## Lesson details

### Key learning points

1. Different containers have different capacities - they hold a different amount of liquid.
2. We can use the scale on the measuring container to tell us the volume of liquid in the container.
3. The volume of liquids in different containers can be compared using the scale.

### Common misconception

Confusion between the terms capacity and volume.

Capacity is the whole amount of liquid that a container can hold. Volume is the actual amount of liquid in the container.

### Keywords

• Capacity - Capacity is a measure of the maximum amount of liquid a container can hold when full. Capacity can be measured in millilitres.

• Volume - Volume is the amount of space that an object takes up. In this case, the specific amount of liquid in a container.

• Milliliitre - The millilitre is a metric measure of capacity or volume. A millilitre is a very small amount of liquid. The abbreviation is ml.

Lesson practical where possible. Children need to experience containers that have different capacities and different volumes of liquids in them. Children need to get a good understanding of the difference between capacity and volume.
