Sally and Juan's science teacher has directed the class to build a paper airplane. The challenge is to build an airplane that flies the farthest distance. The students have two days to design and test their planes. The assignment will end with a "fly-off". Sally and Juan built their first plane.

The plane flew, but did not get very far. Next they tried to change the way they threw the plane. After many tries, their plane flew an average distance of 35 meters.
