What Floats Your Boat?
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...

Floaters and Sinkers
Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Buoyant Boats
Eureka! Using the clay boats made in the previous lesson, learners investigate the idea of buoyancy and water displacement to finish the last installment of five in a Floaters and Sinkers unit. Their observations during the activity...

What Floats Your Boat?
Learners are introduced to the concept of buoyancy. The Video used in this lesson demonstrates and explains the characteristics of objects that sink and float. It presents the concepts of displacement, weight, and buoyancy.

Thermo and Fluid Dynamics of a Homemade "Lava Lamp"
High schoolers 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.

Freshwater/Saltwater "Eggs-Periment"
Students explore water properties by conducting a class experiment. In this buoyancy instructional activity, students utilize freshwater, saltwater, plastic cups, hard boiled eggs and food coloring to experiment with the floating...

Clay Boats
Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

Day Six: Floater What Ifs
Students observe earth science by examining results from an experiment. In this buoyancy lesson, students practice floating different items in two different liquids and identify why certain objects will float and others sink. Students...

Chemistry: The Case of the Sunken Ice Cube
Students examine a density demonstration involving ice cubes and beakers of water and alcohol. After observing how one ice cube floats in water and sinks in alcohol, they determine which mixture of the two would suspend the ice cube in...
