Plasticity of Leaves Lab

Due Date - Monday, September 18th

We are going to be doing this very interesting lab now, while trees still have mature leaves on them. Please read the background information and procedure for this lab by clicking HERE.

Sometime before Thursday, September 14th, collect 10 "shade" leaves and 10 "sun" leaves. Store them in a plastic bag so they don't dry out (why is this important?). Bring in your leaves for weighing on an electronic balance on 9-14-06. You will also be doing your area measurements at that time; feel free to jump ahead and do your area measurements at home.

Here are a few links to help you prepare the Introduction part of your report: http://www.ex.ac.uk/~sawatlin/graduation/celandine_project.htm
