Beer's Law and Anesthesia
What this does?
To do this lab, you'll need a laptop with logger pro intsalled, a colorimeter by Vernier, small square vials, green food coloring, water, and a teacher for help and to make sure things don't get out of hand.
What to do
Have the teacher fill up small glasses with water and add food coloring with each BUT add different amount of green drops for each and there should be 8 glasses with 0% food coloring to 10%, 20%, 30%, 40%, 50%, 100%, and a glass named Aunt Elda (I don't know why its named Aunt Elda).
