Lesson Plan #: AELP-SCI0025
Submitted by: Dawn Nelson
Date: November 9, 1998
Grade Level(s): 3
Duration: 45 minutes
Description: Students will recognize what makes a clay ball float.
Goals: experiment with clay to recognize what makes something float
Materials: container, water, balls of clay
Assessment: After many have achieved their goal and their clay floats, draw some pictures on the board.
I usually follow this lesson up with using everyday materials and predict and test if they float. I also discuss submarines and what makes them float and sink. There is a really cool experiment with simulating a submarine using a 2-liter soda bottle with holes in it connected to a tube (usually the tubing for a fish tank works great). They love to blow in the bottle and watch it rise out of a container of water!
