Social studies classes could use this resource to discuss solutions for communities experiencing power outages or in areas without electricity.
A discussion about renewable energy and the use of solar in different parts of the world would be a logical follow-up to this activity.
Have students carry out modifications to the provided design and challenge them to optimize their cookers.
Similar resources to consider include this video about reusing materials to make a solar oven and these resources about "daylighting" homes and buildings and passive home design.
Scientist Notes
This resource is a lesson plan describing how do build a solar oven as well as how a solar oven works. The lesson plan comes from the Department of Energy, and is clearly presented and simple. This resource is recommended for teaching.
Standards
Science and Engineering
ETS1: Engineering Design
3-5-ETS1-1 Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
MS-ETS1-2 Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
PS1: Matter and Its Interactions
5-PS1-3 Make observations and measurements to identify materials based on their properties.
MS-PS1-6 Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.
PS3: Energy
MS-PS3-3 Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.
HS-PS3-3 Design, build, and refine a device that works within given constraints to convert one form of energy into another form of energy.
