An experiment was conducted to determine which type of fruit attracts the most fruit flies. Equal sized pieces of apple, pear, and banana were placed in separate containers at different areas around the school.

They had two independent variables

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. Whenever they tested the plane, it would take a nosedive into the floor. They changed the design by reshaping the nose of the plane and adding some weight to the tail. 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. Sally and Juan's trial and error airplane design could be described as in the technological design process.
