Why is Science important?

In Science at Key Stage 3 pupils learn about how scientists work to develop theories, present data and the ways scientists communicate.  At KS3, our team of specialist teachers deliver Biology, Chemistry and Physics in a wide range of theoretical and practical learning opportunities.  We believe Science should generate awe and wonder and stimulate a desire to explore the world around us in exciting and creative ways. As well as increasing subject knowledge, KS3 pupils develop their confidence, teamwork and problem solving skills by designing and carrying out investigations.


Key Skills Required

Pupils follow the new Programme of Study at KS3 with a greater emphasis on How Science Works (HSW), the relevance of Science, and how Science can impact on everyday life.

HSW develops skills and lays the foundation for success at KS4. It has five key elements, and across a range of contexts and practical situations pupils will be:

  • Thinking: using ideas and models to explain the world around them.
  • Understanding: explaining the economic, ethical, social and cultural implications of science 
  • Communicating: presenting scientific ideas and understanding how scientists communicate. 
  • Investigating: planning, carrying out and gathering evidence from a wide range of experiments. 
  • Using: gathering information from a variety of sources, taking into account errors or bias, to explain their ideas.


Topics Covered in KS3

Number of lessons per week: 3

  • Working Scientifically
  • Cells
  • Particles and their Behaviour

Pupils should expect to do a science homework project once each term in addition to the regular science homework.


Assessment Details

Pupils will sit one formal assessment test at the end of the year.  Further assessments of their Levels will be made using formative 'Levelling Tasks' and short end of topic tests throughout the year, with the aim of developing their revision skills.

Key Tips for Success

1. Create a revision timetable.

2. Practising past papers will help you get familiar with exam format, question style and time pressure and help you retrieve information quickly.

3. Use mind maps to connect ideas.


How can a parent help their child succeed in this course?

Creating a revision timetable is a great way to help your child organise their study time, plus it also helps boost motivation to revise for exams. Recognising a need for a revision timetable means that you have already made a great start to combat exam stress.
