We did this because we want to find out how much chocolate chips were in the chocolate chip cookie. We even found more chocolate chips then what we predicted. Well we did used some tools. The tools were two toothpicks. Firstly when I just looked on top of the chocolate chip cookie I only found eleven chocolate chips. But when we started mining it. I found sixteen chocolate chips. So that was the evidence not just the predicted amount of chocolate chips. I learnt that it took a long time to find evidence.
