Give examples of applications of genetic engineering. Students investigate and give evidence that populations and their environment change over long periods of time. 7.1.12-a Explain how genetic variations in offspring can result from the same two parents, which leads to variation in successive generations. Demonstrate how changes in the environment can bring about changes in species through processes of mutation, natural selection, adaptation, and extinction. 7.1.12-c Describe and explain how fossils are records of events in Earth's history.
Students use a classification system to group and identify organisms.
7.1.13-a Recognize that living things are classified based on similarities and differences in their internal and external structures. 7.1.13-b Identify characteristics of representatives of the five kingdoms and recognize that they are subject to change. 7.1.13-d Use a dichotomous key to identify organisms. Standard 2 Apply science knowledge and skills to make informed decisions and to solve problems. Students apply problem-solving skills when gathering, analyzing, and interpreting scientific information.
