Review Quiz 2: Nature of Science

Why is it important for scientific investigations to be replicable?

• To ensure that the results are unique and cannot be duplicated.

• To allow other scientists to verify and validate the findings.

• To make the experiments more complex.

• To increase the cost and resources needed for science.

What would likely happen if different groups conducting the same scientific investigation do not have replicable methods?

• Their results will be more reliable.

• They might reach different conclusions, affecting the validity of the results.

• The cost of the investigation will decrease.

• The investigation will take less time to complete.

Imagine two groups are conducting the same investigation on plant growth under different types of light. What aspect of their methodology should be identical to ensure replicability?

• The color of the pots used for planting.

• The type of plants used in each group.

• The time of day when they water the plants.

• The background music played in the lab.

What role does peer review play in the context of replicable scientific investigations?

• It decreases the credibility of the results.

• It ensures that experiments are more complex.

• It helps verify the accuracy and reliability of the results.

• It makes the scientific method less important.

Design a simple experiment to test the effect of sunlight on plant growth. What would be a critical component to include to ensure that other researchers can replicate your study?

• A detailed description of the plant species and care conditions.

• An expensive set of gardening tools.

• A unique type of soil found only in specific locations.

• Randomly chosen plant pots.

If a scientific investigation's results are not replicable, what is the most likely impact on the scientific community?

• Increased collaboration among scientists.

• Decreased trust in the findings of the investigation.

• More funding for the specific area of research.

• Faster dissemination of results.

Consider an investigation where different groups observed different results under supposedly identical conditions. What should be the next step to understand these discrepancies?

• Ignore the differences and publish the most favorable results.

• Re-examine and standardize the methodologies used by each group.

• Increase the number of subjects in the experiment.

• Change the hypothesis to fit the most common results.

Why is it important for the methods section of a scientific report to be detailed and precise?

• To make the report longer and more comprehensive.

• To ensure that other researchers can replicate the study exactly.

• To use more technical jargon and complex language.

• To make the findings seem more impressive.
