Planning and Carrying out Investigations
Crosscutting Concepts
Energy and Matter
Knowledge
Students know:
- Qualitative measure of energy (e.g. relative motion, relative speed, relative brightness) before the collision.
- Mechanism of energy transfer.
- Energy can transfer between colliding objects.
- Energy can transfer to the surrounding air when objects collide resulting in sound and heat.
Skills
Students are able to:
- Plan and carry out an investigation to determine changes in energy that occur when objects collide.
- Identify the evidence to address the purpose of the investigation.
- Collect the data.
- Use data to provide evidence that energy is present whenever there are moving objects, sound, light, or heat and that it can be transferred from place to place.
Understanding
Students understand that:
- Energy can be transferred in various ways and between objects.
Vocabulary
- collide
- relative motion
- relative speed
