1. Today is Monday, May 6, 2013 Homework: Packet due this Friday
Finish reading Chapter 14 by Friday
Chapter combine test IN ONE WEEK
Warm UP:
- What are some different forms of energy that you can think of? Discuss this with your shoulder partner.

2. Goal for Today
SWBAT demonstrate the ability to infer that energy can change forms and that energy can be in different forms by exploring kinetic and potential energy and other forms of energy.

3. Energy – the ability to do work or cause a change
Can change an object’s motion, color, shape, temperature or other qualities.
Some forms of energy….
Radiant (light), sound, chemical, nuclear, electrical, thermal, mechanical

4. Energy cannot be created nor destroyed.
What does that sound similar to? Law of conservation of mass
Energy can move from one object to another, changing forms
Fireworks – thermal  chemical  light and sound
Lamp – electrical  light

5. Potential and kinetic energy have an inverse relationship
Example: Roller coaster
As it gets higher: more potential, less kinetic (moves slower)
As it gets lower: less potential, more kinetic (fast movement)
Kinetic energy – energy due to motion (of waves, molecules, substances, and objects). Depends on it’s speed and mass
Includes radiant, thermal, mechanical, sound, electrical

6. Chemical and Nuclear energy are common kinds of potential energy
Potential energy – energy that is not causing any changes now but could cause changes in the future; stored energy
Chemical, nuclear, gravitational, electrical, mechanical
Mechanical and electrical energy can fall into either categories
Chemical and Nuclear energy are common kinds of potential energy
Chemical energy – energy of the electrons that form the bonds between atoms in molecules
The more electrons that are involved in a bond, the more chemical energy
Combustion is an example of potential chemical energy changing into other
Food
Nuclear energy - energy stored in the nucleus of an atom; it holds the protons together in the nucleus since their positive charges cause them to be naturally repelled from each other
Nuclear power plants use this to create thermal energy to create electrical

7. Closing it up….
Let’s see what Tim and Moby have to say about energy…..
