Annotating Competing Designs • Closely examine and annotate each design to record your observations and questions.
Note the ways that the designs are different and record your ideas about how the
differences will affect the speed of the roller coaster car.
Think about the key concepts you learned while investigating the spacecraft problem,
which are posted on the classroom wall.
.
After you have considered and annotated each design, discuss the following question with your
partner
Which design do you think will launch the roller coaster car the fastest?
