Solar-Powered Oven
WHAT WILL YOU MAKE?
Heat up some food with your very own solar-powered oven made from an old pizza box and tin-foil!
WHAT WILL YOU LEARN?
You will learn to use common items to construct an over that trasnforms solr energy into heat.
STEPS
STEP 1
Cut and Line the Box
- Use the ruler and box cutter to cut a three-sided flap into the top of the pizza box lid. Make sure to leave at least an inch of border around the flap.
- Glue aluminum foil to the bottom side of the lid and the insides of the box.
- Try to make the foil as smooth as possible, like a mirror.
STEP 2
Add the Plastic Wrap
- Stretch some plastic wrap across the opening on top of the lid of the box and tape it down.
- Now add another layer of plastic wrap below the opening and tape it to the lid.
- Do not tape any plastic wrap to the flap that is lined with foil. It should only be taped to the edges of the lid across the opening.
STEP 3
Add the Construction Paper
- Line the bottom of the box with black construction paper and glue it down.
WHAT'S HAPPENING HERE?
A solar over works by transforming solar (light) energy into heat. The black bottom of the solar oven acts as heat sink, absorbing sunlight and heating up. It then radiates that heat to warmt he food in the oven. The foil reflects the light fromthe sun onto the black surface and the food to heat them. The plastic window holds the heat in while the cardboard insulates the oven.
Materials:
- Pizza Box
- Aluminum Foil
- Plastic Wrap
- Black Construction Paper
- Glue Stick
- Tape
- Ruler
- Pen/Pencil
- Box Cutter
- Bamboo skewer or wooden dowel or any stick that is at least 1' long

Maker Camp Project Standards
Based on NGSS (Next Generation Science Standards)
NGSS K-2 Engineering Design
The Next Generation Science Standards (NGSS) are K–12 science content standards.- K-2-ETS1-1. Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool.
- K-2-ETS1-2. Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.
- K-2-ETS1-3. Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.
NGSS 3-5.Engineering Design
The Next Generation Science Standards (NGSS) are K–12 science content standards.- 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.
- 3-5-ETS1-2. Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
- 3-5-ETS1-3. Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
NGSS MS.Engineering Design
The Next Generation Science Standards (NGSS) are K–12 science content standards.- MS-ETS1-1. Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
- MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
- MS-ETS1-3. Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
- MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.
NGSS HS.Engineering Design
The Next Generation Science Standards (NGSS) are K–12 science content standards.- HS-ETS1-1. Analyze a major global challenge to specify qualitative and quantitative criteria and constraints for solutions that account for societal needs and wants.
- HS-ETS1-2. Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
- HS-ETS1-3. Evaluate a solution to a complex real-world problem based on prioritized criteria and trade-offs that account for a range of constraints, including cost, safety, reliability, and aesthetics as well as possible social, cultural, and environmental impacts.
- HS-ETS1-4. Use a computer simulation to model the impact of proposed solutions to a complex real-world problem with numerous criteria and constraints on interactions within and between systems relevant to the problem.
