My interest in science started at South Eugene High School in 1960, but it was biology, not space travel, that first hooked me. I loved watching tiny creatures through a microscope, dissecting frogs and anatomy.
Before the annual science fair, I searched for project ideas. My teacher knew of a student who had kept a chicken heart beating in a saline-filled petri dish. Because my dad hauled these critters to the Swift & Company slaughter house, he had access to live chickens. I got the saline solution at a drug store. The teacher anesthetized the chicken, and we dissected its chest and removed its heart. That heart kept beating for over an hour, which fascinated the visitors and the science fair judges, who awarded me first place. Continue reading →
By Steve Frandzel By analyzing average daily water flow rates through the Corvallis sewer system and the length of time that pumping stations operated, Mathew Palmer and his Expo project team determined that large volumes of excess water is infiltrating the system through cracks and fissures in underground pipes.
“Whenever it rains a lot, water seeps into the sewer system through these cracks,” explained Palmer, who is graduating with a degree in chemical engineering. “That means the pumping stations have to work longer, and that costs Corvallis money that could be spent on other things.” Continue reading →
Corbin Moser’s Expo team was tasked by EarthCruiser USA in Bend, Oregon, to increase the efficiency of solar panels mounted on the company’s all-terrain expedition vehicles.
EarthCruiser vehicles are designed to be self-sufficient during long-term travel in remote locations. They rely on solar panels coupled with batteries for power when parked, and are equipped with an onboard water purification system. Continue reading →
By Steve Frandzel After major rainstorms, Pine Creek outside of Halfway, Oregon, floods surrounding farmland and threatens nearby homesteads and sewage holding lagoons.
Will Dickman and his fellow Expo team members considered several possible solutions to mitigate the flooding and presented their recommendations to the Oregon Department of Transportation. Continue reading →
By Steve Frandzel Seeking a way to improve the navigational ability of robots, Colin Comard and his Expo team turned to the animal world — specifically the bat’s remarkable ability to maneuver quickly and precisely using sonar.
“Bats have specialized anatomy and biology that allow them to navigate with echolocation,” said Comard, who is getting a degree in electrical and computer engineering. “We’re trying to use that evolutionary advantage for our own robots to help them navigate better.” Continue reading →
