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

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

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

In this activity, learners make water-walking critters using thin wire, and then test how many paper clips these critters can carry without sinking.

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

Learners act as engineers and design mini submarines that move in the water like real submarines.

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

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 activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

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

In this activity on page 10 of the PDF, learners develop an experiment to answer the following question: "How much water can the hydrogel in a baby diaper hold?" Use this activity to explore polymers,

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.
