21 Evolutionary change links all forms of life to a common origin more than 3.5 billion years ago. True or False True

22 All forms of life are connected into a __________, which means “living planet.” Fill in the Blank biosphere

23 The factor of a system being investigated that is changed to determine that factor’s relationship to the responding variable. Multiple Choice A.Prediction B.Control group C.Controlled variable D.Manipulated variable

24 The prefix that means 1000 is milli. True or False False The prefix that means 1000 is kilo.

25 Most scientists use the ________ system when gathering data and doing experiments. Fill in the Blank metric

26 Mistakes of perception, measurement, or process during an investigation; an incorrect result or discrepancy. Multiple Choice A.Cause B.Observation C.Inference D.Error

27 When scientists explain “why” something happens, their explanation is about only nature. Science does not include ethical or moral views. True or False True

28 Sometimes, _______ keeps scientists from doing certain kinds of experiments, such as cloning people. Fill in the Blank ethics

29 Observations, measurements, or data collected through established and recognized scientific processes. Multiple Choice A.Evidence B.Hypotheses C.Theories D.Consequences

30 Controlled experiments typically involve testing two or more variables at a time. True or False False Controlled experiments involve testing only one variable at a time.

31 In the leaf toughness experiment, the leaf’s exposure to sunlight was the ____________ variable and how easily the leaf ripped was the ___________ variable. Fill in the Blank manipulated responding

32 The factor of a system being investigated that changes in response to the manipulated variable and is measured. Multiple Choice A.Quantitative data B.Responding variable C.Controlled variable D.Qualitative data

33 Placing the rip-o-meter’s binder clip in the same position on each leaf tested is an example of a controlled variable. True or False True

34 Comparing the toughness of leaves as a function of branch position was best graphed using a ___________________ chart. Fill in the Blank Scatter plot

35 The conditions that are kept the same from trial to trial in a laboratory investigation. Multiple Choice A.Controlled variables B.Responding variable C.Manipulated variable D.Quantitative data

36 In the leaf toughness lab, a strong correlation was found between branch position and ease of ripping. True or False False In the leaf toughness lab, no correlation was found between branch position and ease of ripping.

37 In the leaf toughness lab, we can __________ from the data that our hypothesis, which stated that older leaves would be tougher to rip than younger leaves, was not supported by the evidence. Fill in the Blank conclude

38 An investigation under which the conditions for a phenomenon to occur are arranged beforehand by the investigator. Multiple Choice A.Variable B.Experiment C.Trial D.Effect

39 A strong correlation implies causation. True or False False Remember the example about shoe size and math ability among children showing a strong correlation, but certainly no causation.

44 Data that consists of numbers that are found by measuring or counting. Multiple Choice A.Variables B.Qualitative C.Quantitative D.Sources of Error

45 Data that consists of descriptions because they cannot be counted. Multiple Choice A.Variables B.Qualitative C.Quantitative D.Measurements
