Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.

In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

In this activity, learners explore the concept of conducting or insulating electricity.

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

In this activity, learners make water-walking critters using thin wire, and then test how many paper clips these critters can carry without sinking.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.

In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.

In this activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.

In this weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.

In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.

In this activity, learners follow a recipe to create play dough scented with fruit-flavored drink mix.

In this activity (posted on March 20, 2011), learners follow the steps to construct a stroboscope, a device that exploits the persistence of vision to make moving objects appear slow or stationary.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

Learners use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor.

In this activity, learners test exhaled breath for carbon dioxide and learn how to use an indicator as a simple way to measure pH.

In this activity, learners create a cool floating animal using the science of magnetism. Learners discover what happens when a piece of magnetic metal enters a magnet's field.

In this activity, learners explore the process of condensation.
