Science at key stage 3    (Year 9)

Unit 9J: Gravity and space

QCA
About this unit

In this unit pupils:

  • learn about the gravitational pull between bodies; how it depends on the masses of bodies and the distance between them
  • relate the movement of planets around the Sun, and that of satellites around the Earth, to gravitation
  • study how artificial satellites are used to observe the Earth and provide information about the solar system and the universe
  • find out about space exploration

In scientific enquiry pupils:

  • consider different views of the nature of the solar system and evaluate them against relevant evidence
  • discover how scientists work together to gather and interpret evidence from space
  • make predictions from patterns in data
  • consider and evaluate conflicting evidence

This unit is expected to take approximately 7.5 hours.
