In this chemistry challenge, learners identify an unknown white powder by comparing it with common household powders.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

This exercise is designed to teach young learners the different parts of a plant (root, stems, leaves, flowers, fruit, and seeds), the basic functions of each part, and to show that tiny microscopic o

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

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

In this activity, learners create a biosphere in a baggie.

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