Learning Goal(s):
To build empathy for people in emergency situations and an understanding of how access to energy resources can increase one’s safety, health, and comfort. To understand the nature of a variety of energy needs and how different applications have different optimal solutions. To develop models to explain the molecular and extended structures of energy resources, including how the resources change when energy is generated (Electron movement in PV cells, combustion reactions in fuel). To understand that the properties of substances depends upon the atomic / molecular structure, which changes with chemical reactions. To build a circuit that includes a solar module and measure the voltage and current. To gather and evaluate information to describe the impact on society of converting natural resources into PV cells. To design, build and test a device that uses a chemical reaction to generate or absorb thermal energy. Evaluate and revise a plan for the energy resources one should store to prepare for a natural disaster.

Learning Goal(s):
The students will be able to learn what a solar cell looks like and how light energy triggers the cell to release negative charges to move toward the positive side, creating power as it moves from one side to the other. Students will be able to arrange four panels into the correct order to create power for an object and interact with a 3D model of a module to understand how the electricity to power the fan is created. The students will be able to experiment with solar panels (angle, direction) to power a small fan/LED light/circuit board. Students will be able to identify the best position/angle for maximum power. Students will apply scientific ideas to design and test a solar powered water pump that moves water at the fastest rate. Students will experiment and build understanding of parallel and series wiring and how energy moves in these circuits.

Learning Goal(s):
Students will design an investigation to test differences between solar vehicles. They will make claims based on backing evidence, without having directly tested their vehicles before this point. They will use background knowledge regarding pulleys and gears in order to begin the design process. Students will determine which specific design they will be moving forward with for the next lesson.
