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.

Change the density of water by adding minerals. The presentation discusses density—from the definition to calculations—and applies it to the real world. It briefly mentions specific gravity, and finishes by showing Archimedes'...

Here's a lesson that is simply a-MAZE-ing! Introduce science scholars to pipeline systems through a hands-on project. Partnered pupils participate in the design, construct, and test a PVC pipeline maze. Reusable materials and clear...

Clay's as good a material as any to build a boat, right? An introductory lesson sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure the...
