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.

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.

By the end of this section, you will be able to define buoyant force, state Archimedes' principle, understand why objects float or sink, and understand the relationship between density and Archimedes' principle.

A lesson and activity sheet on buoyancy. Students add weight to a helium-filled balloon to keep it suspended so that it won't float or sink, but instead will 'flink.'

Learn why some things will float or sink.

Students sort objects according to whether they sink or float.

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.

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

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...

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,...

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...

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.

A simple experiment in buoyancy where you discover how to make a packet of sauce or candy float or sink at will, and why you are able to do this.

Students will define density and use the density formula to determine the density, volume, and mass of various items using the correct units for each measurement.

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'.

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

Predict and test everyday objects as to whether they sink or float.

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

Students find the densities of objects based on sinking or floating in this activity that demonstrates Archimedes Principle.

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

This lesson plan is designed to have young children explore the concept of sinking vs. floating by using the skills of prediction, observation and classification.

By choosing the mass, size, and time, students can experiment with whether the block floats or sinks in this simulation. Students have the option to display the forces and add a second block to the tank. Density is also shown to allow...
