6th Grade Science Challenge

What is the first step in the scientific method?

• Form a hypothesis immediately

• Ask a question or identify a problem

• Analyze data before asking questions

• Conduct an experiment

Explain the difference between an independent variable and a dependent variable.

• The dependent variable is controlled, and the independent variable is observed.

• The independent variable is manipulated, and the dependent variable is measured.

• The independent variable is the outcome, and the dependent variable is the cause.

• The dependent variable is manipulated, and the independent variable is measured.

Why is it important to have a control group in an experiment?

• To make the experiment more expensive

• To confuse the results

• To increase the sample size

• To provide a baseline for comparison and isolate the effect of the independent variable.

What is the purpose of a hypothesis in scientific inquiry?

• A hypothesis is used to prove a theory correct

• A hypothesis is a fact that has been proven in science

• The purpose of a hypothesis in scientific inquiry is to provide a testable explanation for a phenomenon or a proposed solution to a problem.

• A hypothesis is unnecessary in scientific inquiry

Describe the process of peer review in scientific research.

• Peer review involves submitting research papers to social media influencers for evaluation.

• Peer review is a process where researchers review their own work before publication.

• Peer review in scientific research is a method of randomly selecting papers for publication.

• Peer review in scientific research involves submitting a research paper to a group of experts in the same field for evaluation. These experts assess the quality, validity, and significance of the research before it can be published. The process helps ensure the credibility and accuracy of scientific findings.

How can you ensure that an experiment is fair and unbiased?

• Always use the same group for all experiments

• Use only male participants for the experiment

• Allow participants to choose their group

• Randomize the assignment of subjects to groups, use control groups, blind participants and researchers, and minimize confounding variables.

What are the different types of variables in an experiment?

• Uncontrolled variables

• Experimental variables

• Random variables

• Independent variables, dependent variables, and controlled variables.

Why is it important to collect and analyze data in scientific investigations?

• It confuses the results and leads to wrong conclusions.

• It helps in drawing accurate conclusions and making informed decisions.

• It is a waste of time and resources.

• Data analysis is not necessary in scientific investigations.

Explain the concept of replication in scientific experiments.

• Replication in scientific experiments involves altering the variables to see different outcomes.

• Replication in scientific experiments is unnecessary and adds no value to the results.

• Replication in scientific experiments is the process of creating exact duplicates of the original experiment.

• Replication in scientific experiments is the process of repeating the experiment multiple times to ensure the results are consistent and reliable.

What is the role of a control variable in an experiment?

• A control variable is used to manipulate the dependent variable in an experiment.

• The role of a control variable in an experiment is to maintain consistency and isolate the effects of the independent variable.

• The control variable is the variable that changes in response to the independent variable.

• The role of a control variable is to introduce bias into the experiment.
