Sticklers
Source Institutions
In this outdoor simulation game, learners search for pretend animals called "sticklers" to determine and map where they live (habitat) and how spread out they are in that area (distribution).

In this activity, learners discuss how life is defined and conduct a simple experiment, looking for signs of life in three different “soil” samples.

Sensory Hi-Lo Hunt
Source Institutions
In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

Trees: Recorders of Climate Change
Source Institutions
In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

The Great Fossil Find
Source Institutions
On an imaginary fossil hunt, learners "find" (remove from envelope) paper "fossils" of some unknown creature, only a few at a time.
