Biology 12

Today we finished off the nervous system by looking at dissected sheep brains and labeling the parts.   Next we looked at the male reproductive system and labelled a diagram with parts and function.  This diagram is due tomorrow.    We watched "The great sperm race"

Biology 12

Today we finished off the Brain Worksheet and Completed a Nervous System Review Handout.

These were due at the end of class today.

Also given out:  Exam study guide and practice exam.
