Transcript Wind Power Presentation

OBJECTIVES:
HOW TO MANIPULATE WIND ENERGY
• Two ways glaciers
move
ENERGY
RENEWABLE ENERGY SOURCE
Energy source we can use
over and over again
Is the ability to do work
NON-RENEWABLE ENERGY SOURCE
Energy source we are using up
and cannot recreate in a short
period of time

POWER = VOLTAGE x CURRENT
LET THE GAMES BEGIN
• Competition to see which group can build the
most powerful wind device
• Each group will discuss their plan for designing
a wind-turbine:
– Thickness of paper
– How much tape
– How much clay
– Length of straw
– Shape of the blade
WINDMILL DESIGN & MATERIAL
SELECTION
• List at least 3 factors that make a wind-powered
device a good alternative energy converter
• Illustrate the shape of your windmill blades. What
are the benefits of the shape you selected?
• Which thickness did you select for your blade? Why?
• How will you know if your blade design is effective
and efficient?
TRIAL AND ERROR
• Describe the features of the most efficient windmill.
List at least 3 features
• What one variable will you change about your
windmill to improve the efficiency of your model?
• Did the changes you made improve the efficiency of
your model?
• Sequence the cutting of the template to make it easier
– Show students the one I built
• Wrap straws with layer or two of tape to stop blades from
sliding off one end (other end will have clay)
• Bring handful of leads and jumpers
• Make sure students test at 3 different speeds
• MAKE EXCEL FOR STUDENTS TO INPUT THEIR I,V,P …
• Make sure blade tips are not bent
