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.

A lesson where students 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 cold,...

Sixth graders predict if different types of coke will float or sink.

For this activity, young scholars investigate whether objects and liquids float or sink when placed in water. As they proceed, they will develop an understanding of what density is. Student handouts are provided.

An experiment in density. After a review of floating and sinking of different materials, learners 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...

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

Students determine whether an object will sink or float by comparing its density to the density of water.

In this science inquiry, learners investigate whether volume or density of objects determine the floating or sinking in water. Using a rock and a block of wood teachers engage students in the discussion of density, mass and volume.

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.

In this activity, students will learn about density by determining how to make an egg float in water. By the end of the instructional activity, students will understand that density and weight are different and that density matters in...

Students investigate water by estimating how long it takes to freeze, then see if the ice cube will float in water, and eventually work with other items to see if they sink or float in water.

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

Students experiment with items that sink or float, and learn that water's density is equal to one, and objects/solutions with a density greater than one will sink, and those with a density less than one will float.

In this lesson, students will listen to nonfiction books about items that sink and float. Students will participate in filling in words to fill in a teacher-created chart that is connected to the information. Students will then write a...

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...

A collection of interactives, videos, and documents on a variety science concepts.

In this lesson, students will investigate different categories related to safety, organisms, sink or float, boats, seeds, and water droppers. Students will use exploration tubs to make observations.

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

Throughout the activities in this investigation, students may have wondered how a boat made out of steel, which is more dense than water, can float. This activity addresses that question. Students will see that changing the shape of an...

[Free Registration/Login Required] Students will be able to change the mass and volume of an item and observe if it floats, sinks, or remains at a certain depth in the water. Students will also be able to change the liquid in level 2.
