In this activity, learners use found natural materials to create a water haven for bees and other insects.

The Watershed Connection
Source Institutions
In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.

Soil Density
Source Institutions
In this activity, learners will test soil content using their sample, some water and a container that seals.

Dinosaur Homes
Source Institutions
In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.
