The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

In this physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both weights fall

In this activity, learners use ABS pipe and an air leaf blower to make a strong shooting machine.

This laboratory activity helps learners understand the concept of biological succession by simulating the process in a microenvironment with various protozoans.

In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.

In this activity, learners explore accuracy and precision.

In this physics crime lab or demonstration, learners pretend they are criminologists and must find the "muzzle velocity" (speed of the bullet as it leaves the gun) of a gun used to commit a crime.

By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.

In this experiment, learners use JOY liquid detergent and glycerin to make the largest bubble they can that lasts 15 seconds.

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.
