In order to examine the random nature of mutations and natural selection, learners "breed" clutches of Egyptian Origami Birds (Avis papyrus) using random number generators (dice and coins) to mutate s

In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.

What is the optimal environment for hatching brine shrimp? Using a scaffold, learners design and conduct experiments testing the effect of a single abiotic factor on brine shrimp cyst hatch rate.
