Science with our buddies - Does coke affect our teeth?
Our buddy class Room 11 are investigating "does coke affect our teeth?" They invited us to see what happens when you compare an egg soaked in coca cola for a short time and brushed with toothpaste, an egg soaked in coke for long periods and "Mr Control", a plain egg. Egg shells make good substitute "teeth"!
Scientist Harriet helped with the tooth brushing.
We used our eyes to observe, and our fingers to feel any changes.
Mr Control was clean and smooth, the brushed egg brownish and the soaked egg blotchy and rough to touch.
Room 1 now think that coca cola is a "sometimes treat" and they should brush their teeth afterwards!
