Understandings
Students will understand…
-
Temperature is a measure of the average kinetic energy of a substance.
-
Heat is transferred from hot to cold.
-
Heat depends upon amount of material, type of material and temperature change that the material undergoes.
-
Any device has criteria to meet and constraints that can impact their design.
-
Energy can be calculated by: mass x specific heat x temperature change.
-
Power can be calculated by dividing the energy produced or used by the time in seconds.
|
Essential Questions
Students will keep considering…
- What criteria and constraints must be considered when building devices for a specific purpose?
- How does the study of heat energy, heat transfer, and heat transformations relate to everyday life?

Acquisition
|
|
Students will know…
-
Conduction transfers heat by contact.
-
Convection transfers heat by the movement of matter.
-
Radiation is the transfer of energy by waves.
-
Kinetic energy is the energy of motion of molecules.
-
Endothermic reactions absorb heat.
-
Exothermic reactions produce heat.
|
Students will be skilled at…
- Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.
- Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.
- Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample.
- Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.
