Biology

Cells, tissue and organs
  • State the structure and function of a typical animal and plant cell including, cytoplasm , nucleus, cell membrane, cell wall , ribosomes and mitochondria.
  • How are different cells adapted to their function  e.g. root hair cell for absorption
  • Name and give the function of the main organs and systems of the body.

Reproduction
  • Explain the structure and function of the male and female reproductive system. 
  • Understand the menstrual cycle. Describe the secondary sexual characteristics due to puberty.
  • Explain what happens during fertilisation, implantation and the development of the baby during pregnancy. 
  • Birth
  • Sexual reproduction in plants, the structure and function of the flower.
  • Pollination insect and wind

Physics

Energy
  • Explain the different types of energy e.g. heat, kinetic, light, sound, chemical
    and gravitational.
  • Law of conservation of energy and energy
    transfers

Electrical circuits
  • Series and parallel.
  • How to measure current using an ammeter and voltage using a voltmeter.

Forces and motion
  • Understand that forces are pushes and pulls etc.
  • Forces change the speed, size and shape of an object.
  • Gravity is a force and weight is the force of gravity on mass. 1 kg = 10 newtons.
  • Balanced and unbalanced force diagrams where the arrows show the size and direction of force.
  • Speed is distance /time and can be graphed on a distance time graph.
