In this science inquiry, students 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, young scholars 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 activity, students will understand that density and weight are different and that density matters in floatation. They...

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.

Learners 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...

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]

Students studying buoyancy will better understand its concepts with this virtual experiment using various balloons and testing what makes them float or sink.

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.

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...

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

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.

In this instructional activity, 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...

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.

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.

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

An experiment in buoyancy which involves making raisins float by using carbonated soda pop. Students then try the same test with other materials. Instructions for making one's own carbonated liquid are also provided.
