In these activities, students look at attributes that vary from coaster to coaster, attributes that make each scream machine uniquely thrilling.
Students use a Web site to view photos of roller coasters from around the country. Based on the pictures, students predict which coaster is faster, which is higher, which goes farther, and which takes longer. They look up data on another Web site to check their predictions. Finally, students evaluate their estimates of speed, height, etc., to see whether their estimation skills improve with experience.
