Why Do Certain Things Float, While Some Sink?

For Teachers 1st
First graders conduct an experiment. In this density instructional activity, 1st graders work in groups to test 10 different objects to see which ones sink and float. Students discuss why certain objects float and others do not.

What Floats Your Boat?

For Teachers 6th - 8th
Students are introduced to the concept of buoyancy. The Video used in this lesson plan demonstrates and explains the characteristics of objects that sink and float. It presents the concepts of displacement, weight, and buoyancy.

How to Float an Egg

For Teachers 3rd - 4th
Use the scientific method to experiment with an egg. Your class can examine buoyancy and density by finding how many spoons of salt are needed to float an egg. They can predict, experiment, record data, and analyze results.

Sink or Float

For Teachers All
Students experiment with different objects to test if they sink or float. They predict what the object will do before it is put into the water. They are allowed to play with the items after the experiment is over.

Changing the Density of an Object - Changing Shape

For Teachers 3rd - 8th
Continuing with the concept of volume and its effect on density, learners now work with a piece of clay to see if they can get it to float in water. This is a memorable end to a seven-part investigation of density. Make sure to check out...

Comparing the Density of an Object to the Density of Water

For Teachers 3rd - 8th
Investigators construct a makeshift balance and compare equal volumes of wax and water. They do the same for clay and water. Then they discover whether the wax and clay will float or sink in water. Ultimately this is a comparison of...

Water: Float and Sink

For Teachers 1st
First graders work in small groups to observe the tendency to float or sink for a variety of objects in water. They sort the objects and discuss their observations. They use aluminum foil to construct a boat and test it for weight capacity.
