Picture of with wording STEM

Four 8th grade students spent the day on Friday at Joliet Junior college. Samuel C., Mohammad A., Sophia F., and Chrissy A. spent the first day of a two-day competition learning all about hydraulic and pneumatic power. Representatives from Caterpillar lead the instruction, demonstrating how to use the tools, before they set the students free to learn by doing.  Students built hydraulic lift and rotating machines in order to practice for their competition build in November.  Those four students will spend the next two months planning and building prototype machines to complete the task of moving a wooden dowel with only fluid power. Good luck tackling this challenge, team!
