Program Highlights

In science the students are studying the scientific method. Our upper elementary students asked a question “Can the sun really bake something?” Here is how they decided to find out.

QUESTION: In our science class, we learned about people using the sun’s power to bake things in solar ovens. Could we get this to work?

MATERIALS: Cardboard boxes, aluminum foil, cinnamon rolls, clear plastic film, tape, and lots of sunshine!

PROCEDURE: Cut a window in the box, then line the box with foil. Put plastic film over the window to keep out bugs and dirt, but still let in the sunshine.

Making a solar oven.

Put a raw cinnamon roll in the box. Set the box out somewhere where it will get sun all day!

Setting up solar ovens

HYPOTHESIS: Actually, we had several….One student thought it would work, one thought it would not, one thought that squirrels would break into the boxes and eat the project!

OBSERVATIONS: March 1, 2018

8:45 AM The dough was pretty gooey when we started. The day was clear and sunny. Hopes were high as we set out the ovens.

11:45 AM The wind has picked up and has blown over our ovens. We repositioned them and taped them in place.

2:45 PM The cinnamon rolls are drier on the edges, but still gooey in the middle. The sun had not cooked them adequately!

3 PM We finished cooking the cinnamon rolls in a toaster oven. Fifteen minutes in there did what the sun could not accomplish in five hours!

The biscuits are in the ovens.


1. Solar ovens in Colorado need to be weighted to withstand Colorado breezes!

2. The winter sun is not strong enough to bake biscuits in a solar oven in Colorado.


Let’s try it again in late Spring!
