EXPERIMENTS
1
Producing power with a hydropower station (rotation)
Build the following experiment as shown below:
Connect the generator and LED using the alligator
clips as shown:
+
In this experiment we turned the crank by hand and the LED lit up. I.e. we
were able to generate energy.
This works the same with a hydropower station. The direction in which
water flows is converted into a rotation. This rotation then drives a generator,
which then produces electrical power, hence e.g. supplying electricity for a
house. Hydropower stations can be found in rivers (river power plants) or e.g.
Hydropower station
in the Alps at dammed lakes (reservoir power stations).
Now turn the crank in the direction shown!

Generating electricity by solar plant
Build the following experiment as shown below:
Connect the solar module and
LED using the alligator clips,
as shown:
We were able to make the LED light up by illuminating the solar cell.
This is the same concept as a solar plant (also called photovoltaic
system). Sunlight is converted to electrical power.
Now illuminate the solar cell
21
with a torch or sunlight!
Solar plant
Here, remember the more sunlight strikes the solar cell, the more energy
is produces. Wherever there is a lot of sunlight, photovoltaics can easily
and reliably generate energy, silent and environmentally friendly.

Generating electricity by wind power
Build the following experiment as shown below:
Connect the windmill using the alligator
clips as shown:
Now blow hard into the blue propeller!

Wind power plants
What did you learn from the experiments?
Environmentally-friendly energy can be generated by:
Hydropower stations
2
The LED lit up after we blew hard into the propeller. In large wind power
plants wind drives the wind turbine blades which in turn generate a
rotation of the hub.
This rotation is then converted into electrical power. This technology is
particularly excellent in windy areas and produces environmentallyfriendly energy.

How a generator works:
Build the following experiment as shown below:
Connect the generator and the motor using
the alligator clips as shown:
Now turn the crank in the direction shown!

2
Now turn the crank again in the direction shown and see what happens!
Once the generator crank is turned, the motor begins to turn. So we were able
to produce power using the generator. If we change the direction of rotation
of the crank, the motor will also turn, but this time in the other direction. The
rotational direction of the motor is entirely determined by the rotational
direction of the crank.
Producing power with a generator, how it works: A generator converts
rotation (mechanical energy) into electric power. This for example occurs
when a magnet is moved inside a coil (wire wound several times) (see
Generator
image). The electric power generated by the motion can e.g. make a lightemitting diode light up:

TIP:
You can also try this experiment:
Wind power makes the generator turn – connect the propeller to the generator and blow hard!
Solar power allows the generator to turn – connect the solar module to the generator and aim the solar
module at the sun!
