To the Editor:
I had the privilege of being one of the judges in the Rappahannock County School Science Fair. The event involved every grade and class in the Elementary and High Schools, and it had to be worked into an already full load of activity by busy teachers and administrators.
Further, the exhibition days coincided with state-wide Literacy Tests. This huge project therefore represented additional voluntary work by hard-working and dedicated school personnel.
The Fair obviously was a great learning experience for the exhibitors, the viewers (students, parents, teachers, and judges), and the demonstrators.
Somehow, the productions by the lower grade children (with the right dose of help from teachers and parents), were both impressive and moving.
Equally impressive were the upper grade exhibits, and the peer teaching represented by the demonstrations on the stage.
Here, teams of Mr. Patterson’s 12th grade physics class demonstrated basic principles of physics to groups of lower grade students.
These included demonstrations of the Bernoulli effect, the torque force, the sound-analyzing oscilloscope, detection of radioactivity, finding the center of mass, and the physics of dry ice.
All these demonstrations made the scientific principles involved easily understandable by, down-toearth, hands-on experiments.
