DESCRIPTION
The history of teeth cleaning agents stretches back thousands of years. However, toothpaste as we know it today is a pretty recent development.

The Properties of Toothpaste Kit from Innovating Science has enough materials for 5 groups. Teacher’s Manual and Student Study Guide copymasters are included.
You provide distilled water, metric rulers, test tube rack, balance, and beakers or plastic cups.
