Additional Details
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.
Products being sold are not toys. They are for Educational / Laboratory use only. They are not for use by children 12 and under.
