This week, year 4 have been investigating how different drinks might affect the enamel of our teeth. We began by considering the ingredients in drinks and predicting which drinks would have the worse impact. Carefully measuring to ensure consistency, each tooth (or egg) was submerged in each group’s chosen drinks. Next week will be egg-citing as we see how things develop.
Update: After leaving the teeth for a week, our senses were overwhelmed whilst we analysed the results. The children used descriptive vocabulary to label diagrams such as “crater”, “peeling”, “cracking” and “stained”. It was amazing to see the orange juice had formed barnacle type formations on the egg (teeth enamel). The stench of sour mouldy experiments was egg-traordinary and we are glad that they have now been removed from the classroom.
