Change kinetic energy from your hand into light energy.

Description

Change kinetic energy from your hand into light energy. This hand-held "dynamo" is easily visible. It clearly demonstrates how electrical energy can be produced by moving an electrical conductor through a magnetic field -- a discovery made by Michael Faraday in 1831.

This unit has a built in non-rechargeable, non-replaceable battery that can provide light for many hours showing the efficiency of modern LED lighting technology. However, no batteries are ever required - no bulbs to replace. This is a great safety item. Place one in your car, next to your bed, or in your tool box and you will always have light when you need it without the worry of discovering dead batteries!

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-Held Flashlight 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-Held Flashlight 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-Held Flashlight 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-Held Flashlight 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-Held Flashlight 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-Held Flashlight 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-Held Flashlight 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-Held Flashlight 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-Held Flashlight 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.
