Answers to Science
Answers to Science and Society

As the name implies, this quiz probes the students' abilities to carry out analytic thought on the subject matter learned in this module. Student answers will vary, so the answers presented here are given merely as guidelines for assessing the students' responses.

Relevant National Science Education Standards

Unifying Concepts and Processes — The students' understanding of many systems are probed in the questions, from the workings of molecules to massive systems like the atmosphere. The students are asked to cite evidence to support statements (see Science Question 4).

Physical Science — The molecular structure of matter, chemical reactions, and the interactions of energy and matter on the molecular level are central to many of the questions.

Earth and Space Science — Knowledge of energy in the earth system (in the form of UV radiation) and the geochemistry of ozone depletion are essential in order to answer the questions.

Science and Technology — The limits of the abilities of technological design are evident in the questions which are centered on the flawed technology of CFC refrigerants.

Science in Personal and Social Perspectives — Environmental quality, human induced hazards, and the role science and technology in the global challenge of addressing ozone depletion are the topics around which the questions revolve.

History and Nature of Science — Knowledge of the lives and careers of Molina and Francisco are necessary to answer the questions, as is historical knowledge of how CFCs came to be used in the first place.
