Energy and Matter
Knowledge
Students know:
- Energy is present whenever there are moving objects, sound, light, or heat.
- The transfer of energy, including the following:
- Collisions between objects.
- Light traveling from one place to another.
- Electric currents producing motion, sound, heat, or light.
- Sound traveling from one place to another.
- Heat passing from one object to another.
- Motion, sound, heat, and light causing a different type of energy to be observed after an interaction.
- Heat is produced in many ways.
- Heat can move via conduction.
- The properties of different objects cause them to be able to absorb, reflect, and/or conduct energy.
- Electric currents pass through a circuit.
Skills
Students are able to:
- Collaboratively plan and carry out an investigation that converts energy one form to another.
- Identify the phenomenon.
- Identify the evidence to address the purpose of the investigation.
- Collect the data.
- Construct an explanation using evidence about heat production.
- Develop a model demonstrating that different objects can absorb, reflect, and/or conduct energy.
- Develop a model demonstrating electric circuits.
Understanding
Students understand that:
- Energy can be transferred in various ways and between objects.
- Heat energy can be produced in many ways.
- The properties of objects, e.g. ability to absorb, reflect, or conduct energy, relate to their function.
- Electric energy can be transferred through circuits.
