In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

In this water activity, learners discover ways to move water across the water table.

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

In this activity (on pages 4-5), learners make fake snow by adding water to the super-absorbant chemical from diapers, sodium polyacrylate.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

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 physics activity, learners build their own rockets out of film canisters and construction paper.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.
