Ob-Scertainer®: A Better Black Box

Engaging and fun are two expressions often used to describe this kit. The concise lab activities emphasize behavioral reaction and observation. This exceptional Lab-Aid introduces students to the scientific method of problem solving. Students use indirect observations to develop and test hypotheses about the inner configurations of twelve different Ob-Scertainers®. The activities in this kit are suitable for all science curriculums and grade levels.
