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 activity, learners explore why frost forms. They create their own frost using a solution of ice water and salt in a glass.

In this activity, learners compare water pressure at different depths. Learners discover that water pressure increases with depth.

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.

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

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

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

This is a quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

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 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, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

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

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

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.

In this activity (on pages 4-5), learners make fake snow by adding water to the super-absorbant chemical from diapers, sodium polyacrylate.

In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.

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!

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.
