The National STEM Challenge, presented by EXPLR, is featuring students for their innovative projects focused on bolstering food security, advocating for sustainable agriculture, and advancing agricultural technology. In April, 2024 students recognized through the Challenge will travel to Washington, D.C. to present their work at the National STEM Festival.
The nation-wide challenge invited submissions of Science, Technology, Engineering, and Mathematics (STEM) innovations, inventions, and research from students in grades 6-12. The projects covered six themes, including Future Food.
“As a STEM-Bassador, an EXPLR co-founder, and board member I believe this work to be the most important of my lifetime,” Chef Andrew Zimmern tells Food Tank. “Just look at what these current pioneering change makers are doing! Sustainable food wraps, bio fortifying eggs, remaking how we identify crop disease while we still have a chance to prevent massive losses, soil conservation and repair. These aren’t future changemakers, they are changing our world right now! And we are bringing them to the world, front and center.”
Hao Li, an 11th grader from North Carolina, is one of the students being recognized for her award-winning submission in April. Looking to address food spoilage, Li sought to understand the science of food ripening. Through her research, she uncovered the role that the compound 1-Methylcyclopropene can play in counteracting the effects of ethylene gas, a natural hormone that speeds up ripening. To extend the shelf life of products, she developed a wrap prototype that she hopes can shape future approaches to preservation.
Another STEM Champion, 11th grader Laasya Acharya from Ohio, focused her project on improving crop disease protection methods—an issue that results in the loss of 40 percent of global crops, according to the U.N. Food and Agriculture Organization. Acharya developed Ceres, a device that utilizes advanced imaging and neural networks to identify diseases in fruits, crops, and vegetables. As it develops, she is aiming for at least 85 percent accuracy and a detection time of under 10 seconds per image, while keeping costs below US$40.
And Shelby Scout Hoobler, an 11th grader from Wyoming being recognized for her submission, sought to rejuvenate overgrazed riparian areas. Through detailed soil sample analyses that pinpoint nutrient deficiencies, Hoobler hopes to restore these vital ecosystems and develop a scalable model for environmental recovery efforts globally.
“This is a big topic in Wyoming and the west, so it is exciting for the National STEM Challenge to elevate this type of research,” Hoobler tells Food Tank.
Li, Acharya, and Hoobler, along with 123 of their peers, will gather at the National STEM Festival from April 12-13, 2024, co-presented by EXPLR and the U.S. Department of Education. The event will spotlight their innovative projects to a wider audience but also facilitate interactions with leading figures in government and industry. Organizers hope that this will help to lay the groundwork for future collaborations and breakthroughs.
