Rot ya teeth

Lately for the past few weeks we have doing work around science, such as learning new vocabulary and doing our own experiments. We first started learning about a scientist called Isaac newton and his laws of gravity. Then we went on the work i groups of three for a balloon race, which is a fair test showing how fast the balloon attached to a string with a straw can travel. In the balloon race we kept track of the time of the balloon while it was traveling across the room. We also also measured the balloon using a tape measure.

After we did some research and a DLO we then went on to create our won experiments in groups which were chosen by Ms Wilton. When we did this group project, we got paired up with people we don't usually work with. Myself, Felix and Lauren all discussed a topic to choose for our science fair test. If you don't know what a fair test is a fair test is an experiment that has all the same factors and a variable that you are able to change.  

My groups fair test was an experiment about how fizzy can rot your teeth; we used cola, cola no sugar, lemonade, and lemonade no sugar. We used eggs to replicate teeth for our experiment, we filled all the drinks into four cups. We first made our own hypothesis, which is a prediction about what was gonna happen with our experiment. To make sure it was a fair test we filled them up to the same amount at the first line of the plastic cup.  We left our eggs to sit in the cups for two days we checked the results, then we put them back in for a week and the results turned out to change a whole new colour and more breakage. We displayed our knowledge in our experiment on a science fair bored which Ms Wilton made, we took about a week to fully design our boards. 

Overall for our experiment the worst fizzy to drink are cola and cola no sugar cause they cause lot's of breakage, as well as rot in your teeth! both the lemonades didn't really have much of a change but the lemonade no sugar had a faint yellow shade along the inside of the shell, while the cola was turning a dark brown on the inside and outside. To show our results we made an observation about the colour and our variable was to change the type of fizzy. 

The hardest thing throughout science for me was to work well with my group, because I think I came across as bossy. I really enjoyed getting to see how our groups fair test came out with good proper results, I am glad we left the eggs in there for a week. I think me and my group did well because we all came together in the end and worked well.
