Week 11: The Law of Conservation of Energy

(Before we start our new topic, we will continue this week with our guest speaker until Tuesday.)

Energy Vocab Foldable Assignment: Create more than one foldable (as shown in class) for your vocabulary words.
Page 442b Section 1-3 words
Page 472b temperature, heat, conduction, convection, radiation, conductor, insulator, change of state, thermal expansion, refrigerant, heat engine

This week's topic sounds like another law we learned just a few weeks ago. Do you remember that law? That's right! The law of conservation of matter states that matter can neither be created nor destroyed during a chemical reaction, but can be transformed into a new substance.  The Law of Conservation of Energy says:  

Energy can neither be created nor destroyed, but transformed into another type of energy.

Let's first look at the specific types of energy and then talk about how energy is conserved.

Two Main Types

• Kinetic - energy in motion
• Potential - stored energy (a build up of energy)

Types of Energy (these fall under either of the two main types)

• Gravitational Potential Energy
• Elastic Potential Energy
• Sound Energy
• Light (aka Radiant or Electromagnetic) Energy
• Thermal (or Heat) Energy
• Mechanical Motion Energy (don't worry about formulas here)
• Electrical Energy
• Chemical Energy
• Nuclear Energy
• Magnetic Energy

To help us remember some of the different types of energy, we may get to meet Mr. Cents!

How does energy transform from one to the next? Before I answer that think about the energy that is necessary to complete these activities:

1. toasting bread
2. watching tv
3. walking the dog
4. skiing
5. bowling
6. talking on the phone

So what energy is necessary to make these activities happen? Be prepared to discuss the answers in class.
