Density

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.

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

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

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

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.

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.

… 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?

… 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?

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?

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…
