Evan Mackall, 10th grade, also won a Grand prize for his Great Sea Monkey Doomsday Experiment in which he tested the toxicity of several substances on brine shrimp. Travis McDaniel, Erik Peyton, and Eric Blacklock, all in 12th grade, won the team prize for their Molecular Madness experiment in which they generated oxygen and hydrogen gases using batteries, graphite rods and salt water. Grand prize-winners and runners-up won a variety of prizes and the opportunity to show off their brain power and meet other students with interests in science and engineering. Students who competed in this fair can now compete in the Sacramento Regional Science and Engineering Fair held the last week of March.
