In this activity, learners investigate the movement of water into and out of a polymer. Learners test the diffusion of water through gummy bears, which are made of sugar and gelatin (a polymer).

In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

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

April showers bring May flowers, but what do coastal storms bring?

In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!

In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this activity (on page 2 of the PDF under GPS: Sailboat Design Activity), learners will discover how the shape of an object, not just its weight, determines whether it floats or sinks.

Learners initially test to see how many drops of liquid (water, rubbing alcohol, and vegetable oil) can fit on a penny.

In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.

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 lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

This lesson focuses on how materials behave differently as their surface area increases.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.
