He reveals that actually this process has been an integral part of farming since agriculture began thousands of years ago. 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. To grow good food, and enough of it, farmers need to understand the science behind the harvest.

This clip could be used as an introduction to selective breeding. Students could look at examples of plants like the commonly dwarf wheat which was selectively bred to withstand winds which flattened taller crops. This could then be extended to other plants including roses and orchids. Why have these plants been selectively bred? Students will find it interesting that humans began selectively breeding well before we understood simple genetic inheritance. Finally selective breeding could be compared with genetic modification. How are these two processes similar and how are they different? This clip will be relevant for teaching Biology or Science. This topic appears in KS3/GCSE in England, Wales and Northern Ireland and Higher 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.
