Students will conduct simple experiments to learn what kind of materials absorb heat from the sun, what kind of materials reflect light from the sun and what color of materials do not get hot in the sun. This lesson gives students experience in beginning to learn about why certain materials and colors are used in solar ovens.

Students will understand that when the sun is lower in the sky, it casts a longer shadow on an object. When the sun is higher in the sky, it casts a smaller shadow. Students will also understand the importance of adjusting the position of a solar oven every half hour or so throughout the cooking process to insure that the bottom of the oven is facing the sun directly in order to maximize heat absorption.

Students will discuss social, cultural, and economic implications of sustainable solar energy.Students will construct and test solar panel arrays to power LED lights, fan motors, and music playersStudents will review circuitry basics and solar cell layersStudents will analyze and share out power generation results with classmatesStudents will construct and test an oxidized copper sheet solar cellStudents will share and analyze oxidized copper sheet solar cell dataStudents will construct and test titanium dioxide coated “raspberry juice” solar cellsStudents will collect and analyze titanium dioxide coated “raspberry juice” solar cell data.Students will discuss results and draw conclusions about variables that may affect power generationStudents will visit a solar cell or silicon manufacturing facility and/or engage with guest speakers. Students will learn more detailed solar cell principles and manufacturing techniques involved in solar cell constructionStudents will research chemicals, materials and procedures for their own solar cell designsStudents will build and present models of their proposed solar cellsStudents will construct and test unique solar cellsStudents will present construction progress and project obstaclesStudents will format solar cell data, draw conclusions, and construct an engineering report as a research poster

Students will be introduced to the vocabulary of observation, hypothesis, and evidence. Students will use the process of science discourse where people respectfully listen and disagree with each other’s ideas.
