In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

Did you know that you would be a different age if you lived on Mars? It's true!

In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.

Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.

In this activity, learners explore center of gravity, or balance point, of stacked blocks.

Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.

In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

In this activity, learners confront their perceptions of gravity in the solar system.

This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.

In this activity (page 2 of PDF under GPS: Glaciers Activity), learners will measure the rate at which water streams out of a leaky cup.

In this optics activity, learners explore how many objects they can see in a set of mirrors (hinged like a book) at various angles.

In this design challenge activity, learners use a balloon and other simple materials to design an air-powered rocket that can hit a distant target.
