The Solar Power Challenge

Strand/Standard 4.2.4 Design a device that converts energy from one form to another. Define the problem, identify criteria and constraints, develop possible solutions using models, analyze data from testing solutions, and propose modifications for optimizing a solution. Emphasize identifying the initial and final forms of energy. Examples could include solar ovens that convert light energy to heat energy or a simple alarm system that converts motion energy into sound energy. (PS3.B, PS3.D, ETS1.A, ETS1.B, ETS1.C)

 

Lesson Performance Expectations

Students will identify photovoltaic solar power as a source of energy and explain what happens when a photovoltaic cell is shaded.

Who Turned Out the Lights

Strand/Standard 4.2.3 Plan and carry out an investigation to gather evidence from observations that energy can be transferred from place to place by sound, light, heat, and electrical currents. Examples could include sound causing objects to vibrate and electric currents being used to produce motion or light. (PS3.A, PS3.B)

 

Lesson Performance Expectations

Witness a simple phenomenon where the classroom lights are out and all electronic devices/equipment are off as well. They will ask questions about how this would affect their lives and how it is affecting them right now. Students will build a simple circuit with a battery and light.

The Power of Wind

Strand/Standard 4.2.4 Design a device that converts energy from one form to another. Define the problem, identify criteria and constraints, develop possible solutions using models, analyze data from testing solutions, and propose modifications for optimizing a solution. Emphasize identifying the initial and final forms of energy. Examples could include solar ovens that convert light energy to heat energy or a simple alarm system that converts motion energy into sound energy. (PS3.B, PS3.D, ETS1.A, ETS1.B, ETS1.C)

 

Lesson Performance Expectations

Students will identify wind power as a source of energy and use the engineering process to determine construction of the blades, the housing unit and wind power enough volts to light one LED light bulb.
