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

In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what th

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

In this activity, learners build water-propelled engines from soft drink cans.

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.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

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

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

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

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

In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.

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 quick SciGirls activity (page 1 of the PDF under SciGirls Activity: Doghouse Design), learners will be introduced to the concept of thermal conductivity.

In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.

Learners make their own paper. They start by shredding old newspaper, clean toilet paper, and clean paper towels.

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

Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

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.
