Tooth Decay Experiment
Last week as part of Year 4's science topic of animals, which includes humans, we looked at our teeth and what they are called and their functions. Then we compared human teeth with animal ones, how food habits influence their shapes and use. We also investigated how clean our teeth are using disclosing tablets, a horrifying experiment for most but lots of fun! This allowed us to reinforce the importance of brushing our teeth well and to discuss tooth decay and its implications. Hopefully there will be no excuses to not brush their teeth to parents!
