Hundreds of high school juniors and seniors from Utah and Idaho will be exposed to the possibilities that science holds for them Saturday at the University of Utah.

Hosted by the College of Science and the College of Mines and Earth Sciences, Science Day is the largest student-recruitment day at the university. Lunch and the sessions are free.

The day will feature academic advice, demonstrations and a talk by Mary C. Beckerle, biology professor and executive director of the U.'s Huntsman Cancer Institute.

In a "Physics in Action!" demonstration, scheduled in the James Fletcher Building, Room 101, from 2-2:45 p.m., specialists Ziggy Peacock and Adam Beehler will show properties of gravity, velocity, electromagnetism and air. During the demo, a pingpong ball will be shot through three soda cans.

Any Utah and Idaho high school junior or senior — and any high school teacher or counselor — may attend by registering at the Olpin Union Building's main foyer on Saturday.

Those interested can contact the College of Science for more information at (801) 581-6958, or go to the Web at www.science.utah.edu/cosdayedu.html, where an online registration form is available.
