Scientific method

What is a conclusion in the context of the scientific method?

• A detailed explanation of the experimental procedure.

• A summary of the results of an experiment and whether the hypothesis was supported.

• A list of all the materials used in the experiment.

• An introduction to the research question being studied.

What is an example of a variable that should be controlled in a plant growth experiment?

• The amount of sunlight each plant receives.

• The type of soil used for all plants.

• The number of plants in each group.

• The frequency of watering the plants.

What is the significance of repeating experiments in scientific research?

• To ensure reliability and accuracy of the results.

• To make the research process longer and more complicated.

• To confuse the researchers with varying outcomes.

• To reduce the cost of conducting experiments.

What is a good hypothesis for an experiment measuring leaf growth in different light conditions?

• If plants are placed in bright light, then they will grow more green leaves than in dim light.

• Plants will grow equally in both bright and dim light conditions.

• Dim light will promote faster leaf growth than bright light.

• Leaf growth is not affected by light conditions.

What is a variable in an experiment?

• Any factor that can be changed or controlled in an experiment.

• A fixed element that does not change during the experiment.

• The outcome that is measured in response to changes in the experiment.

• A type of equipment used to conduct the experiment.

What is the difference between qualitative and quantitative data?

• Qualitative data involves numerical measurements, while quantitative data describes characteristics or qualities.

• Qualitative data describes characteristics or qualities, while quantitative data involves numerical measurements.

• Qualitative data is always more reliable than quantitative data.

• Quantitative data is subjective, while qualitative data is objective.

What is a testable prediction in a scientific investigation called?

• Hypothesis

• Theory

• Assumption

• Conclusion

What does it mean to analyze data in the scientific method?

• To collect data without any interpretation.

• To interpret the results of an experiment to determine if the hypothesis is supported.

• To ignore the results and focus on the methodology.

• To present the data in a visual format without analysis.

What is the independent variable in an experiment testing how watering affects plant growth?

• The type of plant used in the experiment.

• The amount you water each plant.

• The size of the pots used for planting.

• The amount of sunlight the plants receive.

What is the importance of peer review in scientific research?

• To validate research findings and ensure accuracy before publication.

• To increase the number of publications by researchers.

• To provide funding for scientific projects.

• To allow researchers to bypass ethical standards.
