"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.
