In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

This multi-part activity from the National Parks Service blends the science of plate tectonics with the culture and history of places with dramatic geologic landscapes.
