Unit Plan - Chemical Differences in Emergency Energy Sources

Grades:
7-8
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.

Solar Updraft

Let's Build Our Wind and Solar Energy Toy

Grades:
3-8
Learning Goal(s):
Students will determine that thermal energy resulting from the sun’s radiation can create an updraft that will power a turbine to spin.                                                Students will identify characteristics of turbine design that improve the success of their device.Students will utilize content from previous phenomena they investigated, such as the chimney stack effect and Norwegian candle toys, to determine how to best harness the energy transformed by their device from the sun.
