Molecular Size and Mass Kit
Use indirect measurement to find the diameter of a single molecule! First, students model the process using ball bearings, then repeat the experiment using oleic acid floating on water. Enough supplies for dozens of repetitions.

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.
