SummaryStudents explore the methods engineers have devised for harnessing sunlight to generate power. First, they investigate heat transfer and heat storage through the construction, testing and use of a solar oven. With a lesson focused on photovoltaic cells, students learn the concepts of energy conversion, conservation of energy, current and voltage. By constructing model solar powered cars, students see these conceptual ideas manifested in modern technology. Furthermore, the solar car project provides opportunities to explore a number of other topics, such as gear ratios and simple mechanics. Both of these design and construction projects are examples of engineering design.
Designing and building solar cars and solar ovens are examples of engineering projects that demonstrate to students how engineers apply their brains and imaginations to make an impact on the world through innovative designs.

Students learn how the sun can be used for energy. They learn about passive solar heating, lighting and cooking, and active solar engineering technologies (such as photovoltaic arrays and concentrating mirrors) that generate electricity.
Students discuss where energy comes from, including sources such as fossil fuels, nuclear and renewable technologies such as solar energy. After this initial exploration, students investigate the three main types of heat transfer: convection, conduction and radiation. Students learn how properties d...
Students learn about the definition of heat as a form of energy and how it exists in everyday life. They learn about the three types of heat transfer—conduction, convection and radiation—as well as the connection between heat and insulation.
Students learn and discuss the advantages and disadvantages of renewable and non-renewable energy sources. They also learn about our nation's electric power grid and what it means for a residential home to be "off the grid."
Each TeachEngineering lesson or activity is correlated to one or more K-12 science,
technology, engineering or math (STEM) educational standards.
All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN),
a project of D2L (www.achievementstandards.org).
In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics;
within type by subtype, then by grade, etc.

Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.
(Grades 6 - 8)
Do you agree with this alignment? Thanks for your feedback!This standard focuses on the following Three Dimensional Learning aspects of NGSS:
Science & Engineering Practices Disciplinary Core Ideas Crosscutting Concepts Construct, use, and present oral and written arguments supported by empirical evidence and scientific reasoning to support or refute an explanation or a model for a phenomenon.Science knowledge is based upon logical and conceptual connections between evidence and explanations. When the motion energy of an object changes, there is inevitably some other change in energy at the same time. Energy may take different forms (e.g. energy in fields, thermal energy, energy of motion).
Lesson 1, Using Heat from the Sun and associated activity Cooking with the Sun - Creating a Solar Oven: The three primary modes of energy transfer—conduction, convection and radiation—are discussed in the context of engineers exploiting heat from the sun. Then students create and use solar ovens.
Lesson 2, From Sunlight to Electric Current and associated activity Racing with the Sun - Creating a Solar Car: Students learn how the sun's energy can be used to produce electricity. Then they create and race model solar cars.
