The Treehouse Detectives continue to search for a way to lift Jacob into the treehouse. They meet Dr. D at the circus to learn more about simple machines. Then they discover that NASA used pulleys to lift the space shuttle onto the back of an airplane. They talk with a NASA engineer to learn about pulleys. They believe this is definitely the way to go but think they need to do a little more research. They visit NASA's Langley Research Center in Hampton, Virginia, where pulleys are used to lift airplanes for crash tests at the gantry. Now they are certain that pulleys are the answer, but there are just a few little problems to overcome.

 Objectives: Students will
      Understand the principle of the Archimedes Screw.
