The sky was clear this morning, the news said our weather would be partly cloudy with highs between 51-58. We decided it was a good day to build our solar oven and try it out. We used hot glue instead of wood glue, making the process quicker with less waiting time. You never know when Washington weather could take a turn for the worse.
When it was completed we took it outside and found our focal point to get the highest temperature we could. We measured the temperature at 95 degrees celsius which converts to 203 degrees fahrenheit. We decided to try and make toast in our oven. Once set-up we had to wear glasses and avoid looking directly at our toast or the oven. It appeared that our toast was glowing!
We could tell the solar oven cooked differently than a toaster or convection oven. The toast barely turned color but became crispy and we observed it smoking as it cooked. The total cook time was 13 minutes, with approx. 6-7 minutes for each side.
Some of us enjoyed our toast with jelly while others just couldn't wait =)

Hi Ayler and Girls, What a neat thing to build.I have not seen a toaster that looked like that before.What else can you cook in it? Keep up the fun work and let me know of your other science projects that you do.Ok bye for now and say that must be a smart teacher you have teaching you these things.
Wow! What a cool experiment...good job, guys! I'm really excited about your science class this year, and can't wait to hear more! -Alicia, Ethan and Kieran
