Read through the PowerPoint below to find out about how to help teeth stay healthy. Follow the instructions on the document below to carry out an investigation. Choose three drinks/ liquids to test but one must be water. You could use water, orange juice and cola or water, vinegar and black current squash or your own combination. Set up the experiment as described replacing the liquids each day for the next week. Complete the investigation sheet remembering to make your prediction before you start. There is space for you to add drawings or photos at the start and end of the investigation. I'd love to see some pictures of what happened so please send them in next week when you have finished.
