Chapter 1, Section 2 Answers to review for worksheet pages Study Notes with Answers Cited from Pearson Education, Inc. Publishing as Pearson Hall workbook and textbook. For classroom use only.

2 Key Terms to Know Scientific inquiry – A process that includes the different ways that scientists find out about the natural world and try to explain what they have observed. Hypothesis – One possible answer to a scientific question. Variable – Something that can change in an experiment.

3 Key Terms to Know – continued…
Manipulated Variable or also called the Independent Variable (IV) – The variable that is changed on purpose during an experiment to test a hypothesis. Responding Variable or also called the Dependent Variable (DV) – The variable that changes in response to changes in the manipulated variable.

4 Key Terms to Know – continued…
Controlled Experiment – An experiment in which only one variable is manipulated. Operational Definition – A description of how to measure a variable or define a term within a controlled experiment. Data – Facts, figures, and other evidence that a scientists collects through observing.

5 Key Terms to Know – continued…
Communicating – The ways in which scientists share ideas and experimental results with other scientists. Scientific theory – A single explanation that connects a large set of related observations or results from experiments. Scientific law – A rule of nature that describes what scientists suppose will happen every time when conditions are the same.

6 Introduction - What does scientific inquiry refer to?
Scientific theory refers to the diverse ways in which scientist study the natural world and propose explanations based on the evidence they gather.

7 Posing Questions Is the following sentence true or false? Scientific inquiry often begins with developing a hypothesis. FALSE Circle the letter of each sentence that is a scientific question. At which temperature does water boil? When does the sun rise on April 3? How can my team work better together? Why does she like science more than he does?

8 Developing Hypotheses
A (n) hypothesis is a possible explanation for a set of observations or answer to a scientific question. Is the following sentence true or false? Scientists consider a hypothesis to be a fact. _____true or false ___ What is a testable hypothesis? A hypothesis for which researchers can carry out investigations and gather evidence that will either support or disprove the hypothesis.

9 Designing an Experiment
To test a hypothesis, a scientist designs a (n) experiment. GO TO THE NEXT PAGE FOR MATCHING TERMS->

10 Designing an Experiment
Match the term with its definition. D 8. responding variable A 9. operational variable B 10. manipulated variable E 11. controlled experiment C 12. variable 13. Is the following sentence true or false? If you did not control variables in an experiment, there would be no way to know which variable explained your results. TRUE

11 Collecting and Interpreting Data
The facts, figures, and other evidence gathered through observations are called data. In carrying out a controlled experiment, what does a data table help you do? A data table provides you an organized way to collect and record your observations.

12 Collecting and Interpreting Data
Circle the letter of each sentence that is true about graphs. A graph can reveal a trend in data. Graphs help scientists interpret data. Graphs are the only way to organize data. A graph can reveal a pattern in data.

13 Drawing Conclusions A (n) conclusion is a summary of what you have learned from an experiment. 18. What do you ask yourself in drawing a conclusion about an experiment? Whether the data support the hypothesis.

14 The Nature of Inquiry Complete the Nature of Inquiry diagram by filling in the blanks. The Nature of Inquiry Pose Questions Form a hypothesis Draw conclusions Design an experiment Collect and interpret data

15 The Nature of Inquiry Why is scientific inquiry a process with many paths, not a rigid sequence of steps? Different questions may require different approaches to finding answers.

16 Communicating In scientific inquiry, what is communicating?
The sharing of ideas and experimental findings with other through writing and speaking. Circle the letter of the sentence that explains why scientists describe their research in full when they communicate with other scientists. B. Other scientists need to be able to repeat a scientist’s experiments.

17 Scientific Theories and Laws
What is a scientific theory? A well tested explanation for wide range of observations or experimental results. Is the following sentence true or false? Future testing can prove a scientific theory to be incorrect. TRUE You can think of a (n) scientific law as a rule of nature.

18 Scientific Theories and Laws
How is a scientific law unlike a scientific theory? Unlike a scientific theory, a scientific law describes an observed pattern in nature without attempting to explain it.
