This kit gives students the tools they need to estimate the diameter of one molecule of oleic acid using indirect measurement.
First, they model the experiment using ball bearings, using a known volume to make a flat "pancake" and then finding its thickness. Then a single drop of oleic acid solution is placed on a water surface, allowing students to estimate the diameter.
Kit includes oleic acid solution, chalk, 12 droppers, bb's, and complete instructions. Enough for 8-12 student groups to repeat the experiment dozens of times.
The Molecular Size and Mass Kit can not be shipped outside the continental United States.
