GCSE Practical Assessment - Planning

Before you can carry out any experiment, you need to plan it. In many ways, planning is the most important of the skills. If you plan your experiment poorly, you will not only lose marks for skill P, but may also restrict the marks you can get for the other skills too!

So what needs to be in your plan?

A really good plan should contain the following elements:

  • Background information to the experiment
  • Identifying the factors that you could change
  • Choosing a factor to investigate
  • A prediction of the effect of this factor
  • An explanation of why you have made your prediction using scientific knowledge
  • A design for your experiment that is both fair and safe
  • Details about the number of readings you are going to take and why.

What mark will I get for planning?

If you have written a plan, and want to judge what mark it is likely to get, follow the series of questions beginning below

Have you planned an experiment?

A plan for your experiment should be a series of instructions that another person could follow without asking you what you intended to do. It must be a plan for a safe experiment.
