      Strategies: Additional Instruction and Practice

      The following activities are suggestions for working with students who need additional instruction and practice. We hope that the activities spark ideas and conversations among teachers about useful classroom strategies that can supplement existing curriculum.

      Activity 1

      Genetics Timeline

      Click here* for a student-friendly timeline from DNA Interactive that charts the development of scientific knowledge relevant to the field of genetics .

      Students may use information from this Web site and related online and print resources to trace how scientific understanding of DNA has changed over time, almost always building on earlier knowledge (Scientific Ways of Knowing, Benchmark B). Using additional information from these resources, students should also justify how past and present theories about DNA are explanations of observations that withstand repeated testing. Students may present their findings to the class. Skills in this lesson also address student understanding of the genetic mechanisms and molecular basis of inheritance (Life Sciences, Benchmark C).

      Activity 2

      Becoming a Scientist

      Click here* for "Becoming a Scientist," a series of videos from the Howard Hughes Medical Institute in which biomedical researchers describe what qualities one needs to be successful in biomedical research. Students should discuss what they believe are the essential qualities of a scientific researcher and compare their answers with those of the speakers.

      Students should be able to illustrate that much can be learned from the study of scientists and their efforts to advance scientific knowledge (Scientific Ways of Knowing, Benchmark D). They also should explain how scientific inquiry is guided by knowledge, observations, ideas and questions (Scientific Ways of Knowing, Benchmark B).
