…a good balance of science and fun!
- Simple machines help objects to move.
- Simple machines and mechanisms make life easier and/or more enjoyable for humans.
Curriculum Connection: Grade 3: Structures and Mechanisms Continue reading
At this level, students are expected to understand a functional structure and identify the various processes and components of a system (e.g., robot, front-end loader/backhoe). The students should also be able to calculate the mechanical advantage (MA = force needed without a simple machine divided by force needed with a simple machine) of various mechanical systems (e.g., a robotic arm transfers force through the fulcrum or a simple fixed pulley system redirects the effort force). This activity will provide a concrete example of how a robotic arm functions, thus describing systems that could potentially improve the productivity of various industries (e.g., robotic systems have increased the rate of production in factories that assemble the fine parts of wristwatches).
