Last week we completed one of our favorite projects of the year...Solar Smores. It is a great introduction to our solar energy unit. The solar cooker is easy to make. Start with a couple of copy paper lids. Line them with foil. Place one graham cracker, chocolate, and marshmallow in the cooker per child (you can fit about nine in a box). Cover the top of the box with cling wrap. Tape well around the edges to seal the cling wrap. Set the cooker in a sunny spot. They only take about 15-20 minutes to make, depending how hot the day is. Be careful, the chocolate gets very hot! Then top with the second graham cracker and enjoy. You can also make individual boxes with old shoe boxes, if you prefer.
It is a great project to teach kids that the sun give us heat. We talk about how the aluminum foil absorbs the sunlight and how the cling wrap traps the heat.
The day after the project I had the students write about the steps to make Solar Smores. Click on the picture to get the freebie.
