Our World: Simple Machines – Here and in Space
Simple machines are all around us and help make our work easier. When simple machines are combined, a compound machine is created. Learn about NASA's compound machine, the lunar crane, and the simple machines it contains to make work easier in Our World.
Discussion and Writing Prompts:
1. How do simple machines make work easier in everyday life and in space exploration? Describe at least two examples from the video (or your own life) and explain how they reduce force or change the direction of motion.
2. If you were designing a tool to help astronauts on the Moon or Mars, what problem would you solve and which simple machines would you include in your design? Explain how your design would make a difficult task easier in a low-gravity or space environment.
