Year 4 have been learning all about the digestive system, starting at the beginning… the mouth.
This week we investigated how well we brush our teeth. First of all, we brushed our teeth as normal, and then we used special tablets (plaque disclosing tablets) to show up any areas of our mouth that hadn’t been cleaned as well. You can see how they turned plaque purple or pink in our pictures.
We used our science skills to evaluate how well we had brushed our teeth, and how we could make improvements in the future.
