Mass, Volume and Density
Test yourself Cards
I can describe the mass and volume of a substance.
The mass of an elephant in space is the same as the mass of the elephant on Earth.
An astronaut weighs more on earth than out in space.
Gravity is the force that pulls everything on Earth towards the centre of the Earth.
I can calculate the density of a substance.
The density of an elephant is its mass divided by its volume.
I can compare the density of materials.
Water is less dense than metal and honey.
Even though metal sinks in water, a yacht can float because its average density is less than water.
The amount of water something displaces shows its weight.
Styrofoam with a mass of 100 g is less dense than 100 g of water.
I can explain the difference in densities of materials using the particle model of matter.
A material that is denser than another material has particles that are closer together.
I can describe methods for altering the density of fluids.
A glass of water with 25 g of sugar is denser than a glass of water with 10 g of sugar.
