Competency Goal 6: The learner will conduct investigations and examine models and devices to build an understanding of the characteristics of energy transfer and/or transformation.

Objectives

6.01 Determine how convection and radiation transfer energy.

6.02 Analyze heat flow through materials or across space from warm objects to cooler objects until both objects are at equilibrium.

6.03 Analyze sound as an example that vibrating materials generate waves that transfer energy.

• Frequency.
• Amplitude.
• Loudness.
• How sound travels through different material.
• Form and function of the human ear.

6.04 Evaluate data for qualitative and quantitative relationships associated with energy transfer and/or transformation.

6.05 Analyze the physical interactions of light and matter:

• Absorption.
• Scattering.
• Color perception.
• Form and function of the human eye.

6.06 Analyze response to heat to determine the suitability of materials for use in technological design:

• Conduction.
• Expansion.
• Contraction.

6.07 Analyze the Law of Conservation of Energy:

• Conclude that energy cannot be created or destroyed, but only changed from one form into another.
• Conclude that the amount of energy stays the same, although within the process some energy is always converted to heat.
• Some systems transform energy with less loss of heat than others.
