Question My testable science fair question is: Can you accurately measure pi through scientific experiments? I will conduct four separate scientific experiments throughout my project. My hypotheses for Hypothesis these experiments will vary greatly. My first experiment will be finding several large circles in our environment, then pacing off the circumstance and the diameter. I will then calculate pi by dividing the measured circumference by the measured diameter. My hypothesis for this method is that it won 't be very accurate and only round pi to a whole number (3) because of the inaccuracies of heel to toe measuring. In my second experiment, I will throw cylinders on the floor marked with tape strips. This method uses the random location of the cylinders and calculates pi by seeing how many cylinders cross over lines. This experiment is a variation of Buffon 's needle, one of the oldest problems in the field of geometry. I expect this method to calculate pi between a range of 3.1 to 3.2. because although this experiment is supported scientifically, it 's still a game of chance. In the third experiment, I will program a computer to repeat my throwing cylinders experiment repeatedly to get more accurate results. I believe that this experiment will be just as accurate as my second experiment because I expect after 200 repeats the results won 't get much more accurate. My fourth experiment will be using regular polygons (triangles, squares, and octagons)
