Explain

Directions

1. For the explain portion of the section, work through each slide (one slide for each of the 6 forms of energy).2. On each slide you will find #1, #2, and #3 talking and discussion points. Follow the numbers to work through each slide in a logical progression of:

#1 Introducing the form of energy#2 Giving an example of the form of energy#3 Leading a student discussion about other examples of that form of energy.

1. Definition: Mechanical energy is the energy that an object has because of it's motion or

position. Mechanical energy can be kinetic (in motion) or potential (waiting energy).

3. Student Discussion: Why are these pictures examples of Mechanical Energy? Can these pictures be examples of any other forms of

energy?

2. Teacher Explanation: A roller coaster is an example of Mechanical energy because a roller coaster only has energy while it is in motion. Think about how EVERY roller coaster starts. The top of a large ramp!

1. Definition: Chemical energy is energy that is stored in chemical compounds (atoms and

molecules). The energy is released when there is a chemical reaction.

2. Teacher Explanation: This girl is eating a peach. While there is no reaction taking place instantly, her body with eventually break down by a chemical reaction and use the nutrients for energy.

Chemical Energy3. Student Discussion: Why are these pictures

examples of Chemical Energy? Can these pictures be examples of any other forms of

energy?

1. Definition: Electrical energy is energy that is available through a conductor.

2. Teacher Explanation: In this picture Electrical energy or electricity is made available to homes and businesses by being carried through the power lines. Power lines are an example of a conductor.

Electrical Energy3. Student Discussion: Why are these pictures

examples of Electrical Energy? Can these pictures be examples of any other forms of

energy?

1. Definition:Sound energy is the movement of energy through waves.

2. Teacher Explanation: Dolphins communicate through sonar or sound waves under water. Using the nasal sacks in their heads they send out rapic clicks in front of them. The sound waves moves through the water, bounces off the object they are investigating, and is reflected back to the dolphin. When they receive the information their auditory nerves create an acoustic picture of the object (www.pbs.org)

Sound Energy3. Student Discussion: Why are these pictures

examples of Sound Energy? Can these pictures be examples of any other forms of

energy?

1. Definition: Heat energy is the energy that comes from heat. Heat energy always flows from the warmer object to the cooler object therefore

warming the cooler object.

2. Teacher Explanation: While a toaster uses electrical energy to power it, the heat energy from the hot coils in the toaster warm up the cold toast that you put in it and after a short amount of time you have warm toast!

Heat Energy3. Student Discussion: Why are these pictures examples of Heat Energy? Can these pictures

be examples of any other forms of energy?

1. Definition: Light energy is energy that comes from light. Light energy is made up of tiny particles that travel in waves, you cannot see the waves but you can see the light. Light travels until it hits an

object and is either absorbed or reflected.

2. Teacher Explanation: The sun is a prime example of light energy. It is a natural source of light and it's rays travel all the way to the earth's surface. The suns light energy can even be converted to electrical energy through solar power!

be examples of any other forms of energy?
