In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.

In this activity, learners will examine a variety of seeds, describe them, and determine how they are dispersed.

This laboratory activity helps learners understand the concept of biological succession by simulating the process in a microenvironment with various protozoans.
