1. How does the composition of matter affect its density, mass and volume?

2. The sand is layered on top of each other
The sand is layered on top of each other. Can this same thing be done with liquids? Explain your thinking.

3. Oil and Water will layer…but do we know why?

4. Density

5. Let’s explore Density more…
If you pick up a baseball and a tennis ball, which one would feel heavier?
Even though they are both of similar size, the baseball will feel heavier because it is denser.
Density is a property that describes the relationship between mass and volume.

6. Let’s explore Density more…
Density how much matter is in a given amount of space.
But what does this really mean?
Density is a property that describes the relationship between mass and volume.
How packed together the matter is in an object

7. Let’s explore Density more…
Which is more dense?
Less dense
Density is a property that describes the relationship between mass and volume.
More dense
Same size box, different amount of matter

8. Let’s explore Density more…
Which is more dense?
More dense
Density is a property that describes the relationship between mass and volume.
Less dense
Same amount of matter, different size box

9. Let’s explore Density more…
Density is how much mass is in a given space [volume].
Can you think of a formula for calculating density given this definition?
Density is a property that describes the relationship between mass and volume.

10. Let’s explore Density more…
Density is how much mass is in a given space [volume].
Density is a property that describes the relationship between mass and volume.

11. … then what is its density?
Density = Mass ÷ Volume
If a block of substance A has a mass of 54g and a volume of 9 cm3
… then what is its density?

12. … then what is its density?
Density = Mass ÷ Volume
If a block of substance A has a mass of 200g and a volume of 50 cm3
… then what is its density?

13. Density = Mass ÷ Volume
I have 3 blocks that are equal in size, but are made of different substances.
Block A has a mass of 280g and a volume of 10cm3
Block B has a mass of 500g and a volume of 25cm3
Block C has a mass of 100g and a volume of 4cm3
Which Block has the greatest Mass? Volume? Density?

14. Density: The amount of matter in a given space.
Density = Mass/Volume
Units for liquids = g/ml
Units for solids = g/cm3
Let’s take a closer look at density…
