Recap and recall
Before starting this unit, check the children can recall the following ways of using forces to change the shape of materials from the unit Science, Year 3/4 (B), Forces and space: Forces and magnets: Forces (push, pull and twist). Contact forces (friction). Non-contact forces (magnetism and gravity). Use the Activity: Unbalanced forces mind map (one…

Adaptive teaching
Pupils needing extra support
Should draw the diameter of one of the rocky celestial bodies (Pluto, the Moon, Mercury, Mars, Venus or Earth) as these have smaller diameters and are easier to measure and draw; could draw the diameter of their allocated celestial body as a straight line rather than drawing a circle to represent its correct shape; could use the Resource: NASA data table (support) to research the gravity for the celestial bodies; could use the Knowledge organiser to support their understanding of gravity.
Pupils working at greater depth
Should try and explain why Saturn has less gravity than Neptune using their understanding of the relationship between Mars and Mercury and their masses, diameter and gravity; could choose an extension activity relating to gravity from the Resource: Stretch and challenge: Unbalanced forces.

Knowledge outcomes
- I can define gravity as a non-contact force that pulls objects towards one another.
- I can explain why unsupported objects fall towards the Earth: the Earth’s gravity pulls the objects towards its centre.
- I can describe the relationship between mass and gravity; the larger the mass, the greater the gravity.
