4th Grade Science: Building Roller Coasters!
Our Saint John School 4th Grade classes were tasked with using what they had learned about energy transfer, force, motion, speed, and acceleration to design and test roller coaster models! These mechanical engineers designed, built, and tested their models. The requirements? Each model had to have at least one hill and the starting ball had to measure in at a dropping point of 75cm tall. Click on the link below to check out the video to marvel at their work!
