This resource is for students studying the new 2016 syllabus of GCSE Physics OCR Gateway exam board (although the AQA exam board is similar but in a different order).
It is the COMPLETE series of lessons for P4: Waves and Radioactivity. I chose to use the relevant OCR worksheets to accompany the lessons, if you have access to Kerboodle you can find these on there. These ppts took me ages, I hope they save you time!
Please let me know if there are any resources to go with the ppt missing, or any mistakes and I will correct. Alternatively, please comment and let me know if they have been useful :).
