This worksheet was created to go along with a popular Rollercoaster Engineering lesson that I do in my STEM elective classes. I use this activity to introduce my students to the Engineering Design Process, but it can also be used as review. To make the rollercoasters, you will need:Insulation foam tubing, cut in half (you can buy this cheaply at Home Depot)Marbles (representing your rollercoaster car or person riding your rollercoaster)Cups (to catch the marble at the end of the coaster)Masking
