Station #2

At Station #2 we figured out what a radian was. We started by picking up our materials (paper, lid, markers, pipe cleaner, scissors, ruler, protractor and glue). We traced the shape of the lid onto a piece of paper and cut it out. We then folded it in half twice and made a dot in the center with a marker. After that we took the pipe cleaner, cut it to the length between the center dot and the edge of the circle, and used the ruler to draw a straight line from the center out to the edge of the circle. We then used the pipe cleaner to measure around the outside of the circle. Each time we came to the end of the pipe cleaner we would make a mark and move the pipe cleaners other end to that dot, moving around the circle. Once we went all the way around, we used the ruler and the marker to make straight lines from the center to the outside of the circle where the dots measuring the end of the pipe cleaner were located. There were six full sections and one small section. We glued the circle to a piece of paper and then the pipe cleaner to one of the lines we had created. We then used the protractor to measure the angle of one of the radians, assuming the others would be approximately the same.
