Unit Plan - Chemical Differences in Emergency Energy Sources

Grades:

7-8

Unit:

Chemical Differences in Emergency Energy Sources

Description:

Students develop atomic and molecular models of energy resources, analyze combustion of various fuels and build circuits with Photovolatic (PV) modules to evaluate and suggest revisions to a disaster preparedness supply list. They then research and...

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):

Students will be able to use a Solar Pathfinder to determine the amount of solar resource lost to shading from nearby trees, buildings, etc. Students will be able to calculate the number of kWh of electricity that can be produced in a specific location and in a specific sized area. Students will be able to calculate the amount of carbon emissions that can be offset due to installing photovoltaic panels of various sizes. Students will be able to calculate the size array needed to offset all electricity use for the high school.
