Biology 12

Today we did a microscope lab on Cells.   We looked at some plant and animal cells and tried to distinguish some structures:  Cell membrane, cell wall, chloroplasts, nucleus, cytoplasm.   We also made microscope drawings and calculated the magnification of the drawing based on the diameter of the field of view.  

Chemistry 11

Today we wrote a quick question quiz on measurement and significant figure calculations.

I did some demos:  1) What happens if you get acid in your eye?   Gross right!  Wear goggles kids....
2) Some chemical and physical properties of ethanol.  

Next I gave out some notes on Scientific Method and Physical and Chemical Change and Classification of Matter.  We talked about the ways that matter can be classified.

We finished with a "Quick Non-Formal Lab"  on the density of 3 liquids.   Students collected data which will be used by the class on Monday.
