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, 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.

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.

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, 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 build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
