P5 & 6 teeth investigation

We created our own fair test experiment to investigate the effects of a range of liquids on our teeth. We placed egg shells in different liquids for one week. Firstly, we each predicted which liquid we thought would do the most damage. We then observed the changes each day. It quickly became clear that the energy drink did the most damage, followed closely by coke and then orange juice.  

This investigation has definitely encouraged us to take tear care of our teeth!
