Itโ€™s that time of year where everything is upโ€ฆ the sun, the temp, your kidโ€™s activity levelsโ€ฆ Whatโ€™s a teacher to do? Make Sโ€™mores, thatโ€™s what! I love pulling out this fun sโ€™mores science experiment at this point in the year. Itโ€™s a great experiment to help students learn more about the sunโ€™s energy, or about heat transfer!

Pulling in the Science Standards

Making sโ€™mores in a solar oven is an easy and fun experiment you can do in one day! (weather permitting!) I love the flexibility of this fun experiment. You can use it to learn more about the steps in the scientific experiment, or to learn more about the sunโ€™s energy.

When I completed this activity in second grade, we used it to demonstrate how the sunโ€™s energy could heat the Earth. In third grade, we used it to discover how heat can transfer. Both used this exact experiment, but for todayโ€™s post Iโ€™m going to focus on the sunโ€™s energy.

Pulling Your Materials

For this sโ€™mores experiment, you going to need to following materials:

  • marshmallows
  • graham crackers
  • chocolate bars
  • quart size baggies
  • foil
  • pizza box or other type of box

In addition, I like to print out lab recording sheets for each student to glue into their Science journals as well as an extra copy for me to model.

Setting the Sโ€™More Stage

To set the stage for this experiment, we first discussed the sunโ€™s energy or heat and how it can warm the Earth. Living in Florida, it was easy to relate the sun to warming our faces or heating up our playground equipment. But, could the sunโ€™s energy or heat be used to cook? With that question in mind, we set out to answer our question! I like to do this beginning part of the experiment in the morning so that the Sโ€™mores have all day to sit out in the sun.

Together we filled out the question and hypothesis part of our lab write up sheet. Then, we gathered supplies and wrote those down.

Key ideas to guide your discussion:

  • Will the sun warm the Sโ€™mores?
  • How will we know?
  • How might the Sโ€™mores change during the experiment?
  • What hypothesis can we make using our knowledge of the sunโ€™s energy?

Sโ€™Mores Science Experiment

From there, we worked to start setting up our experiment. First, I had the students walk me through adding the foil to the pizza box. As a taped it in, we discussed how the foil was going to act as a mirror to seal in the heat from the sun and โ€œbounceโ€ it around in the box.

As we discussed and I completed the โ€œovenโ€, we wrote down what I was doing on our lab recording sheet.

Finally, it was time to assemble our Sโ€™mores. To keep it simple (and the lesson moving!) I demonstrated how to set up the Sโ€™more and wrote the steps on our recording sheet. Once students finished copying down the steps, I gave out materials for them to make their own Sโ€™Mores. I also passed out a quart sized baggies to each student and one permanent marker to each table. After students assembled their Sโ€™more, they wrote their name on the baggie and slide the Sโ€™more in.

We also made a little sign to remind our school friends not to touch our science experiment as it sat out in the sun.

The Sunโ€™s Energy Heating the Earth

We brought the pizza box and Sโ€™mores outside for the remainder of the day. As a class, we decided to keep the lid open so that the sunโ€™s rays could heat up the space in the box (but that could be a whole other version of this science experiment!)

After an hour or so, we went back to check on the Sโ€™mores and made observation notes in our science journals.

At the end of the day, we were ready to bring the Sโ€™mores inside and write down what happened!

Recording Our Findings

To keep things from getting too messy, I opened one Sโ€™more and walked around the room. Then, we wrote our observations and results. The kids couldnโ€™t believe how melted the chocolate and marshmallow had become!

We also brought the experiment back to our original question, can the sunโ€™s energy heat the earth? How did we know it did? These are all things I made sure the kiddos included in their conclusions area of their lab write up.

Enjoying the Sโ€™Mores

After all that, it was FINALLY time to enjoy our ooey-gooey Sโ€™mores! For this part, I passed out their sโ€™mores baggies and had them eat the treats very carefully over paper towels. Once the finished, they had to wash their hands and clean up their desks! No ants for this teacher please!

This was such a fun and easy experiment to do! Perfect as part of a weather unit or as an end of the year fun treat! Either way, I know your students will enjoy!
