Young scientists strut their stuff at STEM Expo

William Jessup event showcases student projects
-A +A

The third annual Placer County STEM Expo returned to William Jessup University Saturday, drawing students from across the county to display their projects.

The Science, Technology, Engineering and Mathematics Expo offered seven unique categories: Rube Goldberg (illustrated or built contraptions); Invention; Science Fiction; Environmental Innovation (facilitates environmental thinking); Reverse Engineering (figuring out how things work); Robotics Engineering; and Scientific Inquiry.

Catherine Colella, of Roseville, 13, a seventh-grader at Western Sierra Collegiate Academy, won an overall first place for scientific inquiry with her “Got Thermal Conductivity?” project, which measures the thermal conductivity of wires made of varying materials and of varying gauges, earned her a spot at the California State Science Fair held in Los Angeles in April.

Rocklin’s Tech Tofu robotics team split into two teams to compete in the Robotic and Invention categories. The Robotics team of Shaurya Grover, Ronak Brar and Charley Holmes took first place, while the Invention team of Nathaniel Daniel, Haagen Woodford and Davin Nugyen took second. Tech Tofu sibling Gabrielle Daniel won third place in the Science Fiction category.
