Year 7 revision topics for end of year exam 2014

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

 Chemistry

Acids and Alkalis

• Indicators and pH scale
• Neutralisation
• Examples of neutralization reactions.

 
Particles and reactions

• Understand the particulate theory of matter in solids , liquids and gases.
• Physical changes such as dissolving and changing state, melting, evaporating, freezing and condensing
• Understand what is meant by a chemical reaction and write simple word equations for oxidation reactions, and combustion.
• Understand that mass is conserved during a chemical reaction.

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.

Investigative Skills
Students also should be able to identify/suggest variables in a practical investigation (dependent, independent and controls), analyse data  (draw/read graphs) and draw conclusions based on evidence from data.
