Build your model ballista. Then construct two other types of catapult - the onager and trebuchet - designed such that they store the same amount of energy as your ballista. Field test all three to determine which throws a golf ball farthest. Will the winner be the weapon from the Hellenistic (ballista), late Roman (onager), or medieval era (trebuchet)? You may be surprised!

Start your project on fixed-wing flight the way the Wright brothers did: by building a wind tunnel. Use it to test different wing shapes at varying angles of attack, exploring the phenomena of lift, drag, and stalling. Your goal is to design a wing appropriate for a low-speed model plane, powered only by a few strands of rubber and flying without remote control.
