Great Coasters International Engineer, Anya Lehrner, took the time to Skype with us about roller coaster design. As part of our force and interactions unit, the students will be designing and building their own roller coaster amusement park. Anya gave them advice and let them know how force plays a role in roller coasters. She also let students know how they design, build and test roller coasters to make they are safe. Thank you, Anya!
