Joanna Postlethwaite, head of food technology at John Cabot Community Technology College in Bristol, sets Year 7 pupils a task to record their eating habits for 24 hours.
Follow pupils Megan and Ryan as they keep a video diary for the day, recording what they both eat at school and at home, producing some interesting results.
Megan has a fairly balanced diet, whereas Ryan does not. Joanna uses the diaries to explore with her Year 7 class what teenagers need to eat to maintain a healthy diet.
