Why the teacher loves Milk Tray
A group of teachers from Findlay, Ohio, are using everyone's favourite snack as the basis for teaching science, and the pupils cannot get enough. According to Mike Eier, chocolate is the perfect compound for demonstrating a host of scientific principles.
Presenting his work at the Association for Science Education conference, he said: "It is an immediate attention grabber when the kids come into the classroom and it can be helpful in teaching just about every scientific concept, fromsolubility to nutrition."
Hershey Bars are used to test chocolate density, Graham Crackers explain the theory of plate tectonics and Mars bars are used to demonstrate geological strata.
And as long as supplies last, chocolates can also be used in maths (count the Mamp;Ms), geography (which nation consumes the most chocolate?) and history (from Aztecs to the Swiss).
The only drawback, as the very well-attended workshop at the association's conference demonstrated, is how to prevent pupils and teachers eating the evidence.
