but with an environmental twist. We came up with a project that was different from last year, but was still important research to conduct. We decided to take samples of the water in our homes, schools, and communities to find out if our water quality was up to EPA standards. We sterilized seven mason jars using a pressure canner and distilled water. We took samples of our different water sources and tested them with 18-in-1 test strips. We hypothesized that because bottled water has to be approved by the FDA and the FFDCA, the drinking standards should be higher, and the water will be cleaner than the school and tap water. We found that the Jackson Grammar School water fountains were actually the cleanest, proving our hypothesis wrong. The contamination levels were relatively similar across all of our samples, they tested below EPA-recommended limits in all areas, except for nitrite, sulfate, and fluoride levels. We were pleased to have no real concerns in our water.
KATIE LARACY “Clean Energy, How Easy can it be?” When coming up with my project for the 2025 Stem Expo, my mind went straight to fossil fuels, and why people will constantly choose them over clean energy for convenience. I thought about how kinetic energy can be found all over the earth, but my mind instantly went to the energy found in water. Approximately 71% of the earth is covered with moving water like oceans and rivers. Using the movement found in this water to create an electric current with a magnetic field would provide clean energy that does not strip away any of the Earth’s natural resources or pollute the atmosphere. For my project, I built multiple prototypes that use the process of electromagnetic induction to show energy being created using an an alog galvanometer. Sure enough, energy was created, which led me to think, ‘How can I make this process simpler?’With my prototype, using wire for energy transportation, my mind fell to making this process wireless. My next step in this experiment is to wirelessly transport the energy from my prototype. I am not yet sure how to execute this next step; it’s possible that a laser could be used to effortlessly transport the energy from point A to point B with no wires required. Science is complicated, but I want to make clean energy as simple as it can be. It was so cool to be able to see all the different projects at this year’s STEM Expo, and to be able to share my project with people in the community. I love how the Expo is able to bring so many people with a love for science together in one building, whether they are the students or the judges. It was very interesting hearing about other people’s projects, and what led them to come up with those topics. All in all, I think that the STEM Expo was a very fun day, and I can’t wait to be back next year!
Students and families then gathered to hear from the STEM Expo’s keynote speaker, Kennett High School alum Colin Foord, who is the co-founder of the marine biolog ical art duo Coral Morphologic, located in Miami, Florida. Students heard about Colin’s work in developing the world’s first multimedia coral aquaculture studio and were treated to a look at his live-streaming Coral City Camera.
The awards ceremony was the highlight of the day, honoring the following winners: In the Elementary School category, first place went to Nelly Lamneck, 4th grade at Mountainside Intermediate School for her project, “Does a Broken Reed Change the Pitch?” Second place was awarded to Hazel Dufilho, 5th grade at Jackson Grammar School for her project, “Sourest Candy,” and Vivian Klein, 5th grade at Jackson Grammar School earned third place with her project, “Rise of the Cookies.”
In the Middle School category, Addy Jaus, 7th grade at Josiah Bartlett Elementary School, took the top prize for her project, “Trashing Soil Pollution.” In second place were Skyler Boris and Emmett O’Brian, 7th graders at Josiah Bartlett Elementary School, with their project, “Comparing Different Bounce Heights on Different Surfaces,” while Levi Roberts and Brighton Oliver, 6th graders at Josiah Bartlett Elementary School, secured third place with their project, “Powerful Paper.”
In the High School category, Ayten Soylemez, 11th grade at Fryeburg Academy, won first place for her project, “Language of Movement.” Second place was claimed by Tomona Arai, 10th grade at Fryeburg Academy, with her project, “Effect of Transporter Mutation and Potassium on Radiocesium Distribution in Arabidopsis Thaliana from the Fukushima Nuclear Explosion Accident,” and third place went to Nia Lajoie, 10th grade at Kennett High School, for her project, “The Effects of Nicotine Products on the Gut Microbiome.”
Mount Washington Observatory Emerging Scientist awards went to Max Morrow, 6th grade at Jackson Gram mar School, for his project, “Bolts and Wire,” and to Emily Fields, 9th-grade at Kennett High School, for her project, “Hot Topic: The Greenhouse Effect.”
