Year 4 - Most effective toothpaste

Date: 30th Nov 2023 @ 8:50am

This week we tested which the most effective toothpaste is. We observe how damaged egg shells (representing our teeth enamel) were after leaving them in white vinegar for 24 hours. We had one control egg, one egg covered in children's toothpaste, one egg covered in a toothpaste which cost £1 and one egg covered in a toothpaste which cost £5. Which do you think was the most effective? Ask a Year 4 child for the answer!
