Year 4 Science – Animals (including humans) TEETH!

May 15, 2024Science

Our science topic has been around the types of teeth humans and other animals have and what their purposes are. We’ve discovered that there are lots of things that humans drink that might not be so good for our teeth, causing bacteria build up which eats at the enamel of our teeth and giving us cavities! We know that the surface of an eggshell is similar to the enamel on our teeth so we decided to investigate what the effect of different liquids is on them. We tried: water, tea, milk, fresh orange juice and coke and left the eggshells in them for a week. We couldn’t believe what happened to the eggshells! Just think what these drinks could do to our teeth. Remember to brush twice a day!
