1. DIRECTIONS FOR THIS LAB: You are to work in groups of three or four students. You will dissect according to the handout. This is a documentation of your work.
As you go along, you will photograph relevant sections with the structures labeled and create a Power Point slide show by inserting your photos into this show.
You need to use your flower pins to designate specific structures. The flower pins are in 5 different colors: green, yellow, orange, white, blue. Use these colors as a key on the Power Point slide you are creating. Students must follow the colors that are assigned for each structure. GOAL: Try to identify ALL structures shown in my pics. Sometimes, due to cutting errors, it is not possible to show everything. Do your best and enjoy the learning process. Please share your finished product with
You may delete this slide when you are done!
