The Scientific Method Test and Practice Test includes 20 pages along with the answer key. The focus of the test is to assess student understanding of the scientific process, variables and controls, and evaluating the accuracy and reproducibility of data. I prepare my students by having them work on the practice test in groups of up to four students. I give the group leader the answer key for the practice test to help them facilitate discussion of the correct answer. This strategy has proven to be effective in my classroom and has greatly increased student understanding of the scientific method.
