To the rescue on land or sea! Put out the fire! Deliver heavy cargo! Design a 3-D model helicopter and discover how they fly.
Helicopters were first designed in the 1930s for military use. They were widely used for the first time in the Korean War. Flying a helicopter takes hours of training and great skill.
Have you noticed that helicopters can fly forward, backward, sideways, straight up, and straight down? They can also hover and stop in mid air. Find out more about their unique maneuvering capabilities. Students look at pictures and view films to learn about how helicopters fly. Read about the lifting force provided by the main rotor. Why is the tail rotor important to keep the helicopter flying straight?
Students choose a helicopter model to make. What work will it do? Then use their imagination along with these ideas to make a realistic replica.
Crumple aluminum foil to create an armature (lightweight form). Shape the foil into a helicopter body, tail boom, and drive shaft for the main rotor.
Cover the foil with a layer of brightly colored Crayola® Model Magic. Use two or three colors and mix them to create new hues. Blend in white Model Magic for tints. Air-dry the helicopter at least 24 hours.
On white paper, use Crayola Twistables to draw and color the helicopter’s main rotor and tail rotor. Use Crayola Scissors to cut them out. Push a toothpick through the main rotor. Attach it to the drive shaft. Push another toothpick through the tail rotor and attach it to the end of tail boom.
Draw and cut out a cockpit. Students show themselves as the pilot! Use Crayola School Glue to attach the cockpit to the front of the helicopter. Air-dry.
Twist together two or three chenille sticks to create sturdy landing skids. Insert them into the bottom of the helicopter. Glue them to the body of the helicopter. Lay the helicopter on its side while it air-dries.
