Learners test two jars containing soil, one covered and one open, for changes in temperature. After placing the jars in the Sun, learners discover that the covered jar cools down more slowly.

Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.

In this activity (2nd on the page), learners conduct a series of tests to find out which foot is more dominant. In other words, are they right-footed or left-footed?

In this activity, learners explore how to protect their skin while applying pesticides to plants.

Fat is a very important component in our diet. It's the most efficient source of energy in our bodies, and plays an important role in the flavor of foods.

In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

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

In this activity (1st on the page), learners conduct a series of tests to find out which of their hands is more dominant. In other words, are they right-handed or left-handed?

In this activity, learners create three-dimensional shapes by making some origami models of simple boxes and containers.

This is an activity which will allow learners to gain an understanding of lemur behavior through observation and role play.

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 quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

In this activity, learners explore how nanosized structures can create brilliant color.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this activity (23rd on the page), learners conduct an experiment to examine memory and learning.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this activity, learners create a cylindrical mirror to see themselves as others see them.

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.
