1. School Name Date Volunteer Name Buoyancy

2. A little bit about me. Why is buoyancy important? What are we going to do today? Learn about buoyancy. Learn how to compare the buoyancy from different liquids on an object. Learn how the density of an object and the density of a liquid relate to floating and sinking. Introduction

3. Buoyancy Exploration Buoyancy steps on the Web Prepare your materials. Do the activity. Discuss your results. Think of extension ideas.

4. Virtual Buoyancy! Buoyancy Explorer on the Web Select your liquid. Select your material. Drop the block. Discuss your results. Think of extension ideas.

5. What can you do with your new knowledge? What problems can you solve? What predictions can you test? What other things can you do with this idea? Now What?

6. A solid object in a fluid is acted on by an upward force called buoyancy. The strength of the upward buoyant force on an object in water is equal to the weight of the water pushed aside by the object. If the buoyant force is greater than the weight of the object, the object will float. If the density of an object is less than the density of the liquid, the object will float. Buoyancy Summary

7. Search for more buoyancy information on the Internet. Use this to create a presentation. Use Scratch or Microworlds to make a buoyancy animation. Develop a song or skit about buoyancy. Do a buoyancy project with another school. Create a report or video for publication. Follow-Up Ideas
