In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.

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

Learners make a refrigerator that works without electricity. The pot-in-pot refrigerator works by evaporation: a layer of sand is placed between two terra cotta pots and thoroughly soaked with water.

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

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

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

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

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

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

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.

This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.

As a group, learners consider sources of water pollution to understand where pollution starts and where it ends up.
