Science Experiment - Looking After Your Teeth
Today we are going to start looking at a science experiment. Don't worry you don't need to have all the equipment ready today. You are going to read the method and make a prediction today, and then on Friday you are going to set up the experiment.
You're going to study what happens to egg shells over 5 days when you put them in different liquids. We are using egg shells because they are made of a similar material to teeth, so will react to the liquids in a similar way.
You will need:
- enough egg shell to put in 5 different liquids
- half a cup of cola, milk, fruit juice, water and vinegar.
Read the sheet for more information and then write your prediction. Why don't you share your prediction on the blog?
