In this activity about electricity and magnetism, learners examine what happens when a magnet exerts a force on a current-carrying wire.

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

This activity is a sensory experience that recreates the sounds of a pond at night.

In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

From the Weather Watchers featured theme on the CYBERCHASE website. Learners will conduct experiments to discover how air temperature and humidity work together to make condensation, dew, and fog.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

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.

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

Learners work in pairs to create three simple types of bridges, a beam bridge, an arch bridge, and a suspension bridge.

This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated.

In this physics activity, learners construct a small-scale version of a classic carnival game.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

In this activity, learners explore the different heating properties of soil and water.

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

In this activity, learners use simple materials and basic tools to construct a special toy to explore pendulums. As the head of the toy bobs one way, the eyeballs bob the other way.

In this activity about afterimages, learners explore what happens when receptor cells called cones in your eye's retina get tired.
