Ob-Scertainer® Scientific Method
This kit allows students to think scientifically.
Its emphasis is on behavioral reaction, rather than what it is. Emphasizes the development of the scientific method of problem solving. Students develop a hypothesis (from experimentation) about the inner configuration of an Ob-Scertainer® by indirect observation. They test their hypothesis and make a new one, if necessary. The students continue to experiment and can actually verify their hypothesis if so desired. The kit consists of 24 opaque chambers (two each of 12 different interior structures) and steel balls. This reusable kit can be used by 24 students simultaneously.
