I have been creating podcasts to help students revise the OCR A level Biology content. I created this work sheet to use alongside the podcast - I usually do all 4 sheets sheets on one double sided A3 sheet. Students spend 10-15 minutes answering the questions first, listen to the podcast and mark their answers, adding any additional detail that they need in the extra box. The podcast is about 22 minutes long and this activity would fill an hour for lesson time or homework More podcasts added regularly. A lot of work has gone into these resources and your feedback is really valued.
