Young scholars conduct a series of investigations on the unique properties of water. In this general science activity, students explain what causes water's surface tension. They explain the different stages in the water cycle.

Students examine distribution of water and minerals. In this surface and groundwater lesson, students conduct an experiment with fresh and salt water making hypothesis and drawing conclusions about minerals. 

Here is an exciting, and meaningful science instructional activity on the formation of bubbles! Young scientists have three cups with a variety of solutions in them. One cup has detergent only, one has glycerin added to it, and the third...

Students determine the contact angle of water on different surfaces. In this physics lesson, students calculate their percent error using a mathematical formula. They explain the advantages of using non-wetting surface for certain...

Students review background information about water tension and adhesive forces on sand. In this sand science lesson, students visit a beach and have a sand building competition near water and away from it. Students discuss water tension...

Students analyze density. In this density activity, students experiment with floating an egg. Students discover that salt added to water changes the density of the water allowing an egg to float.

Students explore magnification. In this science skills observation lesson, students make a hand lens using a wire loop and a small amount of water.

Students construct their own lava lamp using simple substances. In this physics lesson, students explain how difference in density causes convection. They solve for forces and buoyancy using mathematical equations.

Students complete activities to learn about rainbows and the importance of dairy in their diet. For this sense and diet lesson, students discuss rainbow colors, the importance of sight, and the importance of dairy in a healthy diet....

Students examine the concepts of forces and motion. They work together to design protective devices for their egg rovers as they are dropped from a specific height. They record their observations and discuss.

Students watch a video clip about German submarines lost during World War II. They work together to create their own submarine out of a plastic bottle. They test the buoyancy of the submarine in different activities.

Students discover fluid dynamics related to buoyancy through experimentation and optional photography. Using one set of fluids, they make light fluids rise through denser fluids. Using another set, they make dense fluids sink through a...
