Ob-Scertainer® - A Better Black Box


Help teach students to "think scientifically". Lab Kit for 24 students.

Students experiment to develop a hypothesis about the inner configuration of one of 12 different ob-scertainers, using indirect observation. They test their hypothesis, and make a new one if necessary. If desired, the students continue to experiment and can actually verify their hypothesis. Useful in a variety of settings, this tool introduces students to the scientific method of problem solving. Rather than emphasize "what it is," the lab activities focus on behavioral reaction and observation.
