Energy Transfer Through Kinetic Changes

Mrs. Howard introduces an investigation into energy transfer using a wind turbine system. The lesson involves writing a claim evidence reasoning (CER) report. Students explore how kinetic energy changes result in energy transfer, focusing on wind turbines converting wind energy into electricity. They identify energy types in the system, use a simulation to collect data on wind speed and electrical power, and compile a CER report based on their findings.

What is the main claim that needs to be proven in the investigation?

• When the kinetic energy of an object changes, energy is transferred to or from that object.

• Energy cannot be transferred between objects.

• Wind turbines can only generate mechanical energy.

• Kinetic energy is always conserved.
