Source Institutions
Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

Gaming in the Outdoors
Source Institutions
In this set of outdoor games, learners increase their awareness of the outdoor environment by going on a scavenger hunt and an out-of-place hunt.

Plenty on the Plains
Source Institutions
In this activity, learners compare the ways of life of Plains Native Americans who hunted and moved frequently to follow the buffalo herds, and Native Americans who farmed and lived in more permanent

Vortex
Source Institutions
In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.
