Eighth graders were challenged to build the “slowest” roller coaster in science class using only four sentence strips and tape. Roller coasters were required to have at least 5 ramps, a tunnel, a trapdoor and a surprise.
This had to be accomplished in one class period along with running five trial runs with a marble. Once the time and distance were recorded, students solved for the speed of their marble on their individual coasters.
“This was the best lab of the year so far,” Brady Callens said.
Problem solving and engineering processes were definitely present in this activity along with a lot of fun!
