Question

1. match the sentences with the words. this is one part of an experiment that should be changed to observe what happens. scientists collect this information during an experiment. this is formed when a scientist asks a question and then states a possible answer. investigators write out the detailed steps of an experiment before beginning. this should not change in an experiment.

Explanation:

To solve this matching problem, we analyze each description and identify the corresponding scientific term:

1. "This is one part of an experiment that should be changed to observe what happens." → Independent Variable (the variable manipulated in an experiment).
2. "Scientists collect this information during an experiment." → Data (information gathered from experiments).
3. "This is formed when a scientist asks a question and then states a possible answer." → Hypothesis (a testable prediction for a scientific question).
4. "Investigators write out the detailed steps of an experiment before beginning." → Procedure (the step - by - step plan of an experiment).
5. "This should not change in an experiment." → Constant (factors kept the same to ensure a fair test) or Dependent Variable (if considering what's measured, but "constant" fits the "should not change" description better).

If we assume the words to match are from a typical scientific method vocabulary list (Independent Variable, Data, Hypothesis, Procedure, Constant), the matches are:

• First sentence: Independent Variable
• Second sentence: Data
• Third sentence: Hypothesis
• Fourth sentence: Procedure
• Fifth sentence: Constant
