This spring, students from Postville High School, led by science teacher Sean Singewald, and staff member Annette Frey successfully took part in the Plant the Moon Challenge, a prestigious collaborative initiative involving Northeast Iowa STEM and the Institute of Competition Sciences. Students were tasked with a critical question for the future of space travel: Can terrestrial plant life survive and thrive in lunar regolith?
The Experiment
Using soil engineered to closely mimic the harsh material found on the moon's surface, the PHS team selected a specific crop and designed their own experimental parameters to optimize growth. Some of the materials used to improve the ‘moon soil’ were Iowa topsoil, water from class fish tanks, hydrogel beads, and solid waste from the Decorah fish hatchery. Over an intensive 8-week period, the students monitored variables and gathered data, eventually submitting a comprehensive final report to a global network of professional and student researchers.
The Result
The Postville team’s dedication to scientific rigor paid off on a global scale. Competing against more than 155 high school entries from across the nation and the international community, Postville High School was honored with the award for "Best Overall Growth Rate." Their findings now contribute to the collective effort of expanding humanity's space exploration capabilities and the dream of sustainable life beyond Earth.
