Experimental Design B/C

[samlan16]

So what is the hardest topic you've ever seen in Experimental Design (more specifically Divison B but Divison C helps)? My team struggles with Experimental Design.

1. Division C actually helps- ExpD is the now pretty much the same event for both divisions except for significant figures.
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.

So how did you go about doing that experiment with the bread and potassium iodide?

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.
