Scientific Investigation SOL Review Quiz

During a science fair, Scarlett proposes that plants grow faster under blue light than under red light. What is this proposal called in scientific investigation?

• A conclusion based on data collected

• A guess with no basis in observation or theory

• A proposed explanation based on limited evidence as a starting point for further investigation

• A detailed report of experimental results

During a school science fair, Anika investigates the effect of sunlight on plant growth. What does drawing a conclusion in this investigation involve?

• Deciding on the next type of plant to test

• Repeating the experiment with the same plant until it grows as expected

• Evaluating the data and deciding whether it supports or refutes the hypothesis that sunlight affects plant growth

• Publishing the results in the school newsletter without peer review

Why is peer review an important part of the scientific process?

• It allows scientists to share their results with the public

• It ensures that the research is original, significant, and rigorous

• It helps in formulating the hypothesis

• It is the final step in drawing conclusions

During an experiment on plant growth, Daniel notices that the data does NOT support his hypothesis that sunlight increases growth speed. What should Daniel do?

• Ignore the data

• Change the data to fit the hypothesis

• Re-evaluate the hypothesis and possibly revise or formulate a new one
