This project aims to deepen your understanding of thermal energy transfer by designing and building a solar oven. You'll apply scientific principles such as conduction, convection, and radiation to create a device that maximizes solar energy for cooking. Through hands-on experimentation and investigation, you'll develop skills in planning and carrying out scientific inquiries, while also enhancing your ability to communicate findings through a video presentation.
Learning goals
In this project, you will learn how to apply scientific principles to design and test a device that controls thermal energy transfer. You will explore the concepts of conduction, convection, and radiation, and understand how they affect heat transfer. You will develop skills in planning and carrying out investigations, providing evidence to support your explanations and design solutions. Through hands-on experimentation, you will gain insights into the efficiency of solar ovens and the factors that influence thermal energy maximization.
Standards
NGSS - MS-PS3-3: Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.
NGSS - MS-PS1-6: Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.
Common Core - CCSS.ELA-LITERACY.RL.6.3: Describe how a particular story’s or drama’s plot unfolds in a series of episodes as well as how the characters respond or change as the plot moves toward a resolution.
Products
Design and build a solar oven using everyday materials to demonstrate how thermal energy can be maximized through solar radiation. Conduct experiments to test its efficiency in cooking different foods. Create a video presentation explaining your design process, the scientific principles applied, and the results of your testing phase.
Launch
Begin your project by watching a short video that demonstrates various solar ovens in action. Discuss with your peers how each design maximizes thermal energy transfer. Then, brainstorm everyday materials you could use to build your own solar oven. Finally, conduct a simple experiment to observe the effects of sunlight on temperature using thermometers and different colored papers, noting which colors absorb more heat.
Exhibition
Organize a science fair where you showcase your solar oven designs and present your video presentations to classmates, teachers, and family members. Facilitate a gallery walk where you can view and provide feedback on each other's projects, focusing on the design process and scientific principles applied. Engage visitors by demonstrating the cooking capabilities of your solar ovens, allowing them to taste-test the food prepared. Create informative posters or digital slideshows to accompany your displays, highlighting key findings and the efficiency of your designs. Include a Q&A session where you can answer questions and discuss the challenges and successes encountered during the project.
