Lesson Details
Key learning points
- Volume is the amount of space that an object takes up.
- Objects with the same volume do not always have the same mass.
Common misconception
Pupils may think that the taller the object, the greater its volume.
Use 3D objects as much as possible to compare, so pupils can develop their appreciation for multiple dimensions that contribute to the object's volume.
Keywords
Volume - The amount of 3-dimensional space something takes up is called its volume.
