In this topic you will learn about weight mass and gravity. You will learn about how big Space really is and what our solar system is made of!

Here are the learning objectives for this topic:

I can
  • Calculate weight on earth
  • Name the parts of our solar system
  • Order object in space by size
  • Explain why gravity changes in different parts of the solar system
  • Name the two types of satellites
  • Describe the different types of artificial satellites and their uses

I understand
  • That gravity is a force that acts between all objects
  • That gravity decreases with distance and smaller objects
  • That gravity holds the planets in orbit round the sun
  • That artificial satellites have many different purposes
