Last week, we learnt about teeth! We brushed our teeth and then used disclosing tablets to show what we missed. We had super clean teeth by the end of the day!

We have been scientists this week!

First, we investigated how to look after our teeth:

We looked at the results of the egg experiment we started before half term. We placed eggs into different liquids ( water; orange juice; cola; energy drink and vinegar ) to represent the sugars and acids in the foods and drinks we consume. Our results we amazing – the energy drink’s shell had become a powdery crust and the shell of the vinegar egg completely dissolved, turning the white of the egg completely solid and making the egg resemble a bouncy ball. This showed us that sugars and acids have a negative effect on our teeth.

Building on the experiment, we then looked at how well we clean our teeth, by using disclosing tablets to highlight areas of our teeth we might miss when brushing. We had some very sparkly teeth at the end of that session.

Finally, after learning about the digestive system, we created ‘poo’ in the classroom! Using biscuits, banana and orange juice, a long tube, a funnel, a pair of tights and a knife and fork, we recreated the mechanical process of how we digest our food. We had a gross alert and a few couldn’t watch – but we did have fun!
