SC.5.N.1.1 Scientific Investigation

What is the role of variables in an experiment?

• Variables are factors that can change in an experiment.

• Variables are constants that remain unchanged throughout the experiment.

• Variables are the final results of the experiment.

• Variables are the tools used to conduct the experiment.

What is a conclusion in scientific investigation?

• A conclusion is a summary of the results of an experiment, explaining whether the hypothesis was supported or not.

• A conclusion is the initial hypothesis proposed before conducting an experiment.

• A conclusion is a detailed report of all the materials used in the experiment.

• A conclusion is a list of questions that arise after the experiment.

What is a control group in an experiment?

• A group that receives the experimental treatment.

• A group that is not exposed to the experimental treatment and serves as a standard for comparison.

• A group that is used to manipulate variables in the experiment.

• A group that is randomly selected from the population.

What is an observation?

• An observation is the act of noticing and describing events or processes in a careful, orderly way.

• An observation is a random guess about an event or process.

• An observation is a conclusion drawn without evidence.

• An observation is a method of predicting future events.

What is data collection in scientific investigation?

• Data collection is the process of gathering information during an experiment to analyze and draw conclusions.

• Data collection is the method of recording observations without any analysis.

• Data collection is the act of summarizing results after an experiment is completed.

• Data collection is the process of formulating hypotheses before conducting an experiment.

What is a hypothesis?

• A proposed explanation for a phenomenon, which can be tested through experimentation.

• A definitive conclusion based on extensive research.

• An assumption made without evidence.

• A random guess about an outcome.

What is the purpose of a scientific experiment?

• To prove a theory without testing it.

• To test a hypothesis by manipulating variables and observing the outcomes.

• To collect data without any specific goal.

• To conduct research without any experimentation.

Why is it important to take notes during observations?

• Taking notes helps to accurately record observations, which can be used for analysis and reporting later.

• Taking notes is a requirement for passing the course.

• Taking notes allows you to avoid paying attention during the observation.

• Taking notes is only necessary for scientific experiments.

What is the difference between independent and dependent variables?

• The independent variable is the one that is measured or observed, while the dependent variable is the one that is changed or controlled in an experiment.

• The independent variable is the one that is changed or controlled in an experiment, while the dependent variable is the one that is measured or observed.

• The independent variable is always a constant, while the dependent variable can vary.

• The independent variable is the one that influences the dependent variable, but they are both measured in the same way.

Why is it important to repeat experiments?

• To verify results and ensure that findings are consistent and reliable.

• To make the experiment more complicated and difficult.

• To reduce the time taken for the experiment.

• To increase the number of variables involved in the experiment.
