I have developed this for use predominantly with KS3 but it could also be used at KS4. 1 hour lesson. 1 x PPT which leads the lesson complete with short clips on the problem of over fishing and why it is a problem. Also a short clip on the work of the MSC in regulating fishing worldwide. 1 x Game for the whole class using popcorn and straw to mimic fish and a fishing rod. Students have a short amount of time to 'catch' fish using the straw and then must adjust their strategy to maintain fish stocks for the coming seasons. A practical way of getting students to experience the problems associated with over fishing. Feedback welcome!
