In this activity, students investigate the history of density, its uses, and applications. Students will generate and calculate data applying it to a graph. They will be looking at the relationship between mass and volume.

With the subtitle, "stuff you should know before delving too far into Chemistry," this site examines a range of six topics to provide the user with a broader understanding of chemistry.

This site will tell you how you can use an egg to identify air pressure and how it affects objects. Includes easy step by step instructions.

Deepen the students' understanding of density by constructing a simple hydrometer that can be used to compare the densities of different solutions.

Use a condiment packet as a Cartesian diver to show how pressure changes cause the "diver" to float, sink or hover.

Become an engineer, and design a submarine that moves in the water like a real submarine. Try making it sink, float, and hover in the water.

[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.

Students figure out how much mass can be put in a boat without having the boat go fully under the fluid.

Students must figure out how much of a ball will be under a fluid when it is in equilibrium with its environment.

Tells the story of how Archimedes discovered the Archimedes Principle and his water displacement method for determining the volume and density of an object. Provides an explanation and several examples of how it is done.

An app that demonstrates the Law of Archimedes. This virtual experiment will show students that by changing the shape of the solid, the amount of liquid displaced will change.

Try out these experiments you can do with items you might already have around the house: "Two Ball Bounce," "Cartesian Diver," "Straw Flute," "Bernoulli Ball," and others. Two experiments, "Imploding Pop Can" and "Balloon in a Bottle,"...

[Free Registration/Login may be required to access all resource tools.] Archimedes Law: displacement and buoyant force and why some objects float.

Students will explore matter that sinks or floats when submerged in water and that matter is categorized as either a sinker or a floater. Students will work actively in small, cooperative learning groups as well as gather in a whole...

Review and study pressure and force in regards to fluids.

Build your own bathtub or pool toy from simple craft materials in this fun activity. You will build a rubber-band-powered boat that can zip across the surface of the water after you wind up the rubber band.
