This lesson builds on research of how real world data investigations can be used to engage students to learn key concepts in data science and statistics. The lesson uses a free online data visualization tool (CODAP) and a dataset of 635 roller coasters from US amusement parks in operation in Spring of 2020. Variables like top speed, material used, seating arrangement, length of track, and height quickly engage students in making sense of the data and using their real world and scientific underst
