In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

In this chemistry challenge, learners combine acids and bases in a universal indicator to create five different colors.

In this activity, learners design, build and test wind turbines. Learners go through the design process and use the scientific method to test important blade variables.

Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

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.
