Why does a seastar sink, but a jellyfish float? Through a fun investigation, learners examine the concept of buoyancy using simple household items. The challenge: create neutral buoyancy for an action figure in water. With ample...

Students design and execute a lab through which they study the distinctions between density, buoyancy, and volume.

Will your next buoyancy lab rise to the occasion? Make a splash with action figure divers! Teams of young physicists explore the relationship between mass and buoyancy by adding weights or balloons to achieve a diver that neither sinks...

Middle schoolers examine buoyancy.  In this density lesson students form a hypothesis, collect data and draw a conclusion using the data. 

Students visit a swimming pool and brainstorm different water sports and what benefits swimming has over other types of exercise. They then discuss buoyancy and water pressure and when how objects sink or float before playing a game of...

A referenced PowerPoint is not included, but this lesson can still make an impact with emerging environmentalists. After introducing them to the facts about overfishing, they experiment with a fishing simulation using colored beads and...

Young scholars compare and contrast the coelacanth, a living fossil, with a moray eel and a bull shark. They complete a Fish Anatomy worksheet while researching the skeleton, body coverings and buoyancy of each fish.

Young scholars explore how fish are able to move easily from one depth to another in water.  In this fish lesson students create their own balloon fish. 

[Free Registration/Login Required] An informational text about the positive effects of swimming. A question sheet is available to help students build skills in reading comprehension.

SPRK STEM challenges are fun, interactive activities that challenge students to use creativity and team-work to move through simple steps of the design process in order to build Sphero-based creations. The Hydro-hypothesis challenge...
