Students read short stories about how scientists used the scientific method to solve real problems. In one case, Dr. Eijkman used observation to notice that chickens who ate polished rice became sick with beriberi. Further studies lead to the conclusion that a vitamin deficiency could make chickens and humans sick. After reading the story, students identify the hypothesis, how the hypothesis was tested, and what conclusions were reached as a result of the experiment.
