By exploring asexual and sexual reproduction in both plants and animals, students are able to develop a broader understanding of reproductive systems, growth, and changes. Students can demonstrate their knowledge of reproduction in diagrams, concept maps, and written summaries. Students demonstrate their scientific skills and processes when they design experiments, select appropriate procedures, and make conclusions based on collected data. Physical Science Physical Science is the study of matter and energy, and their interactions. By using the skills, processes, and attitudes of science, students build a foundation for their understanding of the physical world.
Some chemical changes occur naturally in the environment.
Others may be produced from the human use of products and processes that result in pollution, environmental destruction, and ultimately may involve some level of risk to human health or to the survival of other organisms. By exploring fertilizers, pesticides, acid rain, the nitrogen cycle, the carbon cycle, the water cycle, and other types of chemical reactions in the local environment, students begin to distinguish between those chemical reactions that are beneficial and those that are harmful. Through collecting, analyzing, and interpreting data on environmental quality, students begin to assess the impact of chemical pollution on the local environment and suggest ways of solving these problems. Students can demonstrate their knowledge of chemical reactions in oral and written reports, diagrams, and charts. Students demonstrate their scientific skills and processes when they conduct and report on scientific investigations and analyses of environmental issues.
