Hand-Cranked Generator NGSS

SKU #GEN-100
Availability: In Stock
Qty.
This hand-held crank generator produces up to 12 volts of DC electricity.

Description

This hand-held crank generator produces up to 12 volts of DC electricity. It can be connected to an external circuit or used independently as a flashlight with the included bulb. Housed in tough transparent plastic, all of the components can be easily observed. In addition, other devices can be easily connected to the black and red screw terminals on the front of the generator without the need for any special adapter that could be quickly lost. When compared with similar products costing more than twice as much, we overwhelmingly preferred this one for its simplicity and usability.

  • Size: 105 mm x 50 mm
  • Avg Volt. (no load, fast) : 12 v DC
  • Avg Volt (no load, moderate) : 6.5 v DC
  • Current: 2.3 amp @ 7.5 v (3.2 ohm load)
  • Weight: 150 gram
  • Lamp: 3.2 ohm, 6.3 volt

Making Energy Generation Understandable
Review star icon Review star icon Review star icon Review star icon Review star icon Apr 2, 2014
In teaching my grandchildren about the energy being generated all around us and not taking it for granted I was able to show them the principle behind electrical generation used by the local electric company. The hand generator demonstrated quite well the principle involved providing the electricity that we tend to take for granted. The hand generator is a good tool for teaching this principle.

This generator replaces an old metal generator which fell apart. I purchased a stand-alone light bulb socket from Radio Shack and using the supplied external plug and wires I can easily demonstrate how much work is required to light the bulb.

Kids love generating their own electricity

This was a great introduction to generating electricity, and they came back to them, even when they had batteries available. It was also fun using solar panels to turn the handle as a motor!

NGSS

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.

Elementary Middle School High School

4-PS3-2

Students can make observations of the Hand DC Generator to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.

4-PS3-4

Students can use the Hand DC Generator in an investigation to apply scientific ideas to design, test, and refine a device that converts energy from one form to another.

MS-PS2-3

Students can make observations of the Hand DC Generator and use the data collected in an investigation to ask questions about data to determine the factors that affect the strength of electric and magnetic forces.

MS-PS2-5

Students can make observations of the Hand DC Generator and conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.

MS-PS3-5

Students can use the Hand DC Generator in an investigation to construct, use, and present arguments to support the claim that when the motion energy of any object changes, energy is transferred to or from the object.

HS-PS2-5

Students can plan and conduct an investigation with the Hand DC Generator to provide evidence that an electric current can produce a magnetic field and that a changing magnetic field can produce an electric current.

HS-PS3-1

Students can plan and conduct an investigation with the Hand DC Generator to collect data for use in a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.

HS-PS3-3

Students can plan and conduct an investigation with the Hand DC Generator to design, build, and refine a device that works within given constraints to convert one form of energy into another form of energy.

HS-PS3-5

Students can plan and conduct an investigation with the Hand DC Generator to develop and use a model of two objects interacting through electric or magnetic fields to illustrate forces between objects and the changes in energy of the objects due to the interaction.

This hand-held crank generator produces up to 12 volts of DC electricity. It can be connected to an external circuit with black and red screw terminals on the front of the generator. Housed in transparent plastic, all of the components can be easily observed. Due to the nature of this simple generator, it provides learning opportunities for electric circuits, transfer of energy and magnetic forces.
