In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this outdoor, freshwater activity, learners explore the behavior and food preferences of crawdads (or crabs) by "fishing" for them with various baits.

This exercise is designed to teach young learners the different parts of a plant (root, stems, leaves, flowers, fruit, and seeds), the basic functions of each part, and to show that tiny microscopic o

Learners and their families celebrate and recognize the importance of making healthy choices every day by participating in a health fair.
