A Science Day competitor watches as the device he has designed to protect a water balloon in a fall plummets toward the ground.

More than 450 high school students participated in PSU’s Science Day 2010 on April 22. Students competed individually and in teams in four areas: Chemistry Capers, Physics Frolics, Earth and Space Science, and the Biology Bowl.

Some of the competitions included the popular mouse trap car, in which students design and build cars powered only by a mousetrap; the water balloon drop, in which students attempt to design and build a container to protect a water-filled balloon in a 3-story fall; and seismic shakers, in which students construct a tower of craft sticks and glue that can withstand an earthquake.
