Water Pressure Experiments

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...

Explore the world's water without leaving the classroom! In this second of three uncomplicated but wonderful activities, physical science learners feel the pressure of water. They discover that the deeper the water, the stronger the...

Thorough instructions are given to guide you through making a demonstration hydraulic pump from two plastic soda bottles. After using the resource to teach your class about Pascal's and Bernoulli's principles, turn them loose in groups...

Physical science learners conduct a simple experiment using the heat of their hands to affect the fluid pressure. They place a balloon atop a freezing cold bottle and observe what occurs as it warms up. Both activities demonstrate how...

Give young scientists a new appreciation of fresh, clean drinking water. After learning about the ways astronauts recycle their air and water, your class will work in small groups creating and testing their very own water...

Here is one of the better Spangler episodes. Two young girls perform an experiment that results in the creation of a lava lamp! Water, oil, Alka Seltzer, and food coloring are combined in test tubes to create this effect. There is a lot...

This simulation begins with an exploration of water pressure and atmospheric pressure. In the flow portion, scholars reshape a pipe and see fluid dynamics at work. The water tower portion encourages pupils to determine how water...

Learn to make a very impressive cloud form in a plastic bottle! By pumping air into an empty plastic bottle and quickly releasing the pressure, we can cool off the air and force the water to condense into a thick cloud. It's a very...

Water pollution is everywhere, and pollutants range from oil to fertilizers. Bring the concept to life by demonstrating the difficulties in getting particular pollutants out of water.

Here is one of the better Spangler episodes. Two young girls perform an experiment that results in the creation of a lava lamp! Water, oil, Alka Seltzer, and food coloring are combined in test tubes to create this effect. There is a lot...
