Buoyancy

Students observe a demonstration of how pressure and temperature affects cloud formation.

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...

In this sixth of seven activities revolving around the concept of density, physical science fans figure out if anything can be done to change the density of an object. Demonstrate by placing a can of regular and a can of diet soda into a...

First in a two-part lesson on the greenhouse effect, this lesson involves a classroom demonstration of the phenomenon, and a lab group experiment with color and absorption. Although there are easier ways to demonstrate the greenhouse...

Demonstrate the movement of lithospheric plates due to convection in Earth's mantle. Learners then model the movements that occur along plate boundaries using colored clay. 

Students perform experiments measuring water pressure. They record their observations after poking holes in plastic bottles filled with water with the lids on and then off. They discover the role gravity plays in the water flow.

Students design a simple boat and predict how much weight it can carry. They should also discover why objects float or sink and how this can be determined experimentally. A great lesson on buoyancy!

Students write and explain why an object sinks or floats.  In this buoyancy lesson students demonstrate how items float or sink and graph the results. 

Sixth graders experiment to understand the ocean's currents.  In this ocean current lesson, 6th graders complete an experiment with two bottles of water and an index card to discover information about the ocean current. ...

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...
