To grow good food, and enough of it, farmers need to understand the science behind the harvest. Our ability to feed ourselves all hinges on the fact that plants can create their own food through the process of photosynthesis. Food fanatic Stefan Gates explores what’s going on within the process, and reveals how we can actually see photosynthesis in action with the use of some simple aquatic plants, a fish tank, and a light. At a massive tomato greenhouse in Kent, Stefan discovers that farmers can artificially create the ideal conditions for photosynthesis to produce a bumper crop of tomatoes - even in winter - keeping us supplied with tomatoes all year round. This clip is from the BBC series Science of the Harvest. Food fanatic Stefan Gates explores the science behind agriculture's most important event, harvest.

This clip could be used very effectively to review photosynthesis learning in previous years and illustrate to students the factors that affect the rate of reaction of photosynthesis. They could complete the pond weed experiment shown in the clip. In this the light intensity is varied by moving a table lamp progressively further away. To show that more photosynthesis occurs with high concentrations of carbon dioxide they could simply add more sodium hydrogen carbonate to their solution. This could also be used for students to understand the uses of glucose. This clip will be relevant for teaching Biology. This topic appears in OCR, Edexcel, AQA, WJEC KS4/GCSE in England and Wales, CCEA GCSE in Northern Ireland and SQA National 4/5 in Scotland. ===================== For more clips from other subjects at the BBC Teach YouTube channel: http://www.youtube.com/bbcteach More resources for teachers from the BBC: http://www.bbc.co.uk/teach More from BBC Learning Zone: http://www.bbc.co.uk/learningzone More resources from BBC Bitesize: http://www.bbc.co.uk/education ===================== Subscribe to create your own customised playlists, and get notified about our latest clips.
