We live in a dynamic world where everything is in motion, or so it seems. But not everything is moving the same way. Some things move from one place to another. Other things rotate around and around. Still other things are stationary, stable for a time, balanced on a thin line between stop and go. Other objects move back and forth or vibrate. These are the global phenomena that students experience in the Balance and Motion Module. In this module, students will:
- Create and use representational models to demonstrate stable balanced systems.
- Plan and execute examples of stable balanced systems.
- Trace the changes in the position of an object over time.
- Combine materials that when put together can do things that they cannot do by themselves, and justify the selection of those materials based on their physical properties.
- Construct and evaluate toys that demonstrate spinning and rolling, and compare patterns of movement of objects.
- Design runways to control or change the motion of marbles.
- Communicate observations and compare stability and motion, using precise vocabulary.
- Plan and carry out investigations with sound.
- Analyze and interpret observational data.
