Students sort objects according to whether they sink or float.

The RMS Titanic was a British passenger liner that sank in the North Atlantic Ocean in the early morning of 15 April 1912, after colliding with an iceberg. More than 1,500 passengers died as a result of the ship sinking. After the ship...

[Free Registration/Login Required] An informational text about the sinking of the submarine the Lusitania during World War I. A question sheet is available to help students build skills in reading comprehension.

[Free Registration/Login Required] An informational text about an idea that might keep the city of Venice, Italy from sinking. A question sheet is available to help students build skills in reading comprehension.

Students will investigate what determines whether a material will sink or float. They will be given a bowling ball and have to make measurements and conclusions on whether their bowling ball will float, hover, or sink when placed in an...

In this lab activity, learners use a chemical indicator (bromothymol blue) to detect the presence of carbon dioxide in animal and plant respiration and in the burning of fossil fuels and its absence in the products of plant...

In this experiment, you test whether two different bowling balls will float or sink, then determine the density of each of the balls to see if they are less than that of water.

In this activity, students carry out financial computations, involving annuity, and the future value of annuities. Students also deal with computations involving sinking funds.

An experiment in density where colored water, both hot and cold, are poured into containers of water at room temperature. Students will observe that the warm water rises and the cold water sinks due to their different densities.

This investigation introduces the concepts of volume, mass, and density and how they interact. Students will make predictions of whether an object will float or sink after finding mass and volume of an object.

NorthPark University offers several informative paragraphs on the sinking of the Lusitania, a British cargo and passenger ship that was torpedoed and sank due to German submarine activity on May 7, 1915.

Text of a statement by William Jennings Bryan protesting the sinking of the Lusitania by German U-boats.

Through flashback, L.D.Cox tells how he survived the sinking of the U.S.S. Indianapolis during World War II in this segment from History Detectives.

[Free Registration/Login Required] Drabble does not come out well in this "New York Times" review. The critic's comments on Drabble's characters and discussion of the influence of Virginia Woolf and Charles Dickens provide insight into...

Collection of photographs related to the sinking of the battleship Maine.

An experiment in density. After a review of floating and sinking of different materials, pupils test four bottles, all holding four ounces of water, to see if they will float or sink. They each contain a different density of sugar water,...

An experiment to determine if either a regular or a diet can of soda will float or sink when placed in water, and what causes this.

For this activity, students make predictions about whether different objects float or sink, then test them. They are asked to record their observations and results for each, and compare their results to others'.

This article explains the buoyant force using a submarine as an example. It also discusses what determines the size of the buoyant force using a formula, and explains decompression sickness better known as the bends.

In 1912, popular media headlined the sinking of the world's largest luxury passenger ocean liner while on its maiden voyage. Newspapers captivated the world's attention with stories from survivors and about victims who did not survive....

A lesson where young scholars learn how warm water is less dense than cold water, and what this means for global climate change as ice from the polar regions melts. Students will do experiments in buoyancy and water density when hot or...

This site discusses article discusses the rules of conduct regarding disclosure of personal and military information that may have compromised military efforts during World War II.

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

PBS documentary about famous shipwrecks reviews the sinking of the Lusitania and the salvage efforts undertaken by deep-sea archaeologist Bob Ballard, who explored the wreckage in 1993.
