Week 1

 

  • Introduction to Alternative Energy
    • Different kinds of Alternative Energy
      • Solar
        • Solar panels
        • Harnessing energy from the sun
      • Wind
        • Wind mills
      • Water (hydro[electric])
        • Dams
        • Water wheels
      • Mechanical
        • Man powered hand crank
        • Stretched rubber band upon release exerts energy
      • Geothermal
        • Harnessing energy from inside the heat of the earth
      • Kinetic
        • When an object has energy in motion
      • Potential
        • When an object has the energy stored to be moved
      • Nuclear
        • Usually created from a bomb, i.e. Hiroshima, Atomic Bomb
      • Biomass
        • Burning wood
        • Animal defecations
    • In depth . . .
      • Gears
        • Number of teeth and diameter size
        • Gear ratio and relationship
        • Same size gears, no reduction
        • Bigger gear on motor + smaller gear = more energy
        • Smaller gear on motor + bigger gear = less energy
        • How it effects the speed and effectiveness of the model
      • What are you powering?
        • Depending on what you choose to power, you will have to use the appropriate amount of energy to produce enough energy to produce an equal output (equal input equals equal output)
  • Presentation of models
    • Hydroelectric
    • Play pump
    • Wind turbine/mill
    • Mechanical/storing energy
  • After presentation, create and experiment with own models
  • Manipulation and explanation of the different models
  • Presentation of what each person did, individually, not in pairs
  • Questions cross referencing to real life and real world problems
    • How can this be used in real life?
    • What can this be used for in real life?
    • How can this solve real world problems we have today?
    • What different real world problems can it solve today?
    • Is this more efficient? Why or why not?
    • What are the pros? The cons? Drawbacks?
  • Circle up
    • What have you learned?
    • What're the problems that you encountered?
    • How did you overcome these issues?
    • If you could change one thing or go back and modify 1 thing, what would it be?

 

  • More lessons of gear ratio and more examples, samples
  • Information and theory
  • Motor powering a motor
  • More information about AE versus just LEGO building
  • Putting LEGOs away, giving explanation, then pulling them out
  • People who don't know what to do can make replica or miniature
  • People who don't know what to do can come up with a concept, drawing, sketching, relate to real life
  • Figure out steps on how to get to the final project or solid concept
  • Clearify that it's a motor, a power source, and a generator
  • Be specific and explain what the power source is
  • Mechanical energy - any energy that is mechanically powered, hand, water
  • Potential/kinetic energy - energy that is stored, and then energy released
  • Extra examples for them to build upon different and varying ideas

 

Week 2

  1. Greenhouse visit (Huntington)
  2. Jeopardy
  3. Different interactive games
  4. Instructables.com solar panels
    1. Projects from solar panels and games
  5. Making a charger using a solar panels (project idea)

 

Lesson Plan Overview for Week of Alternative Energy 2

 

Have new youth teachers create more efficient energy models using less energy and generating more energy and measure the amount of energy used. The youth teachers will be able to use multimeters and have them experiment with the solar panels and how much energy the solar panels absorb from the lights and other resources that emit light energy.

 

     1. Youth Teachers will be introduced to multimeters and for 5-10 minutes will measure the voltage from solar panels, motors, and examples we set out

     2. Youth Teachers will have 20-30 minutes to sketch and build their new, more efficient energy models

     3. Youth Teachers will then use multimeters to measure the amount of energy the energy model produces

     4. After measuring the amount of energy their models produce, Youth Teachers will make their energy models more adequate

     5. If there is more time, we will discuss why some models worked better than others and/or why they were more sufficient
