Did you know in August there are two separate special days dedicated to marshmallows? One day is August 10, which is National S’mores Day, and you can’t have a s’more without a marshmallow! The other day is August 30, which is Toasted Marshmallow Day! So of course, this month’s challenge has to do with marshmallows, especially toasting them AND making s’mores! Your challenge is to create a contraption that will make a marshmallow warm and soft along with chocolate to make a s’mores. You probably will not be able to really toast it since fire will not be used. You’ll be using the sun’s heat energy to help you accomplish the task. What materials will work best to capture the heat? How large should the contraption be? What shape, size, and design should it be to be most effective? How can you measure the effectiveness of the contraption?
Your contraption and creation do have some criteria and constraints. Each contraption or solar oven should test one marshmallow or piece of chocolate at a time. All the marshmallows and chocolate should be about the same size and type. While testing, the solar ovens should be placed in the same sunny area. Use the same thermometer for taking the temperature inside the box.
