This course introduces students to the study of the life sciences. The ultimate goal is to produce students who are more scientifically literate and environmentally aware; therefore, the curriculum addresses attitudes, processes, knowledge science, technology, society, the environment, and careers. Topics covered include the nature of science, the structure and function of the cell, chemistry of living organisms, genetics, nucleic acid formation and function, taxonomy, a study of the characteristics of the six kingdoms of organisms, origin and diversity of life, and ecological relationships. Various laboratory investigations and other activities strengthen the mastery of topics covered.
- Understanding Organization and Development: Living organisms are composed of cellular units (structures) that carry out functions required for life. Cellular units are composed of molecules, which also carry out biological functions.
- Understanding Matter and Energy Transformations: Food is required for energy and building cellular materials. Organisms in an ecosystem have different ways of obtaining food, and some organisms obtain their food directly from other organisms. All animals and most plants depend on both other organisms and their environment to meet their basic needs.
- Understanding Heredity and Reproduction: Organisms reproduce, develop, and have predictable life cycles. Organisms contain genetic information that influences their traits, and they pass this on to their offspring during reproduction.
- Understanding Evolution and Diversity: Sometimes, differences between organisms of the same kind provide advantages for surviving and reproducing in different environments. These selective differences may lead to dramatic changes in characteristics of organisms in a population over extremely long periods of time.
- Understanding Science Practices:
- Understand Scientific Explanations: Students understand core concepts and principles of science and use measurement and observation tools to assist in categorizing, representing, and interpreting the natural and designed world.
- Generate Scientific Evidence Through Active Investigations: Students master the conceptual, mathematical, physical, and computational tools that need to be applied when constructing and evaluating claims.
- Reflect on Scientific Knowledge: Scientific knowledge builds on itself over time.
- Participate Productively in Science: The growth of scientific knowledge involves critique and communication, which are social practices that are governed by a core set of values and norms.
