Why is chocolate bad for dogs? Caitlin and Rebekah take a look…

Leave a comment

Regular readers of our blog will know that we have been looking at Year 9’s exploration of their chosen science topics for the Bronze CREST awards. Caitlin and Rebekah decided to look at chocolate – how it is made and how it affects our brain.

“One of the many things we discovered about chocolate is is that there’s quite a lot of the chemical theobromine in it,” they said, “and that can kill dogs if they have too much of it. Another interesting fact is that chocolate – or, at least, the cocoa bean it is made from –  used to be worshipped as a god by Mayan Indians of Mexico 1500 years ago!”

CREST is a UK award scheme recognising success, building skills and demonstrating personal achievement in STEM (science, technology, engineering and maths) project work.
