Self Assessment

This grid is intended to help you identify your level of confidence, knowledge and understanding related to the area of magnets and magnetism. You can work either on your own or with a partner to identify areas for further development of your science subject knowledge.

Note the date of initial completion of the grid and return to it after you have conducted further study in this area.
