STANDARD 5.7 (PHYSICS): by Grade 4
Strands with Cumulative Progress IndicatorsA. Motion and Forces
- Recognize that changes in the speed or direction of a moving object are caused by force and that the greater the force, the greater the change in motion will be.
- Recognize that some forces can act at a distance.
• gravity
• magnetism
• static electricity
B. Energy Transformations
- Identify sources of heat and demonstrate that heat can be transferred from one object to another.
- Identify sources of light and demonstrate that light can be reflected from some surfaces and pass through others.
- Use devices that show electricity producing heat, light, sound, and magnetic effects.
- Show that differences in sound (loud or soft, high or low) can be produced by varying the way objects vibrate.
