Unit 1 Cornell Notes Lesson 1 EQ: Obj: Name __________________________________________ Per ___ What is science? How is science different from other fields of study? SWBAT.. Distinguish what characterizes science and scientific explanations from other forms of knowledge and recognize creativity in science. What does science study? Natural events and conditions. The Natural world: biology – life Geology – earth Astronomy/ Earth – outer space Physical – energy and all nonliving matter Testable ideas – results are measured and compared and can be proven wrong. What is a scientific explanation? It describes a natural process. It relies heavily on evidence gained from direct observation and testing. Others can test it and prove it wrong. Based on Empirical evidence - observations, measurements, and other types of data scientists gather by using their 5 senses: hearing, sight, smell, taste or touch How is scientific explanation evaluated? Look at the empirical evidence. Is the explanation logical? What other tests could you do to support it? Evaluate the explanation. How do scientists show creativity? In designing experiments. In explaining observations. Lesson 2 EQ: Obj: Scientific Knowledge How do we know about the world we live in? SWBAT.. identify examples of scientific knowledge and describe how they may change with new evidence. Theories – well supported explanation about the natural world. What are some Survived a lot of testing. types of scientific Explain observations; can be used to make predictions. explanations? Example: plate tectonics Models – representation of something in the natural world that is too large, too small, or difficult to study. Can be physical, math equation, or computer program Anything familiar that helps scientists understand anything not familiar. Can represent past, present, and future events. Laws- describes a basic principle of nature that always occurs under certain conditions. Example: law of gravity What makes good scientific knowledge? It can adapt to explain new observations. What makes a good source? Good source: any place that relies on its reputation; government, university, or nationally recognized research institutions. (NASA, Mayo Clinic) Bad source: anyone trying to sell you something, old publications Lesson 3 EQ: Obj: Scientific investigations How do scientists work? SWBAT.. summarize the processes and characteristics of different kinds of scientific investigations. What are some types of scientific investigations? Experiments Observations – information from our senses Create a model What are some parts that make up scientific investigations? Purpose – problem or question Research Hypothesis – educated guess about results What are the parts of the scientific method? Experiment – step by step, reproducible Analyze observations and data Conclusion What are some ways to confirm that an investigation is valid? Peer review - other scientists look at it How can you evaluate the quality of scientific information? Most reliable is published in scientific journals or from government or academic webpages. Replication – other scientist repeat it and get the same results. Lesson 4 EQ: QBJ: Representing Data In what ways can you organize data to fully understand them? SWBAT.. use tables, graphs, and models to display and analyze scientific data. How do scientists make sense of data? Organize data into tables What do graphs show? A visual representation of data. What types of models can be used to represent data? Physical models – you can touch Toy cars, models of buildings, maps, globes They represent things to small or large to see. Graph and analyze the data Mathematical Models Speed = Distance / Time What are some benefits and limitations of models? Benefits - they allow scientists to change variables without affecting or harming the subject that they are studying. Crash-test dummies study the effects of car accidents on people. Limited - information is left out Lesson 5 EQ: OBJ: Science and Society How does science affect our lives? SWBAT.. describe the impact that science has had on society and the role of scientists throughout history and today. What does science affect? The way we think. The way we live our lives. Medicines, technology, transportation, foods Who contributes to science? People who contribute to science come from all backgrounds, fields of interest, and skill groups. Those who do scientific research People in many fields Conclusion: using your Cornell notes, answer each of the following questions with at least 2 complete sentences. Remember to check for three: spelling, punctuation, and capitalization. 1. How is science different from other fields of study? Science explains the natural world. Science depends on testable ideas and empirical evidence. Scientists are creative when they design experiments and explain their observations. 2. How do we know about the world we live in? We know about the world we live in by reading, and making observations. Theories, models, and laws help us explain things that happen in nature and can adapt to explain new observations. 3. How do scientists work? Scientists do experiments, make observations and create models to help solve problems or answer questions about the natural world. Scientists follow the scientific method; identify a problem, research, make a hypothesis, experiment, analyze observations and data and come to a conclusion. 4. In what ways can you organize data to fully understand them? Scientists organize data into data tables, graphs, and models so they can analyze it. Models can be physical, mathematical or computer models. 5. How does science affect our lives? Science affects the way we think and how we live our lives. Science has improved medicines, technology, transportation and foods.
