In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.

Discover how the salt in soil affects plant growth with a few seeds, some cotton, and salt. In this hands-on activity, you will plant seeds in 2 different kinds of soil, containing more or less salt.

In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this activity, learners perform an experiment to find out what determines a flower's color.
