In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.

In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

In this activity, learners will imagine the challenges and opportunities of asteroid mining.

Los jugadores toman turnos para añadir figuras de tres cuadrados a la cuadrícula. Intenten encajar sus figuras en la cuadrícula de modo que bloquee al otro jugador.

In this activity, learners explore ray optics. Learners discover that they can use a magnifying glass to create an upside-down image.

In this activity, learners will keep track of how much they can do in one minute. Instructors can pick something everyone will do for a minute, such as jumping up and down or drawing stars.

In this activity, learners plant seeds and watch them sprout and grow inside a CD case.

In this activity, learners keep track of how much paper the group uses in a week. Build awareness of paper waste, while strengthening measurement and estimation skills.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this activity, learners use information gathered from a variety of sources to design and make their own insect.

In this outdoor activity, learners will gather natural materials outside that they think a dinosaur would want to lay its eggs in.

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.

Combine math and exercise with this activity. Learners count how many times in a row they can skip rope or throw and catch a ball.

In this activity, learners will test soil content using their sample, some water and a container that seals.

In this activity, learners will experiment with changing flower colors. Learners will investigate the effects of acids and bases on flower colors.

In this activity, learners craft their own model of a comet on a stick to make it fly around the room.

In this activity, learners will observe laminar and turbulent flow of water using only a plastic bottle, liquid hand soap, food coloring and water.

In this activity, learners will explore the physics of liquids and gas by playing with both! Learners of any age use their own breath to move drops of water across a smooth wax paper surface.

This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.
