Ups and Downs of Diving

Change where an object floats in water. Pupils experiment with a Cartesian diver by squeezing on the side of a plastic bottle. Learners pay attention to the bulb of the pipette as the bottle is squeezed to determine what is happening...

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...

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...

Third graders complete an experiment to introduce them to the concept of water pressure. In this water pressure lesson plan, 3rd graders create pressure in a water bottle and observe the force of water that is created.

Dive into an exploration of the water cycle cycle with this simple earth science lesson. After first discussing where rain comes from, young scientists define the terms condensation, evaporation, transpiration,...

Pique interest in water pressure, demonstrate buoyancy, and explore water displacement concepts with a homemade Cartesian diver. You may want to change the name of the toy, however, as is is not documented the Rene Descartes...

Blow your class away with a gust of humor as they watch this video about air pressure and wind. Along the way, they find that the density of air (as determined by temperature, altitude, and water vapor content) leads to air pressure...

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...

Sometimes the simplest experiments leave the biggest impression! Introduce young chemists to the Cartesian Diver by having them make one of their own. Use the Diver to further their study of liquids and gases, as well as compression.
