Product Description
In this fun, hands-on activity students conduct an experiment to determine how many pennies a piece of spaghetti can hold. After recording their results, students use their calculator to determine the line of best fit, the correlation coefficient, and the rate of change. Students must also interpret the slope and y-intercept in the context of the experiment.

Supplies Needed:
• Cup for each group with a hole punched in either side and a string tied through the holes. I use plastic Tupperware containers with holes drilled through the sides and paper clips strung together instead of string.
• 28 pieces of spaghetti per group. I use angel hair instead of regular spaghetti to make the experiment go faster.
• 150 pennies per group.
• Copy of the handout for each student.

This is the lesson that goes with the spaghetti experiment:
