The activities require two 45-minute periods. They are designed for use in grades 9 through 12. This activity is adapted with permission from Evolution Inquiries into Biology and Earth Science by BSCS.9 Standards-Based Outcomes This activity provides opportunities for all students to develop abilities of scientific inquiry as described in the National Science Education Standards. Specifically it enables them to formulate descriptions explanations predictions and models using evidence think critically and logically to make relationships between evidence and explanations and recognize and analyze alternative explanations and predictions. In addition the activity provides all students opportunities to develop fundamental understandings in the life sciences as described in the National Science Education Standards. Specifically it conveys the following concepts In all organisms the instructions for specifying the characteristics of the organism are carried in DNA a large polymer formed from subunits of four kinds A G c and T . The chemical and structural properties of DNA explain how the genetic information that underlies heredity is both encoded in genes as a string of molecular letters and replicated by a templating mechanism . The millions of different species of plants animals and microorganisms that live on earth today are related by descent from common ancestors. Biological classifications are based on how organisms are related. Organisms are classified into a hierarchy of groups and subgroups based on Copyright 2004 National Academy of Sciences.
