This month our problems and games model the process of scientific exploration and discovery.
When you first begin tackling a problem, you might make some observations which could lead to a tentative, incomplete theory or hypothesis. You might try something rather random to test your hypothesis, which you subsequently modify. Then you will become more systematic in your testing and your hypothesis will be reconstructed based on your new insight. At any time, the theory you have is the one that best fits the evidence you have gathered so far. This month's activities have been designed to give you the experience of this process.
This month
The Teachers' Notes accompanying each problem offer guidance to teachers on possible ways of engaging learners in the activity or challenge.
Pupils can submit their solutions to the problems using the 'Submit a Solution' tab at the top of each problem. Solutions to the July problems will appear in September.
