Energy Lessons 1 & 2

Energy Warm Up

​GOALS

​STANDARDS

• Understand & apply the Law of Conservation.

  Given an example scenario, explain what kinds of energy are present and what transfer and/or transformation occurred.

  Apply prior knowledge of Potential and Kinetic Energy more specifically to our new energy content within this unit.

• 7.PS.3: Energy can be transformed or transferred but is never lost.​

• 7.PS.4: Energy can be transferred through a variety of ways
