After teaching a lesson on the 7 food groups, students use food tests to conclude whether or not McDonald's provides a balanced diet. I buy a big Mac to test. Then watch a short clip on the Supersize documentary and analyse the symptoms of a high fat/high sugar diet; physical and mental. There is also opportunity to evaluate the food tests as methods of identifying nutritional content. I would recommend setting up the food tests as a circus of activities. I have two circuses on the go, so 8 stations. However, this would depend on your lab layout and your class.

Pupils can apply ideas of car safety, to their own car design. They test their design down a ramp, into a wall, using an egg as a test dummy. Self assessment sheet provided.
