In science, we have been investigating the effects of different liquids on our teeth. We put eggs into 7 different liquids - cola, diet cola, milk, water, coffee, tea, apple juice - and left them for several days to see what happened (eggshell and tooth enamel both contain calcium carbonate which dissolves in acidic conditions). For our experiment, we predicted what we thought might happen to the eggshells, left them for several days and then observed the changes and the reasons for them. We also tried brushing them with toothpaste to see how that helped. A thought-provoking experiment which may well affect our drink choices in future!
It's always fantastic to see the amazing home learning that the children have completed, and we were blown away by the creative digestive system-related work this term.
Over the last few weeks we have been busy creating non-chronological reports all about teeth in our English lessons. We researched information, wrote our own texts and then presented them as double-page spreads in our books. We're blown away by the pride the children have taken in these reports both with the content and presentation. Well done, Year 4!
