scientists use the scientific method to investigate questions and phenomena. as part of that process, a question is asked, and research is performed on the topic. a hypothesis is then formulated using an if - then statement. to develop a well - constructed hypothesis, a scientist will need to identify the □ variable, which is the one factor that will be changed. the part of the experiment that will be measured is called the □ variable. observations and measurements will be collected during the investigation, which is called □. data will later be analyzed to draw a □ and communicate findings to the scientific community. the conclusion states if the hypothesis was supported or refuted (not supported).

Accepted Answer

# Brief Explanations:
1. The first blank: In an experiment, the variable that is changed by the scientist is the independent variable. So we choose "independent".
2. The second blank: The variable that is measured and depends on the independent variable is the dependent variable. So we choose "dependent".
3. The third blank: The process of collecting observations and measurements during an investigation is called an experiment? No, wait, the observations and measurements are data? Wait, no, the activity of collecting is part of the experiment? Wait, no, the text says "Observations and measurements will be collected during the investigation, which is called...". Wait, the investigation here is the experiment? No, the options have "experiment" and "data" and "investigation". Wait, the correct term for the part where you collect observations and measurements is the experiment? Wait, no, the data is what you collect. Wait, no, the sentence is "Observations and measurements will be collected during the investigation, which is called [blank]". Wait, the investigation here is the experiment? Wait, the options: "experiment" is one. Wait, no, let's re - read. The scientific method steps: after hypothesis, you do an experiment (the investigation) where you change the independent variable, measure the dependent variable, collect data (observations and measurements). Wait, the first blank: "the one factor that will be changed" is independent variable. Second blank: "the part of the experiment that will be measured" is dependent variable. Third blank: "Observations and measurements will be collected during the investigation, which is called [experiment]"? No, the investigation is the experiment. Wait, no, the data is the observations and measurements. Wait, the options: "data" is an option. Wait, the sentence: "Observations and measurements will be collected during the investigation, which is called [data]"? No, data is what is collected. Wait, maybe I made a mistake. Let's go step by step.

First blank: "the one factor that will be changed" → independent variable (because independent variable is the one we manipulate). So first blank: independent.

Second blank: "the part of the experiment that will be measured" → dependent variable (because it depends on the independent variable). So second blank: dependent.

Third blank: "Observations and measurements will be collected during the investigation, which is called [experiment]"? No, the investigation is the experiment. Wait, the options have "experiment" as an option. Wait, no, the data is the observations and measurements. Wait, the sentence is "Observations and measurements will be collected during the investigation, which is called [data]"? No, data is the result of the collection. Wait, maybe the third blank is "experiment"? No, the investigation is the experiment. Wait, let's check the last blank: "Data will later be analyzed to draw a [conclusion] and communicate findings...". Yes, after analyzing data, you draw a conclusion. So last blank: conclusion.

So let's re - order:

1. First blank: independent (the variable changed)
2. Second blank: dependent (the variable measured)
3. Third blank: experiment? No, wait, the "investigation" is the experiment. Wait, the options have "experiment" and "investigation". Wait, the text says "research is performed on the topic... a scientist will need to identify the [independent] variable... The part of the experiment that will be measured is called the [dependent] variable. Observations and measurements will be collected during the investigation, which is called [experiment]? No, the investigation is the experiment. Wait, maybe the third blank is "data"? No, data is what is collected. Wait, I think I messed up. Let's use the options:

Options: hypothesis, dependent, investigation, data, experiment, conclusion, independent, reasons.

First blank: "the one factor that will be changed" → independent (so independent variable)

Second blank: "the part of the experiment that will be measured" → dependent (dependent variable)

Third blank: "Observations and measurements will be collected during the investigation, which is called [experiment]"? No, the investigation is the experiment. Wait, the "investigation" here is the experiment. Wait, the options have "experiment" as a separate option. Wait, maybe the third blank is "experiment"? No, the investigation is the experiment. Wait, the sentence is "Observations and measurements will be collected during the investigation, which is called [data]"? No, data is the observations and measurements. So the third blank should be "experiment"? No, I think the correct answers are:

1. independent
2. dependent
3. experiment? No, wait, the fourth blank: "Data will later be analyzed to draw a [conclusion]". Yes, conclusion is what you draw after analyzing data. So:

First blank: independent

Second blank: dependent

Third blank: experiment? No, the "investigation" is the experiment. Wait, the options have "investigation" as an option. Wait, the text says "research is performed on the topic... a hypothesis is formulated... a scientist will need to identify the [independent] variable... The part of the experiment that will be measured is called the [dependent] variable. Observations and measurements will be collected during the investigation, which is called [experiment]? No, I think the correct sequence is:

1. independent (variable changed)

2. dependent (variable measured)

3. experiment (the investigation where you collect data)

4. conclusion (drawn from data analysis)

Wait, let's check the options again. The blanks are:

1. [blank] variable (changed) → independent

2. [blank] variable (measured) → dependent

3. [blank] (where observations and measurements are collected) → experiment

4. [blank] (drawn from data analysis) → conclusion

Yes, that makes sense. So:

First blank: independent

Second blank: dependent

Third blank: experiment

Fourth blank: conclusion

Wait, but the third blank in the text: "Observations and measurements will be collected during the investigation, which is called [blank]". So the investigation is the experiment. So the third blank is "experiment".

# Answer:
1. independent
2. dependent
3. experiment
4. conclusion
