Scientific Investigation Quiz Interactive Science 7.2

What is the first step in a scientific investigation according to the text?

• Conducting an experiment

• Making a prediction

• Observing and collecting data

• Sharing findings with other scientists

Which of the following is NOT listed as a type of investigation other than controlled experiments?

• Models

• Surveys

• Sampling

• Observational studies

According to the text, why is it important for scientists to share their findings?

• To manipulate variables more effectively

• To confirm their hypotheses independently

• To allow other scientists to disagree or confirm the findings

• To design better experiments

What is the primary purpose of using models in science according to the text?

• To make experiments more difficult

• To represent other things and test designs

• To create physical objects

• To replace real experiments

Why might scientists prefer using computer-generated models over real cars for some experiments?

• They are less expensive to build

• They can control experiment conditions more easily

• They are more fun to use

• They can be driven

According to the text, what is a limitation of using models in science?

• They can provide different results from real objects

• They are always accurate

• They are easier to use than real objects

• They can replace real objects completely

What is the primary purpose of using surveys and sampling in scientific investigations?

• To create detailed reports for publication

• To collect data by examining a subset of individuals

• To entertain scientific communities

• To test new laboratory equipment

Why might doctors at a picnic want to know what each person ate and drank?

• To decide what food to bring next time

• To make a schedule for future picnics

• To find the source of any illness that occurred

• To survey food preferences for statistical analysis

How can doctors generalize their results from a picnic survey?

• By interviewing every single participant at the picnic

• By examining only the healthy individuals

• By applying findings to all people at the picnic

• By changing the food served at the picnic

What is the purpose of using scientific methods in investigations?

• To create complex experiments only

• To find answers to specific questions and solve problems

• To follow a strict set of rules without flexibility

• To make experiments longer
