I found this resource on the web along with a link to Bill Ferriter's blog. He is a science teacher and a strong supporter of students analyzing, synthesizing, comparing and contrasting and evaluating in every single class every single day. The standards ask students to grapple with the concept of energy, and the notion it is neither created or destroyed. The goal of the below lesson was to help students recognize that light energy can be converted into heat energy. This teacher conducted this investigation with students right before Thanksgiving and made s'mores in the ovens. This could be ramped up with engineering concepts as students evaluate their design, and remodel for more efficiency or used as an access point to the concept of energy transfer and allow the kids an opportunity to plan, and build something.
Let us know in the comments on the blog if you try it on with students, and how it goes. Also, if you have an idea to modify the lesson to be used in your specific program let us know! Share with your peers your successes, or challenges that arose within the project. Please share any pictures of completed solar ovens so we can add to the blog and share our students successes.
The
below handout can be downloaded for free from the linked blog in the first
paragraph or from this google doc link.

Determining the Best Approach to
Building a Solar-Powered Pizza Box Oven
Over the next few days
in class, we’ll be building a solar-powered pizza box oven and cooking our own
S’mores. Your group will be responsible
for determining the best setup for your solar powered oven based on what you
already know about energy. Make good
decisions and you’ll have delicious S’mores to eat. Make poor decisions and you’ll be left eating
cold marshmallows on hard graham cracker!
Start by watching this
video outlining the steps necessary for building your solar-powered oven: http://bit.ly/solarovensmore
Then work through the
steps below to determine the best strategy for building your oven. Remember to NOTE: Note
key points, Observe options, Think it through and identify
possibilities and Express
your personal choice.
-------------------------------------------------------------------------------------------
Step 1:
Note all of the variables that you can control in the design of
your oven.
What options do you have in designing your pizza box oven? What can you intentionally change about your
oven design?

Step 2:
Think together and identify three variables that will be the most
important to designing a successful oven.
Can you defend your choices using science knowledge gained during our
energy unit?

Why this Variable Matters:

EXPRESS
YOUR PERSONAL CHOICE BY BUILDING AND TESTING YOUR SOLAR POWERED OVEN. COMPARE YOUR RESULTS TO THE RESULTS OF GROUPS
THAT USED A DIFFERENT OVEN DESIGN FROM YOUR OWN.
Step 3: Planning for future ovens
What changes would you make if we built another oven? How would those changes improve your results?
