How Liquids Affect Our Teeth
This short film clip provides primary teachers with background knowledge on the topic of healthy eating. It demonstrates an effective way of observing the effect of different liquids on teeth. Eggshells representing teeth enamel are placed in water, cola and orange juice and the effects over time are recorded. This resource has been provided by Reach Out CPD, a programme developed by Imperial College London in partnership with Tigtag.
