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

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

In this water activity, learners explore how water drops behave on different surfaces.

In this activity (located on page 3 of the PDF), learners investigate the way water moves and how we can control and direct water.

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

Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.

Learners investigate how the temperature of water affects its density.

In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.

An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.

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 water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

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

What causes frost to form on the outside of a cold container? In this activity, learners discover that liquid water can change states and freeze to become ice.

Learners model the ocean currents that carry hot water from the tropics to northern latitudes.

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.

This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.
