In this activity, learners get a closer look at the shape of a drop of water and a drop of oil. Learners first drip water onto wax paper and examine the shape of separate drops from a side view.

In this activity, learners investigate the behavior of magnets. Learners create a "wonder wand" with a magnet so they can move a skater around.

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.

Learners place multiple M&M's in a plate of water to watch what happens as the candies dissolve.

In this activity about gravity (page eight of the pdf), learners will very simply explore how gravity affects objects using balls and toys.

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.

Young learners investigate and observe the properties of three liquids -- water, vegetable oil, and corn syrup. They use their senses to collect data and ask and answer questions.

In this activity, learners will explore how the voice works and feel the vibrations produced by vocal cords.

In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

In this physics activity (page 8 of the PDF), learners will explore the property of density.

In this activity, learners investigate whether more people are squares or rectangles. People with similarly sized heights and arm spans are classified as squares.

In this engineering activity, challenge learners to invent a water filter that cleans dirty water.

In this activity, learners experiment with the density of ice, water, and oil. Learners will discover that the density of a liquid determines whether it will float above or sink below another liquid.

Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon.

Learners place an M&M candy in water and observe what happens. The sugar-and-color coating dissolves and spreads out in a circular pattern around the M&M.

Learners investigate signs of a chemical reaction when they mix vinegar and baking soda. In addition to a gas being produced, learners also notice the temperature decreases.

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

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.

In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.
