Hypothesis : The
faster the generator turns the more
electricity will be be generated.
Experiment: Place
the model wind turbine to a safe
place where blades can be turned without
interference.
Be very careful to never engage two gear sets at
once
and never force the blades to turn unless they
move
freely. Forcing
locked blades will ruin the model wind
turbine. The red
LED will glow when electricity is being
generated.
- Shift gears so that
the generator revolves three times
faster than turbine blades. Turn the blades at
10 rpm.
Does the
red
LED glow?
- Shift gears so that
the generator revolves at the same
speed as turbine blades. Turn the blades at 10
rpm.
Does the
red
LED glow?
- Shift gears so that
the turbine revolves three times faster
than the generator. Turn the blades at 10 rpm.
Does
the
red
LED glow?
Conclusions: Have
students discuss what they learned.
