This week we have been investigating a change that happens to our body and is very common in Room 7 - wiggly and loose teeth! On Tuesday we did an experiment, in which we used a toothbrush and toothpaste to 'clean' and scrub a boiled egg that had been soaked overnight in Coca-Cola. We thought the egg looked yuck - all sticky and brown - to start with, but were very impressed with the effect of the toothpaste and toothbrush! To make further connections with our learning, we all took home a Colgate Tooth Defenders Challenge - to see if we can all brush our teeth morning and night over the next month!
