class). 

Science 9

Today we worked on our review for the Chemistry Unit test coming up on Wednesday.   Here is a great online practice for naming and formula writing for ionic compounds.  Make sure you click on IONIC compounds.

We also played an exciting game of jeopardy.  Found HERE.

Chemistry Unit Review handout and textbook questions due on Tuesday.
