Hand-Cranked Generator

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.

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.

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.

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.

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.

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.

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.

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.

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.
