Students will love you after you introduce this activity! Students use colored candies as weight to weigh down a bucket attached to a slinky. Make the buckets using old film cases and wire. Students measure the height of the bucket as they add weight. They are asked to record the data, graph the data, create a line of best fit, write an equation, and answer in-depth questions about the experiment. Take your students on a ride showing them the multiple ways to represent a function!
