We have been doing lots of science experiments this week as part of our fair testing unit.
In this experiment, we soaked chicken bones in vinegar for 5 days. When we took them out, all of the calcium had been drawn out so the bones were really bendy! It showed us why we need to drink milk - we don't want our bones to bend like that from a lack of calcium! To make this a fair test, we are going to do the experiment again and put the bones in wine vinegar, malt vinegar and white vinegar and compare the results.
In this disgusting experiment, we put half of a tooth into a bottle of Coke and put half the tooth in water. We checked it 24 hours later and were horrified with the results!
The half that had been in water was still perfect - white and clean. The half that had been in Coke was about a quarter of the size and brown with holes in it! We now realise the damage Coke could do to us it we drink it too often!
It was great to see some of the science experiments you have been doing. The one with the teeth in coke was gross - I'm glad my kids don't like coke! Keep the blogs coming, it's always interesting to see what you are learning.
ReplyDeleteNow you know why us parents always nag our kids to brush their teeth!!!

Imagine what Coke does to your kidneys! Well done for preparing and demonstrating some really interesting experiments.
ReplyDeleteGood experiment with the coke. Hopefully now you realized why I only let you have coke as a treat sometimes, and not as an everyday drink.
