Are you looking for a solar project? Here’s a fabulous STEM activity about using the sun to warm items! Your students will love this project, and you will love the detailed teacher's guide full of information and tips.

What is the challenge?

• Students will use materials to design a box oven that will absorb and/or reflect sunlight and create enough heat inside the box to toast a food product.
• We decided s’mores would be a fun item to try!
• Students will test their ovens by trying different materials to determine which absorbs heat the best, and then they will build the version they think will create the warmest oven.
• The final oven will be used to heat and toast a s’mores dessert.
