Y5 Floating and Sinking

Pupils learn about the forces of gravity and upthrust. They learn that gravity is the force that pulls thing to earth and upthrust is a force that resists this. They learn that water can produce upthrust and when the force of gravity and the upthrust are equal objects on water can float.

Learning Objectives:

  • PoS - identify the effects of air resistance, water resistance and friction, that act between moving surfaces
  • WS - pupils should take measurements, using a range of scientific equipment, with increasing accuracy and precision
