Science addresses questions about the natural and material world through the systematic study of these events and conditions. People are naturally curious individuals who often wonder how and why something happens in the world around them. Science is the processes for seeking the answers and creating explanations for these questions. 2. Science is a way of knowing. Science is an attempt to explain natural phenomena through scientific explanations, which provide a description of how processes in nature occur. Explanations must be based on observations and data collected and are an attempt to logically explain how the pieces of evidence fit together. While durable, scientific knowledge has a tentative nature and is subject to change. 3. Scientific Investigations use a variety of methods. There is no “one” way to do science, therefore, there is no universal step-by-step scientific method. This requires scientists to be curious, imaginative, creative, and careful observers who are also logical, skeptical, and objective. 4. Scientific Knowledge is based on empirical evidence. It includes all data that is observed and measured that people gather to test, support, and evaluate explanations. Scientific knowledge relies heavily, but not entirely on observation, experimental evidence, rational arguments, and skepticism. 5. Scientific knowledge is open to revision in light of new evidence. Scientific ideas must be testable, reproducible and open for peer review (data must be available for other scientists to comment on). Scientists must collaborate, share, discuss, question and debate ideas to agree upon scientific knowledge. Scientific knowledge builds in both an evolutionary and revolutionary way and it is subject to change if new evidence is found or someone found a better way of explaining the evidence. 6. Scientific models, laws, mechanisms and theories explain natural phenomenon. Scientific laws are descriptions of a specific relationship under a given condition in the natural world which hold true anywhere in the universe. A scientific theory is a well-supported explanation of nature, to help us understand and explain the laws we observe. Theories never become laws, even with additional evidence. 7. Science is a human Endeavor. Scientists are people, both men and women who conduct scientific research that affects the way we think and the way we live our lives. People from all cultures contribute to science causing it to be both socially and culturally embedded in traditions. Scientific ideas are affected by social and historical settings, while technology and science also affect each other. 8. Scientific knowledge assumes an order and consistency in natural systems. Scientific knowledge is based on the assumption that natural laws operate today as they did in the past and they will continue to do so in the future. It assumes that objects and events in natural systems occur in consistent patterns that are understandable through measurement and observation. Science carefully considers and evaluates anomalies in data and evidence.

Asking Questions and Defining Problems Science begins with a question about a phenomenon, such as “Why is the sky blue?” or “What causes cancer?” and seeks to develop theories that can provide explanatory answers to such questions. 5. Using Mathematics and Computational Thinking In science, mathematics and computation are fundamental tools for representing physical variables and their relationships. They are used for a range of tasks, such as constructing simulations, statistically analyzing data, and recognizing, expressing, and applying quantitative relationships. 2. Developing and Using Models Science often involves the construction and use of a wide variety of models and simulations to help develop explanations about natural phenomena. Models make it possible to go beyond observables and imagine a world not yet seen. Models enable predictions of the form “if . . . then . . . therefore” to be made in order to test hypothetical explanations. 3. Planning and Carrying Out Investigations A major practice of scientists is planning and carrying out a systematic investigation, which requires the identification of what is to be recorded and, if applicable, what are to be treated as the dependent and independent variables (control of variables). Observations and data collected from such work are used to test existing theories and explanations or to revise and develop new ones. 4. Analyzing and Interpreting Data Scientific investigations produce data that must be analyzed in order to derive meaning. Because data usually do not speak for themselves, scientists use a range of tools— including tabulation, graphical interpretation, visualization, and statistical analysis—to identify the significant features and patterns in the data. 6. Constructing Explanations and Designing Solutions: The goal of science is the construction of theories that can provide explanatory accounts of features of the world. The goal for students is to construct logically coherent explanations of phenomena that incorporate their current understanding of science, or a model that represents it, and are consistent with the available evidence. 7. Engaging in Argument from Evidence: In science, reasoning and argument are essential for identifying the strengths and weaknesses of a line of reasoning and for finding the best explanation for a natural phenomenon. Scientists must defend their explanations, formulate evidence based on a solid foundation of data, examine their own understanding in light of the evidence and comments offered by others, and collaborate with peers in searching for the best explanation for the phenomena being investigated. 8. Obtaining, Evaluating, & Communicating Info Science cannot advance if scientists are unable to communicate their findings clearly and persuasively or to learn about the findings of others. A major practice of science is thus the communication of ideas and the results of inquiry—orally, in writing, with the use of tables, diagrams, graphs, and equations, and by engaging in extended discussions with scientific peers.
