How to use these science presentations
Each presentation was made by a teacher for a real lesson, so you can use it as it is or adapt it to your class. Download the file, open it in PowerPoint, Google Slides or Keynote, and change the wording, examples or level to suit your students. Many work well as lesson starters, revision recaps or homework support.
The presentations cover the main topics taught in secondary school science, including the AQA, Edexcel and OCR GCSE courses and A level biology, chemistry and physics, with some primary and KS3 material too.
