Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this physics activity, learners conduct two experiments to explore free-falling.

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.

Learners analyze mixtures of dyes using filter paper chromatography. They place spots of the different dyes at the bottom of a piece of filter paper, and hang the paper to touch the surface of water.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

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

In this activity, learners will use simple materials to explore centripetal force and variables by swinging a cup of water without having the water spill out.

In this activity, learners use sieves with different-sized holes to sort balls by size.

In this activity, learners explore why humans sweat. Learners compare the effects of heat on a balloon filled with air and a balloon filled water.

This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.

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.

In this activity, learners use open inquiry to learn about the process of science as well as gain experience regarding the Law of Conservation of Mass, dissolution, and density.

This activity has learners observe water and compare it to other liquids.

This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this activity, learners build water-propelled engines from soft drink cans.

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

In this activity, learners will explore the density of an object in water. Learners will compare what happens to fruits and vegetables in regular and salt water.

In this activity, learners capture and observe planaria, which are worms that eat tiny pond critters.
