​
The Science Badge programme allows students to follow science field(s) of interest. To gain a Science Badge, they need to complete 20 points from a range of activities of their choice outlined on the Science Badge card. The work is to be checked, evaluated and, in some cases returned, until it is at a suitable standard.
They can work on their projects at school during flexi-time and/or at home if they wish.
