Water Wheel Generator—
Historical Inventions
Laboratory Kit
By: The Flinn Staff
Student understanding increases as they actually
see how energy from falling water is converted
into electricity. A water wheel and a simple AC
generator combine to construct a hydroelectric
generator that enhance students’ engineering
skills and allow full appreciation of a monumental
development from the Industrial Revolution!
Complete for 24 students working in groups of 4.

14-in-1 Solar Robot
Build a robot that is powered by the Sun! Learn
how solar energy can turn a small motor. When
that motor is connected to other materials,
the possibilities are endless. Instructions are
included to build 14 different robots. Construct
a turtle, crab, boat, beetle and even a zombie!
Enough materials included to build one robot at
a time. Includes an 82-page assembly manual with helpful diagrams.

Radiometer
It demonstrates the effect of infrared radiation with the spinning
of its vanes. Just set it in bright light or the sun and away it
goes. The hows and whys of solar motion are discussed in the
accompanying literature.

AP1948 Radiometer $16.05
Solar Bag
50-foot-long, 3-foot diameter, black plastic solar bag
holds over 350 cubic feet of air. Simply fill with air, tie
off the ends, and let the solar energy of the sun heat the
air inside the bag. In less than ten minutes, the bag will
rise into the sky. The solar bag rises so fast it must be
tethered to hold it down. Detailed instructions included.

AP4622 Solar Bag $23.95
Solar Furnace
This solar furnace is constructed with two major components—
a concentrator and a receiver. A 30.5-cm mirrored parabolic dish
is the concentrator, and the receiver is a copper container positioned
at the focal length (18.5 cm) of the parabolic dish. May
be used to boil liquids or melt various materials. Disassembles
easily for storage and comes complete with a Teacher’s Guide.

Build a Water Wheel—
Flinn STEM Design Challenge™
By: The Flinn Staff
In the first part of this activity, students build
an eight-bucket water wheel, choosing from the
materials provided. Each group then tests its
wheel, collecting data and making observations.
Next students brainstorm and decide how to make
improvements to their design. Variables, such
as the size, shape and number, of buckets are
considered. The improved water wheels are given
a final test to determine maximum power generated. A unique testing-station setup
eliminates the need for hot glue and allows for easy modification of the water wheels.
Complete for 30 students working in groups of three and two testing stations. A
source of running or falling water is required for each testing station.

Biofuels—Flinn STEM
Design Challenge™
By: The Flinn Staff
In this lab, students explore ethanol
production through the fermenta tion of
carbohydrates by yeast cells. First students
conduct a controlled experiment to investigate
the amount of carbon dioxide produced
through the fermentation reaction of yeast
with two different types of carbohydrates.
Students observe the amount of carbon
dioxide produced and determine the most
productive carbohydrate food source. Then students design and implement a method
to collect and quantify the amount of carbon dioxide produced. Integrate scientific
inquiry and engineering design and their application to challenges in our world with
this engaging activity.
Complete for 30 students working in groups of three.

Generating Electricity with Wind—
Flinn STEM Design Challenge™
By: The Flinn Staff
In the first part of this activity, students build a rotor
and blade assembly from the materials provided. Each
group’s prototype is tested by attaching it to a DC
motor (acting in reverse as a generator) connected
to a multimeter. A fan provides the wind. The highest
readings of volts and amps are recorded and the
maximum power output is calculated. Then, students
brainstorm and decide how to make adjustments
to enhance their design. The improved turbines are
given a final test for electrical output.
Complete for 30 students working in pairs and two testing stations. Multimeters and
support stands with clamps are required for each testing station and are available
separately. Box-type floor fans or turbo fans are also required for each testing station.
