## Lesson details

### Key learning points

- The size of something does not determine how much mass (or matter) an object has.
- Taller containers do not always hold a greater volume of liquid.
- If you know the mass and volume of some objects, it is easier to estimate others by comparing them.

### Common misconception

Larger objects have a greater mass. Taller containers have a greater capacity and/or volume.

The size of something does not determine how much mass an object has; taller containers may be narrower and so may not hold as much liquid.

### Keywords

Estimate - An estimate is a given value, number or quantity that is near to the true amount; it is a number close enough to the right answer.

Mass - Mass is a measure of how much matter something contains. It is measured by how much something weighs. Mass can be measured in g or kg.

Volume - Volume is the specific amount of liquid in a container. Volume can be measured in millilitres or litres.
