1. Density

2. Density – How much mass is in a given volume

3. In my own words How tightly packed the particles are

4. Density = Mass Volume Units – Kg/L, g/ml or g/cm 3

5. Ex: Gold density is 19.3 g/cm so 1 cubic cm will have a mass of 19.3 g 3

6. Aluminum is 2.7 g/cm 3 How much mass will 2 cm 3 have

7. 4 Basic Principles of Density Can you guess them

10. Principle 1: If you pack more mass into the same volume, it's more dense.

12. Principle 2: If you pack the same mass into a smaller volume, it's more dense.

14. Principle 3: Just because something has more mass doesn't mean it's more dense.

16. Principle 4: If it is the same material, then it will be the same density, no matter the size.

17. Density Of liquids

20. Density Explanations w/ apt clock

21. Why does a helium balloon rise up?

22. Why do you float better in the ocean than in a pool?

23. Density Explanations Why do you can float on your back when you inhale, but sink once you exhale?

24. Explain Lava Lamps

25. Density Animations How much of an object floats above water?

26. Density Math D=M/V D M V D = ? M = 6g V = 3ml

27. Density Math D=M/V D M V D = 4g/ml M = 12g V = ?

28. Density Math D=M/V D M V D = 5 g/ml M = ? V = 3ml
