Science is a process for producing knowledge methodically and logically TERM 2 Ideally, science DEFINITION 2 is orderly and methodically TERM 3 Which of the following is NOT an important feature of science DEFINITION 3 positive proof TERM 4 Generally, distinguished scientists DEFINITION 4 may have different interpretations of the same evidence TERM 5 Proof in science is always DEFINITION 5 open to question or new evidence
The statement " Since every insect I have examined so far has six legs, I conclude that all insects have six legs" is an example of Inductive reasoning TERM 7 Although your sister is not a scientist, she says that she uses scientific techniques in her everyday life. You do not believe her but she insists it is True. Which of the examples could she use to best persuade you? DEFINITION 7 She puts some tomatoes in the sun and some in the shade to see if the sun causes them to ripen faster TERM 8 Experiments in which conditions are deliberately altered and all other variable are held constants are known as ______ experiments DEFINITION 8 Manipultive TERM 9 Double-blind studies are studies are especially useful in DEFINITION 9 Health studies TERM 10 In experimentation, dependent variables are also known as ________ variables DEFINITION 10 Response
Paradigm shifts occur when ethical considerations are incorporated into scientific theory True or False False TERM 17 Results must be somewhat repeatable and these results that only work for this researcher do not qualify as science DEFINITION 17 A researcher reports he has conducted manny experiments where a galvanometer (lie detector) was hooked up to detect the plant's response. He reports that a spider was released near the plant, the spider's decision to escape was up by the plant, "causing a reaction in the leaf." When other researchers repeated the experiment, they could not get any galvanometer responses. The researcher then concluded that plants could be put into a faint by humans. TERM 18 This is an scientific procedure, although it does lack a stated hypothesis describing an anticipated outcome. DEFINITION 18 An elementary student decides to conduct an experiment comparing the effectiveness of two commercial soaps as cleaning agents, using each in paired tests of different types of stains and colors of cloth, where the only variable is the soap used. The student will use the judgment of classmates to decide if the stains remain equal or if soap one cleans better than the other in each test run. TERM 19 What is inductive reasoning? DEFINITION 19 using isolated observations and facts a general idea that may explain phenomenon TERM 20 What is deductive reasoning? DEFINITION 20 a general statement made to infer a specific conclusion, often in, "if...then" format
What is a Hypothesis? a tentative statement, based on data, that can be used to guide further observation and experiments TERM 22 Which statement is NOT True about hypothesis? DEFINITION 22 A hypothesis cannot be proven TERM 23 Which best describes a control group in a experiment? DEFINITION 23 a sample taken through all experimental steps except the one being tested TERM 24 Four groups of mice consume different amounts of sweetener in their food. The control group is the one that receives DEFINITION 24 no sweetener TERM 25 Which statement is NOT true about experimental design? DEFINITION 25 the condition being tested in an experiment is the control variable
For five years, you wake up before the alarm is set to ring each morning. This leads you to conclude that people have built-in "alarm clock" capable of the eating them up. From a science viewpoint, this conclusion may not be valid because it generalizes about all people, and there may have been other variables that could awaken you without a built-in clock. TERM 32 Which statement is NOT true about science? DEFINITION 32 Science approaches data in a subjective manner. TERM 33 Experimental design DEFINITION 33 is the way in which the scientist intends to conduct an experiment ensures that scientists are testing what they want to test ensures that the test results are meaningful (all of the choices are correct) TERM 34 Science is only concerned with understanding and explaining the natural world. true or false DEFINITION 34 TRUE TERM 35 A hypothesis is formulated from observations or experimental data to explain the data and to serve as a guide for further research. true or false DEFINITION 35 TRUE
Scientific observations should be made in a subjective manner. true or false False TERM 37 The control group in an experiments the one that shows the dependent variable true or false DEFINITION 37 FALSE TERM 38 The control group in an experiment is given all the same treatments as the experimental group(s), except for the one variable being tested. true or false DEFINITION 38 TRUE TERM 39 It is important that an experimental procedure include a control group where possible true or false DEFINITION 39 TRUE TERM 40 In an experiment testing sweetener in the diet of mice, the control group is one that has the most sweetener true or false DEFINITION 40 FALSE
