Video shows 30 projects and conducts a dozen on-site student interviews. Some projects are simple: use superglue to stick a coin on the sidewalk and observe passers-by. Some projects are complex: construct a computer-controlled robotic arm. Covers proper experimental methods, including having a large enough sample size, repeating the experiment enough times to get reliable results, and managing variables. Guaranteed to improve the quality of projects at your next science fair! Includes teacher's handbook. 29 min. Grades 7-8, ©1998.
