In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

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

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 conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

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

Learners observe and compare the sizes of three toy “growing” crocodiles made from water-absorbent polymers. One is it its original state, dry, hard, and about 10cm long.

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

This activity (located on page 3 of the PDF under GPS: Alligator Habitat Activity) is a full inquiry investigation into organisms and the health of their ecosystems.

Learners observe a sealed test tube containing a small amount of solid stearic acid.

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, learners design a device to solve a problem: how to get a ball out of a drain pipe.

In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

This is written as a display, but can easily be adapted to a hands-on activity. Learners observe and shake containers of shiny liquids.

Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

This is an activity (on page 2 of the PDF under Bone Regrowth Activity) about the two main components of bone - collagen and minerals (like calcium) - and how they each contribute to its flexibility a

In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.
