Grade 8, Science
Std 10:  Differentiate between potential and kinetic energy.
• Stating the SI unit for energy (joule)

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.

Energy of Power Plants

Students will build a model turbine and identify conversions from potential to kinetic energy within the system.

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.

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.

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.
