https://www.oercommons.org/courses/energy-efficient-housing-2
We all know that it takes energy to provide us with the basics of shelter: heating, cooling, lighting, electricity, sanitation and cooking. To create energy-efficient housing that is practical for people to use every day requires combining many smaller systems that each perform a function well, and making smart decisions about the sources of power we use. Through five lessons on the topics of heat transfer, circuits, daylighting, electricity from renewable energy sources, and passive solar design, students learn about the science, math and engineering that go into designing energy-efficient components of smart housing that is environmentally friendly. Through numerous design/build/analyze activities, students create a solar water heater, swamp cooler, thermostat, model houses for testing, model greenhouse, and wind and water turbine prototypes. It is best if students are concurrently taking Algebra 1 in order to complete some of the worksheets.Integrated Teaching and Learning Program,See individual lessons and activities.Education2015-10-16T16:47:44.986600Course Related MaterialsPhotovoltaic Efficiency
https://www.oercommons.org/courses/photovoltaic-efficiency-2
Through a series of four lessons, students are introduced to many factors that affect the power output of photovoltaic (PV) solar panels. Factors such as the angle of the sun, panel temperature, specific circuit characteristics, and reflected radiation determine the efficiency of solar panels. These four lessons are paired with hands-on activities in which students design, build and test small photovoltaic systems. Students collect their own data, and examine different variables to determine their effects on the efficiency of PV panels to generate electrical power.Integrated Teaching and Learning Program,William Surles, Abby Watrous, Jack Baum, Stephen Johnson, Eszter Horyani, Dr. Gregor Henze, Malinda Schaefer Zarske, Denise W.

https://www.oercommons.org/courses/solar-water-heater-3
Student teams design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy. This thermal energy is next transferred to water (to be used as domestic hot water) in the form of heat. In doing this, students gain a better understanding of the three different types of heat transfer, each of which plays a role in the solar water heater design. Once the model devices are constructed, students perform efficiency calculations and compare designs.Denise W. CarlsonIntegrated Teaching and Learning Program,Landon B.

People use energy in all aspects of their lives â for cooking, lighting and entertainment. Much of this energy use takes place in buildings, such as our homes. To save money and reduce the impact on our environment, many people are reducing their energy use. One way is to hire engineers to perform home energy audits to understand the ways we use energy and identify ways we can conserve energy. In this activity, students act as energy conservation engineers and identify the ways energy is conserved or wasted. They also learn many ways to personally conserve energy everyday.Denise CarlsonIntegrated Teaching and Learning Program,Malinda Schaefer ZarskeNatalie MachSharon D.
