Science 8

 Today we looked at microscopes and how to find the actual size of organisms. 

Homework: Read page 6-11 do reading check page 11

Biology 11

Today we looked at HOW evolution happens by studying Darwin's theory of evolution by means of natural selection.  We took some notes and then read a case study on the peppered moth.  Questions on the peppered moth as well as your paragraphs on the PBS video series are due tomorrow.

Today you should have turned in the worksheet on Evidence for Evolution. 

Science 8

Today we practiced designing experiments and writing hypotheses by working in groups of three and designing experiments to answer questions.  We aren't really going to do these experiments, it is just for practice!

Next we stayed with our groups and labelled some microscopes and looked at the parts and functions of some compound light microscopes.  You have two worksheets to complete on the parts and functions. 

Science 9

Today we practiced how to determine the number of protons, netrons and electrons in a atom of any element.   Remember that # protons = Atomic #.

Next we looked how to draw Bohr Models showing electrons in their different shells. 
Homework: Read page 220-222 Do #1-4 on page 223. 

Science 8

Today we wrote our safety quiz and then spent the whole rest of the class doing an experiment where we looked at the effect of changing one variable on the dissolving rate of an alka seltzer tablet.   Great job working in the lab for the first time. 

Science 9

Today we wrote our safety quiz and then started our Chemistry Unit with a short power point on Atomic Theory.   Notes were filled in and the worksheet was started on.......but not for homework. 

Biology 11

Today we looked at Evidence for Evolutionary theory:
1) We got some power point notes on direct and indirect evidence for evolution.
2) In first block we did a LARGE workbook assignment on Evidence for Evolution (due Monday)
3) In second block we started a video assignment  PBS video series on Evolution (due Tuesday)
