The film illustrates many of the practices of science, including asking important questions, formulating and testing hypotheses, analyzing and interpreting evidence, and revising explanations as new evidence becomes available.
This version of the film pauses at four points where students answer questions about the film to assess their understanding of the concepts presented. After completing all quiz modules, students can view and print their answers.
