In this multi-part activity learners examine non-point water pollution.

Learners take on the role of environmental engineers as they design water filters.

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

In this hands-on activity, learners will construct a scuba diver that can float in order to explore how sea creatures stay neutrally buoyant in the ocean and to see what kinds of forces might be influ

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

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

Water, whether fresh or salty, serves as one of the best electrical conductors on the planet. Does salt effect its conductivity?

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

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

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

This activity offers learners and their families several ways to raise their awareness together about home water.

No glue is needed for learners of any age to become marshmallow architects or engineers.

In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

In this activity, learners discover how solar energy can be used to heat water.

In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

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 sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

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