What is Energy?

What is energy video

Forms of Energy

Potential (stored energy & the energy of position)
  • Chemical energy - the energy stored in the bonds of atoms and molecules. Food, wood, coal and petroleum are examples.
  • Nuclear energy - the energy stored in the nucleus of an atom - the energy that holds the nucleus together. Example: Uranium atom
  • Stored Mechanical energy - energy stored in objects by the application of force. Compressed springs & stretched rubber bands are examples.
  • Gravitational energy - the energy of place or position.

Kinetic (The motion of waves, electrons, atoms, molecules & substances)
  • Radiant/Light - electromagnetic energy that travels in transverse waves. Solar energy is an example.
  • Thermal/Heat - the internal energy in substances - the vibration or movement of atoms and molecules in substances.
  • Motion - the movement of a substance from one place to another.
  • Sound - the movement of energy through substances in longitudinal waves.
  • Electrical - the movement of electrons.

Energy Transformations


Laws of Convervation:
  • Energy cannot be created
  • Energy cannot be destroyed or "used up"
  • Energy can change from one form to another

Wasted Energy - When energy changes form, some thermal energy is always released. For example, a lightbulb converts some electric energy into radiant energy. However, the lightbulb also transforms some electric energy into thermal energy. This is what makes the lightbulb hot. Some of this thermal energy moves into the air and cannot be used. Scientists often refer to thermal energy that cannot be used as waste energy. Whenever energy is used, some energy is transformed into useful energy and some is transformed into waste energy. For example, the chemical energy in gasoline makes cars move. However, most of that chemical energy ends up as waste energy—thermal energy that moves into the air.

Two Main Types of Energy

  1. Potential - Stored energy & the energy of position
  2. Kinetic - The motion of waves, electrons, atoms, molecules & substances

Heat Transfer Photos
  • Look at the Heat Transfer Photos from the link above.
  • On a separate sheet of paper make a list of what all the pictures have in common. (minimum of 3 things)
  • On that same sheet of paper write down at least one way each picture is different from the others.
  • All of these photos show heat transfer in a different way. Can you come up with 3 ways heat is being transferred based off the pictures you looked at. List your 3 ways on your paper.

  • What makes you think heat is moving? Is there any evidence that you see showing heat transfer?
  • Where does the heat come from and where does it go?
  • What questions do you have about this situation?

Sources of energy

Renewable - energy resources that replenish themselves through natural processes within a human lifespan.
  • Hydro (Water)
  • Wind
  • Solar
    • Passive
    • Active
    • Photovoltaic Cells
  • Geothermal
  • Biomass
    • Wood
    • Waste - Trash Incineration, Landfill Methane
    • Agriculture - Corn, Soybean, Animal & Plant waste

Non-Renewable - energy resources that are finite or take millions of years to replace.
  • Nuclear
    • Uranium
  • Fossil Fuels
    • Coal
    • Natural Gas
    • Petroleum - Oil, Propane, Gasoline, Diesel

Top 10 Future Energy Sources

Energy Conservation & Efficiency

Energy Conservation - Any behavior that results in the use of less electricity.
Examples:
  • Turning off the lights when you leave a room
  • Turn your thermostat down 2 degrees
  • Only wash full loads of laundry
  • Walk places instead of driving your car

Energy Efficiency -The use of technology that requires less energy to perform the same function.
Examples:
  • Use LED or CFL light bulbs
  • Buy Energy Star appliances
  • Install energy efficient doors

Day 1: (Tuesday, Sept. 22nd) Create your Energy Team Wiki page under your class, below.
  • Decide on a Team Name
  • Post a photo of your team along with your team name to your wiki
  • List the team members and the strengths each member brings to your team
  • After each person's name:
    • Make a list of what you already know about Energy.
    • Make a list of things you want to find out about Energy.

Day 2: (Wednesday, Sept. 23rd) What are the different forms/types of energy?
  • Go to each link below to answer the question above.
  • Take notes while researching. Keep your notes concise and be prepared to share ideas in class on Thursday.

Day 3 & 4: (Thursday & Friday, Sept. 24th & 25th) As a team, take the notes you took from the links and during class to create your own visual map about the different forms of energy. (This chart must be digital. Use any program you would like to create it.)
Your map must include:
  • Forms of energy as the title
  • The two types of energy and a brief definition.
  • The forms of energy and a brief definition.
  • 2 examples of each form of energy. Each example must include a brief written description & picture.
  • You can make your map in any program (ex. word, inspire, popplet - username: tb03bps@birmingham.k12.mi.us password: goblue)
  • Post your map to your team wiki
