NASA’s BEST Students: Grades 6-8
Build a Solar Oven
Design an oven to cook while on the moon.
Middle school learners will be guided through a series of challenges that follow the engineering design cycle. Join NASA on an adventure through solving an engineering challenge to create an oven using the energy from the sun.
To demonstrate an understanding of the Engineering Design Process while utilizing each stage to successfully complete a team challenge.
To design and build a solar box cooker, and test it to see if it works well enough to make S’mores!
- General building supplies
- Cardboard box
- Aluminum pans
- Aluminum foil
- Black construction paper
- Plexiglass or plastic wrap big enough to cover the box
- Sunshine, OR gooseneck lamp with 100 W bulb
- S’mores fixin’s (graham crackers, marshmallows and chocolate)
- Oven mitts or tongs
- Ask, Imagine and Plan
- Experiment and Record
- Quality Assurance Form
- Fun with Engineering at Home
It is recommended to take a few minutes at the start of the session to discuss safe handling procedures of the food and of their solar ovens when exposed to the sun: (1) Remind students the importance of hand washing before handling food; and (2) Ovens will get hot and will require the use of protective gear or a tool to manipulate items in and out of the ovens.
Please note: This activity may require two 60-90 minute sessions to complete.
- Have students watch the video “Living on the Moon“: http://svs.gsfc.nasa.gov/goto?10515
SET THE STAGE
ASK, IMAGINE, & PLAN
- Share the Design Challenge with the students
- Remind students to imagine a solution and draw their ideas. All drawings should be approved before building.
- Tell students that if they succeed in their design, a tasty treat will be had!
- Hand out the materials to the students and challenge them to build their own solar ovens.
- Have students follow the directions on the Experiment and Record worksheet to complete their experiment.
- Once the oven is built, students should place a S’more and the thermometer in the box and cover with plastic wrap or plexiglass lid.
- Place the box in direct sunlight (students may have to tilt the box so that there are no shadows inside). If it is a cloudy day, use a goose neck lamp with the 100 W bulb.
- Ensure students use oven mitts when moving the plexiglass lid or removing items from the solar oven once exposed to the sun.
- If there is time, have students inspect their designs and the experiment results. Allow teams to rework their designs if needed.
Engage the students with the following questions:
- Whose oven reached the highest temperature? What was that temperature? Did it melt the marshmallows and the chocolate?
- What could you have done to make your solar oven work better?
- Does it make a difference using actual sunlight compared to light from a lamp? Why or why not?
- How did the distances from the bottom reflective surface affect the cooking of the food in your oven?
END OF PROGRAM
This session concludes the NASA’s Beginning, Engineering, Science and Technology series. Students now should have a firm grasp of the Engineering Design Process and how it is applied in real applications of our quest to travel to the Moon, Mars and beyond. Print out a certificate for each student for completing all the steps to becoming a NASA’s BEST student (see end of guide).
Project 1 Build a Satellite to Orbit the Moon
Use the engineering design process to build a satellite that can orbit the moon.
Project 2 Launch Your Satellite
Use the engineering design process to construct and test a launch system to deliver a satellite into moon's orbit.
Project 5 Design a Landing Pod
Use the engineering design process to successfully land a lunar buggy on the moon's surface.
Project 6 Design a Crew Exploration Vehicle
"Houston . . . There is no problem." Use engineering design to create a crew exploration vehicle to return humans to the moon.
Project 8 Design a Lunar Thermos
