In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

This activity (located on page 3 of the PDF under GPS: Glaciers Activity) is a full inquiry investigation into the forces of gravity and air pressure.

In this activity (page 1 of the PDF under SciGirls Activity: Water Slides), learners will whip up some suds with a cup of water and a tablespoon of dish soap until the bubbles are stiff enough to star

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

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.

Electrolysis is the breakdown of water into hydrogen and oxygen. This Exploratorium activity allows learners to visualize the process with an acid-based indicator.

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 water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

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

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.

In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.
