We eventually varied the volume of KI to observe the volume of bread that changed color due to the KI. Rather than partying with calculus, we used a cross section of each chunk as a determinant.deoxyribonucleicacid wrote:So how did you go about doing that experiment with the bread and potassium iodide?samlan16 wrote:1.

2. Hmm... my coach once gave me a bottle of potassium iodide, a slice of bread, a cracker, and a plate for an experiment. The experiment was only difficult because it was hard to quantify.
