Biology Chapter 1 The Science Of Biology

Section 1 What is Science?
1. Key Questions
  1. What are the goals of science?
    1. Science aims to supply natural explanations for events in the natural world.
      1. It also aims to understand patterns in nature and make useful predictions.
  2. Procedures at the core of scientific methodology?
    1. 1. observing, asking questions 2. making inferences, forming hypotheses 3. controlled experiments
      1. 4. collecting and analyzing data 5. drawing conclusions
2. Vocabulary
  1. science, observation, inference, hypothesis, controlled experiment,
    1. independent variable, dependent variable, control group, data
Section 2 Science in Context
1. Key Questions
  1. Scientific attitudes that help generate new ideas?
    1. Curiosity, skepticism, having an open mind, and creativity
      1. All of these characteristics are vital in developing new ideas.
  2. Importance of peer review
    1. Peer reviewed articles that are published in scientific journals
      1. allow ideas to be shared, tested, and evaluated.
  3. What is scientific theory?
    1. A well-tested explanation that unifies a broad range of
      1. observations and hypotheses. It also enables scientists
        to make accurate predictions about new situations.
  4. The relationship between science and society.
    1. Science both influences society and is influenced by society.
      1. Using science involves understanding its context in society and its limitations

    1. Made up of cells, based on a universal genetic code, obtain and
      1. and use materials and energy, grow and develop, reproduce,
        respond to their environment, homeostasis, and change over time.
  2. Central themes of biology?
    1. Cellular basis of life; information and heredity;
      1. matter and energy; growth, development, and reproduction;
        homeostasis; evolution; structure and function;
        unity and diversity of life; interdependence in nature;
        and science as a way of knowing.
  3. Differing ways fields of biology study life.
    1. Biology includes many overlapping fields that use
      1. different tools to study life from the level of
        molecules to the entire planet.
  4. Metric system important to science.
    1. Most scientists use the metric system when
      1. collecting data and performing experiments.
