In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

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 about human anatomy (page 20 of PDF), learners investigate the structure of muscles by comparing yarn and cooked meat.

In this fascinating and fun experiment, learners use chemistry to identify a mystery powder and to solve a "crime," a process similar to that used by real forensic scientists.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners test what happens when they put baking power on different frozen liquids.

In this activity, learners test different food items by timing how long it takes each liquid to slide from the top of a ramp to the bottom.

In this experiment, learners test multiple food items to see if they are an acid or base using an indicator solution created with red cabbage.
