1. Density

2. Remember: All objects are matter Define matter?
So, matter is made of what two physical properties?(Hint: in the definition)
Mass and Volume

3. Mass Mass is the amount of material an objects has in it.
What tool do we measure mass? Triple Beam Balance with grams as the unit

4. What is Volume? The amount of space that matter takes up
What tool do we use to measure volume?
Graduated cylinder, beaker or measuring cups
Let’s demonstrate!

5. What is Density? More mass, more dense Less mass, Less dense
Density - looks at the mass (amount of matter) and volume (size of an object)
Different matter has different densities
More mass, more dense
Less mass, Less dense

6. Different matter has different volume (size) Which one has more density?

7. Does bigger(more volume) mean more mass? Which one is more dense?

8. Which one is more dense?

9. Which one is more dense?

10. Which one is more dense?

11. Which one is more dense?

12. What is Buoyancy?
Buoyancy - matter’s ability to float or sink in a liquid.
