Primary 6 have been completing our health and well being topic about nutritional values of our food and drinks. We learned about the sugar in our drinks and were amazed to see the amount in some of our favourite drinks! We created a ‘think before you drink’ display to remind us just how unhealthy these drinks are and to make us think twice about buying them regularly!
This week we completed an experiment with eggs to find out what these drinks can do to our teeth! Mrs Thomson boiled us some eggs and we put them into cola, coffee, tea and water. We left them for 5 days… not only did they smell bad, when we removed them they looked disgusting! The tea, coffee and cola all stained the eggs… the coffee was the worst; it stained the inside of the egg when we cut it open! The egg that we left in water was perfect, it was not stained at all. We got some toothbrushes and and tried to see if any of the staining would come off but it didn’t! The egg soaked in cola was slimy and solid to cut! Yuk!
We also looked at calcium in bones and teeth! We soaked some bones from chicken drumsticks in vingear, the acid made the bones very easy to bend, this showed us the importance of drinking calcium based drinks and food!
