"The Knots Lab" is a hands-on experiment that can be used when teaching linear functions; primarily when discussing lines of best fit.  Students are given a rope (3-5 feet in length) and a ruler.  Students begin by measuring the rope.  Students then tie knots in the rope, and after tying each knot, measure the resulting length of the rope.  After constructing a scatter plot of their data, students are asked a series of questions where they must use their data and regression equation to answer.
