Students determine whether a liquid will sink or float in water by comparing its density to the density of water.

A learning module geared toward English as a Second Language Learners. Students read and/or listen to a short text entitled "Fishing Boat Sinks, Everyone Saved" and click on the links below to increase comprehension and vocabulary...

This is an educator's guide for a unit on things that sink or float. It includes lesson plans, experiments, and activities. Students apply the scientific method as they investigate whether objects sink or float.

A new take on the sinking of the Bismarck. Due to finding the actual sunken ship, possible evidence was procured that may support the idea that the Bismarck was actually scuttled by the Germans. Regardless, the sinking of the Bismarck...

See how different solids can have different densities depending on their molecular make-up.

Students investigate with common objects to see if they can make something that neither floats nor sinks, but rather "flinks" in the middle.

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.

The tradebook, Who Sank the Boat? by Pamela Allen, is an excellent tool in teaching measurement. Young scholars will engage in activities involving different types of measurement. In the story, five animal friends decide to take a boat...

A brief description of the sinking of the Lusitania and why that occurance eventurally broke down American neutrality, and the United States finally entered World War I.

For a dramatic illustration of density check out this demonstration. It's simple to do, only requiring a bowling ball and some water.

Could you use plastic bottles, popsicle sticks, and tape to Engineer a catamaran that can hold 15 ounces of cargo without sinking? Use this site for lesson plans, tips, and a place to document your process.

Learn about density in this hands-on science experiment. Includes full list of materials, procedures, and scientific explanation of what makes an object float or sink. [PDF]

Whether your child is lost in a haze of elementary grammar rules, sinking fast in a jumble of Newton's laws in middle school, or lost in the details of an AP biology class, you need help quickly, before your child falls way behind the...
