HS, Physical Science
Std 8.0:  Relate the law of conservation of energy to transformations of potential energy, kinetic energy, and thermal energy.
• Relating simple formulas to the calculation of potential energy, kinetic energy, and work
 

Lesson Plans:

What Is Work?
To show work (w) equals force (f) times distance (d) and the connection between work and potential energy, kinetic energy, and heat.

Potential Energy
The main objective of this mini teach is to introduce the concept of potential energy.  The students will recognize that potential energy is the ability to do work.

All Energy Is Not Equal
After a quick trip on the Web you've summarized the main types of fuels used in the United States, identified their energy content in BTU (British Thermal Unit) and the amount of carbon dioxide produced per unit of fuel.

Potential and Kinetic Energy
Students will observe and record the amount of work done by marbles rolling down a plane and more fully understand the relationship between potential and kinetic energy.

Kinetic Energy and Work
The main objective of this Mini-teach is for students to observe kinetic energy in balls of the same size but of different mass.

Give Me Energy
Students will be able to define, give examples of, and differentiate between potential and kinetic energy.

SUN-CENTERED PHYSICS
To use a coronal mass ejection (CME) to determine the relationship between position, average velocity and average acceleration and to analyze the motion of the coronal mass in terms of the forces acting on the body (Lesson 1).

Is Perpetual Motion Possible?
Students will build a model which demonstrates energy conversions (from potential to kinetic to thermal) and will apply these conversions to develop an understanding of the law of conservation of energy.

Specific Heat of Metals
Determine the specific heat (c) of several metals.
