Today we did a PI day activity! Today's date is 3/14 so it's "Pi Day". We discussed the digits of pi. It has an infinite number of digits and has no pattern to it, so it's considered an irrational number. We discussed that Pi is found by taking the perimeter of a circle, also known as circumference, and dividing by the diameter. Andrew and I started with his water bottle. We used a string and ruler to measure the distance around the water bottle (circumference). Then we measured the distance across the bottom (diameter). We recorded our findings. Then we divided the two numbers and got 3.09. We compared it to Pi's rounded value of 3.14. We discussed why our answer wasn't exact. Andrew understood it's almost humanly impossible to get a perfect PI, only because it's difficult to get accurate readings. We are using our fingers and eyeballs and since we are not robots/computers, our findings could be off by fractions. We used this process to measure the clock, and a plate we found in the cafeteria. Each time we got pretty close to pi.
