Do now!Can you write the title
Types of Energy
in your book?
Do NOT touch the experiments on your table
DO NOW!
Mini-book
In your mini book I would like you to write one fact/piece of information about energy on each page of the mini book.
What is Energy?
“The capacity to do work”
Not a very good definition!
Types of energy
Energy can take many forms;
Heat
Unlucky dog
Kinetic (movement)
Chemical
Gravitational potential
Elastic/strain
Types of Energy
Heat Chemical
Light Gravitational
Sound Elastic/strain
Kinetic Nuclear
Electric

The Law of Conservation of Energy
The Law of Conservation of Energy
Energy can be changed (transformed) from one type to another, but it can never be made or destroyed.
This means that the total amount of energy in the Universe stays the same!
Energy Flow diagrams
We can write energy flow diagrams to show the energy changes that occur in a given situation.For example, when a car brakes, its kinetic energy is transformed into heat energy in the brakes.
Kinetic heat
Other examples
When a rocket launches.
Other examples
When a rocket launches.
Chemical kinetic + sound + heat gravitational
Energy Circus
Around the room are 12 examples of energy changes (some simple, some a little more complicated!)
For each example I want you to write the name of the apparatus and the energy flow diagram for that experimentYou will move to the next experiment at the appropriate signal.
Go!
