Unit 1 Scientific Inquiry Exam Review

What do you do to test a hypothesis?

• Ask a question
• Conduct an experiment
• Enter data into a spreadsheet

Suppose you conduct an investigation to find out the types of soil in your neighborhood. Why would it be helpful to test the soil at 10 different locations instead of just a single location? 

• To ensure that your observations are complete and representative of the entire area
• To provide extra data in case you lose some of it
• To satisfy the requirement that experiments have a minimum of 10 data points

In what order are the steps of the scientific method usually completed? 

• Form a Hypothesis, Define the problem, Perform Experiments, Organize and Analyze Data, Draw Conclusions, Communicate Results.
• Define the problem, Form a Hypothesis, Organize and Analyze Data, Perform Experiments, Draw Conclusions, Communicate Results.
• Define the problem, Form a Hypothesis, Perform Experiments, Organize and Analyze Data, Draw Conclusions, Communicate Results

Which of the following is an example of qualitative data?

• Each mouse in the study lived for 3 years.

• Each mouse in the study was 75 cm long.

• Each mouse in the study has brown ears.

• Each mouse in the study ate four times a day.

Which of the following is an example of quantitative data? 

• Each rat in the study has brown and white spots.
• Each rat in the study has a tail that is 25 cm long.
• Each rat in the study chose to eat organic food.
• Eat rat in the study chose to sleep close to other rats.

Why is data important to scientific endeavor? 

• Data is the information that supports or does not support a hypothesis.
• Data is the information that proves all hypotheses are correct.
• Data is the information that proves whether or not a scientist is biased.
• Data is necessary to form a hypothesis

• Data showing how the number of hours spent studying affects the score on an exam.

All graphs need a title. 

• True
• False

As the number of rabbits in a community goes up, the number of foxes in the same community goes up. This is an example of what type of relationship?

• direct
• indirect
• cyclic
• non-related

The number of spiders in the house and the outside air temperature have an indirect relationship. What will happen to the number of spiders in the house as the outside air temperature decreases? 

• decrease
• increase
• stay the same
• increase then decrease in a regular pattern
