Under Ms. de Geus’ guidance, the kindergarteners were placed into groups and began constructing their solar ovens step by step. To start, students assembled small cardboard pizza boxes and lined the inside with aluminum foil. Next, they cut a small flap in the top of the box and covered the opening with plastic wrap to be able to let sunlight in without letting heat escape - just like a window! The students then learned about reflection and taped additional foil onto the flap so that sunlight could reflect into their box. Using pencils to prop up their box flaps, the kindergarteners discussed what color plate should be placed into their solar oven and why a black plate would capture heat and warm the s’mores the fastest. 

Following the lesson, Ms. de Geus shared that one of the most meaningful aspects of this activity is the challenge it provides the kids. “I love any project that gives students the opportunity for a healthy amount of struggle. The kindergarten scientists will have to test and change their designs to make them work. It is a great way to practice perseverance and hone their innovation skills in a fun and tasty way,” Ms. de Geus said. 

In addition, Ms. de Geus shared that watching her students celebrate perseverance and embrace experiences is one of her favorite parts of teaching Lower School science. “I love the excitement and enthusiasm that the younger students bring to science. Everything is exciting, and they are always ready to make mistakes and get messy. It is also really rewarding to see their problem-solving skills grow throughout the year, and their ability to push through challenges and embrace failing is always great to see!” Ms. de Geus said.

Following the construction of their solar ovens, the kindergarten students took their projects outside and got to show their innovation skills to their parents, who were invited to campus for a s’mores party! Incredible work, young scientists!
