**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…
