Lesson Title: Heavy Lifter
This lesson includes a series of activities that are based on robotics applications.
• Design and build a crane out of cardboard.
• Determine methods to reinforce the crane's arms so it doesn't collapse under a heavy load.
• Build a crank handle.
Lesson Activities and Sequence
Students make use of a crane here on Earth and apply how to use a crane in other places like the moon. At a lunar outpost, astronauts will need machines to build structures and move materials. One of those machines will be a crane. You've probably seen cranes lifting materials and moving them around a construction site. Cranes have a long arm, which holds a cable with a hook on the end. Whether they are on Earth or on the moon, cranes have to be strong to lift heavy loads without breaking.
