4 Major Types of Energy • Electrical—energy is transferred through electricity.
– Examples??
• Electromagnetic—energy is transferred through waves. (the light from a computer screen)– Examples??
• Mechanical—being pushed or pulled – Examples??
• Thermal—energy transfer when a warmer object is in contact with a cooler object. – What are the three types?
Thermal Energy can be….
• Radiation—thermal energy transferred through electromagnetic waves; not touching
• Conduction—thermal energy is transferred when 2 or more materials are in direct contact with one another
• Convection—thermal energy is transferred in circular currents through air, water and other fluids

Energy Connections Sheet
We have already completed this sheet but this is a great review for our test. • Complete this entire sheet without looking
back to the one already in your notebooks. • Use the definitions to help • When you are finished, use the sheet already
in your notebook to self check your answers• 10 minutes…Good Luck!
Energy Paired Reading
• You and your partner will receive the same paragraph to read BUT there is a trick.
• One of you will be missing some words and the other person will be missing different words.
• It is your job to read together and fill in your paragraphs as you go.
For example…• Original Sentence: – The brown dog crossed the street.
• Student 1 Sentence: – The brown _____ crossed the _____.
• Student 2 Sentence: – The _______ dog _______ the street.
• Now as you read together you will be listening and filling in the blanks. 10 minutes…Good Luck!
Review!
• We are going to play a quick review game!
Rules: • You may use your notes. • You must be silently raising your hand. • You will win a piece of candy each time you answer
correctly. • Do not yell answers out or you will be disqualified
from the game.

Raise your hand if you know….
List the Electromagnetic Spectrum in the correct order:
Radio, Microwaves, infrared, visible light, ultraviolet, x-ray, and gamma ray
Raise your hand if you know….
What is the longest wavelength?
Radio Waves
• have the longest
wavelength and low energy • carry radios, TVs, and
cell phones signals
Raise your hand if you know….
What is the shortest wavelength?
Gamma Waves• Shortest wavelength and
highest energy • Most dangerous
Raise your hand if you know….
What is the visible light spectrum?
ROY G. BIV
Raise your hand if you know….
Which color has the longest wavelength?
RED
Raise your hand if you know….
Which color has the shortest wavelength?
Violet
Raise your hand if you know….
What are gamma rays used for?
Gamma• Used in medical treatments:
can kill cancer cells but can also kill living cells (hair falls out)
Raise your hand if you know….
Which is the only wave we can see?
Visible Light Waves
