Rot Ya Teeth!

For a few weeks now, our class has been doing Science. We've been learning about "Fair-testing". Fair-testing is where you have an experiment and when you fair-test it, you're keeping everything fair, keep it equal. But then we did Variables. A Variable is something you change or you vary. Our group (Mikaela, Felix and I) and every group had to make six variables up.

Our group was doing the experiment "Rot Ya Teeth". We used egg shells as teeth and got different types of fizzy drink: Cola, No sugar Cola, Lemonade, No Sugar Lemonade.

But before we made the experiment, we had to had to make 3 things we could measure of the end result. Out of the things we could measure, we chose how rotten/dark the egg shell had gotten in colour. Out of our six variables, we chose to change the types of drinks.

After we started our experiment, we left our cups of eggs in fizzy up in the windowsill for a week. When we got them down after the week we made a science board. Every group had to make one about they're experiments. We had to put all the information in, graphs or diagrams, all the variables and measurements. It took days, but on the day of the science fair, our group finished, and our board looks great.

The results were, cola was the most rot and dark in colour. The next was cola no sugar. Then lemonade, then lemonade no sugar. But lemonade no sugar's drink in the cup turned pee yellow, for some reason I don't know of. The cola's drinks went kinda milky and lost some colour. Lemonade stayed the same.

But before all that, we started small. Miss Wilton gave us little containers and we got to choose our groups. We put water in the containers then went outside and put different amounts of Barroca into the containers. That was when we learnt what a fair-test was. After that we did blood splatter. Miss Wilton made fake blood, and we measured it on the same surface. But we measured how big the splat was using the same amount of blood but from different distances, the different distances was the variable. Then we learnt how to graph our fair-tests. This was all so fun, but then we got into our own experiments, which all the information is in these other paragraphs.

Here are the photos of our science board.
