In this activity on page 4 of the PDF, learners investigate the importance of washing their hands.

In this activity on page 4 of the PDF (Water in Our World), learners conduct some quick and easy tests to determine the differences between water and other liquids that look very similar to water.

Build a glider that uses the same physics as a curve ball, for less than a dime.

To understand how skaters turn in midair, try this little experiment! Individuals can do this activity alone, but it works better with a partner.

Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

Learners observe a tank of water containing cans of diet and regular sodas. The diet sodas float and the regular sodas sink. All the cans contain the same amount of liquid and the same amount of air.

In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.

In this activity, learners heat ice and water of the same temperature to get a hands-on look at phase changes. This is an easy and inexpensive way to introduce states of matter and thermodynamics.

Extract your DNA from your very own cells! First, learners swish salt water in their mouth to collect cheek cells and spit the water into a glass.

In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.

In this weather activity/demonstration, learners watch as a ping pong ball is suspended in a stream of air supplied by a hair dryer.

In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts.

Each group of learners uses everyday materials, such as paper, toothpicks, and tape to design and construct a structure intended to support the weight of a cinder block for 30 seconds.

In this activity, learners investigate the reflective properties of light and mirrors as they make a kaleidoscope.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners discover that they can create a lens from a water drop. Learners test their lens by looking at words or pictures.

This is an activity (located on page 3 of the PDF) about the mixture of materials in bone and how they affect its strength.

Using a milk-based recipe, learners create "moo glue" which is basically white school-type glue. The "secret ingredient" in milk that helps make glue is a chemical called casein.
