Due:

Today we'll be testing the relationship between plants and CO2 to determine why the plant from our original CO2 experiment had major change in CO2 levels depending on when we checked. Please open the following link for the handout to fill out as you go: Handout Here

For today's experiment your group will be given the following supplies:

6 test tubes.

Parafilm/plastic wrap to cover the tubes

A funnel

BTB solution

A plastic straw

Elodea or other water plant

4 of the test tubes will be consistent between groups. Two will be kept overnight under light, while the other two will be kept overnight in the cabinet. Your group will decide where you want to place the remaining two test tubes.
