Use the Sink or Float Worksheet with the "Sink or Float?" science project to encourage kids to make predictions, perform tests, and record their results. To test even more objects, print out multiple copies of the page. Fruits and vegetables are also fun things to test for floating abilities. Discuss why some things that are filled with air float in water (here are some ideas - a rubber duck, a hollow plastic ball or tennis ball, a bell pepper, and a empty glass bottle or jar with a lid).
