Students from two Missouri schools are in the running for national science competition awards. The ExploraVision Awards will be handed out in June to student inventors. 24 teams of students are in the running. Among them is one from Ladue Horton Watkins High School in St. Louis. Two 18-year-old girls have developed a system that would decompose all trash into fertilizer. She says several ideas were considered before settling on this proposal. The second Missouri team is also from the St. Louis area. 8th Graders from John Burroughs School have come up with a device to improve the lives of sufferers of Amiotrophic Lateral Sclerosis – also known as Lou Gehrig’s Disease.
