Circles

Today we explored circles.  After reading “Sir Cumference and the first round table” and discussing the characters of Sir Cumference, Lady Di of Ameter, and their son Radius, we measured the radius and diameter of several circles.  We put the data into a table of values, and then did our first scatter plot of diameter vs radius.  We noticed that the points all lined up, showing a linear relationship.The next investigation we did involved licorice laces.  We measured the length, and then made tte licorice into a circle and measured the diameter.

We ate some licorice and repeated the process 5 times.

We put our data in a table
Then graphed it and noticed another linear trend.
