Our Pre-school class simply loves experimenting! In the last few weeks they have been discussing how to take care of and keep their teeth clean and healthy. Their latest hands-on investigation allowed them to see how certain liquids change the color of teeth. They used three common beverages (water, milk, coffee), and hard boiled eggs (teeth) as the tools in their investigation. The results of the experiment amazed them! Their conclusion? "Water and milk are good for your teeth. You shouldn't drink too much coffee!"
