Lesson Title:  A Look at Density and Buoyancy

Software Application(s):  Power Point

Directions:
1. Open A Look at Density and Buoyancy template.

2. On slide 2, discuss terms Density and Buoyancy. Students should type in missing word to complete definitions. (mass, float)

3. Slide 3: Discuss and document the physical properties of the bears.

4. Slide 4: Students should draw conclusions about the density of the bears and that one bear has a different density than the other. Discuss why this is true.

5. Slide 5: Discuss and document the physical properties of the objects.

6. Slide 6: Students should drag objects to correct location on the balance scale and determine possible materials of what each is made. Type in possible answers.

7. Slide 7: Discuss and document the physical properties of the two liquids.

8. Slide 8: Students should infer that one liquid is more dense than the other.

9. Slide 9: Students should document a liquid substance which is less dense than the water.

10. Slide 11: Students should make an inference that the can is not solid. It contains air which is less dense than water.

11: Slide 12: Students should infer that the material in the jar has more mass and is more dense than the water.

12. Slide 13: Students should infer that because the molecules in warm air are further apart, the warm air is less dense than the cool air, thus the cooler, denser air is downstairs.

13. Slide 14: Students should drag objects into the tank of water and place them where they think they would be according to their buoyancy.

14. Slide 15: The students should create a scenario which makes the beach ball more dense in water. They can use drawing tools and/or clipart to create their scene.

15. Slide 16: The students should create a scenario which makes the egg less dense. They can use drawing tools and/or clipart to create their scene.
