Biology Chapter 1 The Science Of Biology

1. Section 1 What is Science?

   • Key Questions
     • What are the goals of science?
       • Science aims to supply natural explanations for events in the natural world.
         • It also aims to understand patterns in nature and make useful predictions.
     • Procedures at the core of scientific methodology?
       • 1. observing, asking questions 2. making inferences, forming hypotheses 3. controlled experiments
         • 4. collecting and analyzing data 5. drawing conclusions
   • Vocabulary
     • science, observation, inference, hypothesis, controlled experiment,
       • independent variable, dependent variable, control group, data

2. Section 2 Science in Context

   • Key Questions
     • Scientific attitudes that help generate new ideas?
       • Curiosity, skepticism, having an open mind, and creativity
         • All of these characteristics are vital in developing new ideas.
     • Importance of peer review
       • Peer reviewed articles that are published in scientific journals
         • allow ideas to be shared, tested, and evaluated.
     • What is scientific theory?
       • A well-tested explanation that unifies a broad range of
         • observations and hypotheses. It also enables scientists
           • to make accurate predictions about new situations.
     • The relationship between science and society.
       • Science both influences society and is influenced by society.
         • Using science involves understanding its context in society and its limitations
   • Vocabulary
     • theory, bias

3. Section 3 Studying Life

   • Key Questions
     • Characteristics all living things share.
       • Made up of cells, based on a universal genetic code, obtain and
         • and use materials and energy, grow and develop, reproduce,
           • respond to their environment, homeostasis, and change over time.
     • Central themes of biology?
       • Cellular basis of life; information and heredity;
         • 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.
     • Differing ways fields of biology study life.
       • Biology includes many overlapping fields that use
         • different tools to study life from the level of
           • molecules to the entire planet.
     • Metric system important to science.
       • Most scientists use the metric system when
         • collecting data and performing experiments.
   • Vocabulary
     • biology, DNA, stimulus, sexual and asexual reproduction
       • homeostasis, metabolism, biosphere,
