Through three activities, first-time physical scientists wonder at the properties of water. Freeze some soda cans and a container of water prior to the investigation to show that water expands when frozen. Lab groups experiement with...

Playing with balloons, water, oil, and bottles help put this lesson over the top! Participants use air-filled balloons in water tanks to experience gas compression. They also use oil-filled bottles to experiment with buoyancy. Included...

How do we clean up oil spills and other pollutants in the water? Explore water treatment strategies with a set of environmental science experiments. Groups remove oil from water, work with wastewater treatment, and perform a water...
