4.1 Objectives
• Define energy
• Describe the Law of Conservation of Energy
• Describe the different types energy and how they change forms

Energy is the ability to do work. It is vital to all life on Earth. –Potential: stored energy
–Kinetic: energy of motion

Law of Conservation of Energy
•Energy is never created or destroyed–Changes from one form to another

Law of Conservation of Energy
• How much energy passes from one level to the next???
• What happens to the rest of the energy?
• Does it disappear???

There are many different types of
energy!

What is the energy transformation?
• Battery turns on calculator
• Burning paper
• Plug in a fan to turn it on
• You put gasoline in your car to make it move

Energy changes forms—we can use certain resources to give us
energy from an electrical socket…

Before we get started, the basics…
• Electricity: the flow of electrons
• Turbine: have rotating parts
• Generator: converts mechanical energy to electrical energy

Stations• Let’s do one
example of energy transformation together…
• 4 stations– 4 minutes each

Electricity Reflection Questions1. What form of energy are we always ending with?
2. Look at wood, coal and oil examples: what type of energy are we starting with?
3. Look at water and wind examples: what type of energy are we starting with?
4. How are the water and wind examples similar from wood, coal and oil?
5. How are the water and wind examples different from wood, coal and oil?
