An Inquiry based activity that I have done with senior Infants is this:
The effects different liquids have on an egg – transferring this knowledge then to the effects these liquids have on our teeth.
I place 4 eggs in 4 cups with milk, water, juice and coke.
I ask the pupils to make predictions as to what effect each liquid will have on the egg and record their responses.
After 24 hours we observe the cups of liquid and note any observations of changes to the liquid or the eggs.
Link/connect observations with predictions and then apply what this tells us about what is healthy for our teeth.
