Chapter 1.1 – What is Science?
![Page 2: Chapter 1.1 What is Science? - Moore Public Schools 1.1 –What is Science? ... • Inferences can help to form a hypothesis. Thinking Like a Scientist • A hypothesis is a proposed](https://reader033.vdocuments.mx/reader033/viewer/2022051509/5b08c6257f8b9abe5d8ba124/html5/thumbnails/2.jpg)
• State and explain the goals of science.
• Describe the steps used in the scientific method.
Daily Objectives
![Page 3: Chapter 1.1 What is Science? - Moore Public Schools 1.1 –What is Science? ... • Inferences can help to form a hypothesis. Thinking Like a Scientist • A hypothesis is a proposed](https://reader033.vdocuments.mx/reader033/viewer/2022051509/5b08c6257f8b9abe5d8ba124/html5/thumbnails/3.jpg)
• Investigate and understand the natural world.
• Explain events in the natural world.
• Use those explanations to make useful predictions.
The Goals of Science are to:
![Page 4: Chapter 1.1 What is Science? - Moore Public Schools 1.1 –What is Science? ... • Inferences can help to form a hypothesis. Thinking Like a Scientist • A hypothesis is a proposed](https://reader033.vdocuments.mx/reader033/viewer/2022051509/5b08c6257f8b9abe5d8ba124/html5/thumbnails/4.jpg)
• Science deals only with the natural world.
• Scientists collect and organize information in a careful, orderly way .
• Scientists propose explanations that can be tested by examining evidence.
What Makes Science Unique
![Page 5: Chapter 1.1 What is Science? - Moore Public Schools 1.1 –What is Science? ... • Inferences can help to form a hypothesis. Thinking Like a Scientist • A hypothesis is a proposed](https://reader033.vdocuments.mx/reader033/viewer/2022051509/5b08c6257f8b9abe5d8ba124/html5/thumbnails/5.jpg)
• Science is an organized way of using evidence to learn about the natural world.
What Science Is and Is Not
![Page 6: Chapter 1.1 What is Science? - Moore Public Schools 1.1 –What is Science? ... • Inferences can help to form a hypothesis. Thinking Like a Scientist • A hypothesis is a proposed](https://reader033.vdocuments.mx/reader033/viewer/2022051509/5b08c6257f8b9abe5d8ba124/html5/thumbnails/6.jpg)
• Scientific thinking begins with observation.
• Observation is the process of gathering information about events or processes in a careful, orderly way.
• Observation generally involves using the senses.
Observing and Asking Questions
![Page 7: Chapter 1.1 What is Science? - Moore Public Schools 1.1 –What is Science? ... • Inferences can help to form a hypothesis. Thinking Like a Scientist • A hypothesis is a proposed](https://reader033.vdocuments.mx/reader033/viewer/2022051509/5b08c6257f8b9abe5d8ba124/html5/thumbnails/7.jpg)
• After making observations scientists can make inferences.
• An inference is a logical interpretation based on prior knowledge or experience.
• Inferences can help to form a hypothesis.
Thinking Like a Scientist
![Page 8: Chapter 1.1 What is Science? - Moore Public Schools 1.1 –What is Science? ... • Inferences can help to form a hypothesis. Thinking Like a Scientist • A hypothesis is a proposed](https://reader033.vdocuments.mx/reader033/viewer/2022051509/5b08c6257f8b9abe5d8ba124/html5/thumbnails/8.jpg)
• A hypothesis is a proposed scientific explanation for a set of observations.
• A hypothesis may be ruled out or confirmed.
Inferring and Forming a Hypothesis
![Page 9: Chapter 1.1 What is Science? - Moore Public Schools 1.1 –What is Science? ... • Inferences can help to form a hypothesis. Thinking Like a Scientist • A hypothesis is a proposed](https://reader033.vdocuments.mx/reader033/viewer/2022051509/5b08c6257f8b9abe5d8ba124/html5/thumbnails/9.jpg)
• Hypotheses are tested by performing controlled experiments.
Explaining and Interpreting Evidence
![Page 10: Chapter 1.1 What is Science? - Moore Public Schools 1.1 –What is Science? ... • Inferences can help to form a hypothesis. Thinking Like a Scientist • A hypothesis is a proposed](https://reader033.vdocuments.mx/reader033/viewer/2022051509/5b08c6257f8b9abe5d8ba124/html5/thumbnails/10.jpg)
• The factors that change in an experiment are called variables
• Only one variable should be changed during the experiment
• All other variables should be kept unchanged, or controlled.
Designing Controlled Experiments
![Page 11: Chapter 1.1 What is Science? - Moore Public Schools 1.1 –What is Science? ... • Inferences can help to form a hypothesis. Thinking Like a Scientist • A hypothesis is a proposed](https://reader033.vdocuments.mx/reader033/viewer/2022051509/5b08c6257f8b9abe5d8ba124/html5/thumbnails/11.jpg)
• If several variables are changed in the experiment, researchers can’t tell which variable is responsible for any results they observe.
• The variable that is deliberately changed is called the independent variable
• The variable that is observed and that changes in response to the independent variable is called the dependent variable
Designing Controlled Experiments
![Page 12: Chapter 1.1 What is Science? - Moore Public Schools 1.1 –What is Science? ... • Inferences can help to form a hypothesis. Thinking Like a Scientist • A hypothesis is a proposed](https://reader033.vdocuments.mx/reader033/viewer/2022051509/5b08c6257f8b9abe5d8ba124/html5/thumbnails/12.jpg)
• The information gathered from observations is called data.
• Quantitative: Numbers (measurements)
• Qualitative: Descriptive and usually can’t be counted
Data
![Page 13: Chapter 1.1 What is Science? - Moore Public Schools 1.1 –What is Science? ... • Inferences can help to form a hypothesis. Thinking Like a Scientist • A hypothesis is a proposed](https://reader033.vdocuments.mx/reader033/viewer/2022051509/5b08c6257f8b9abe5d8ba124/html5/thumbnails/13.jpg)
• Scientists use experimental data as evidence to support, refute, or revise the hypothesis being tested, and to draw a valid conclusion.
Drawing Conclusions
![Page 14: Chapter 1.1 What is Science? - Moore Public Schools 1.1 –What is Science? ... • Inferences can help to form a hypothesis. Thinking Like a Scientist • A hypothesis is a proposed](https://reader033.vdocuments.mx/reader033/viewer/2022051509/5b08c6257f8b9abe5d8ba124/html5/thumbnails/14.jpg)
• Science is an ongoing process that involves:
• Asking questions
• Observing
• Making inferences
• Testing hypotheses
Science as a Way of Knowing
![Page 15: Chapter 1.1 What is Science? - Moore Public Schools 1.1 –What is Science? ... • Inferences can help to form a hypothesis. Thinking Like a Scientist • A hypothesis is a proposed](https://reader033.vdocuments.mx/reader033/viewer/2022051509/5b08c6257f8b9abe5d8ba124/html5/thumbnails/15.jpg)
• Because of new knowledge gained through research, scientists continually revise and reevaluate their ideas
• An understanding of science and the scientific approach is essential to making intelligent decisions about many important topics.
