In this outdoor activity, learners design devices that will catch prey or gather plants.

This lesson is designed to serve as an introduction to the immune system. It can stand alone or it can lead into further studies of the immune system.

In this outdoor activity, learners turn the fun of feeding wild birds into an investigation of bird behavior.

In this activity, learners follow step-by-step instructions to build a gel electrophoresis chamber using inexpensive materials from local hardware and electronic stores.

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

In this activity, learners discover that the Moon, like Earth, is made up of layers of different materials. Learners work in teams to make models of the interiors of the Moon and Earth.

In this health, cooking, and math activity, learners explore nutrition and examine nutrition labels.

In this activity, learners use household materials to investigate and explore their ability to smell an odor.

In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

In this activity, learners conduct tests for proteins, glucose, and starch.

In a series of three experiments, learners explore the basics of biotechnology using self-locking plastic baggies. Each experiment demonstrates a phenomenon or principle of biotechnology.
