The MWF classes have been talking about our teeth and the care of our teeth. On Friday, I began an experiment with the children. We put five hard boiled eggs in five different liquids. The liquids were water, white vinegar, milk, orange juice and soda (like regular Pepsi or Coke). You could also include Kool-aid, Gatorade, tea or coffee. I introduced the word 'predict'. We predicted what would happen to the eggs in the liquids and recorded their predictions on paper.
I put the milk glass in the refrigerator, left the others on the table and went home for the weekend.
Yesterday we removed the eggs from the glasses. I introduced the word 'observe'. We observed each egg and recorded our observations on paper. We also discussed which liquids were good and bad for our teeth. Science experiments have a definite WOW factor with preschoolers and this was no exception. This is a super easy experiment for you to do at home with your children. Want more science? Go to www.familyfun.go.com and search science.
