6th Grade Earth Space Final Practice

What is the correct order of the scientific method steps?

• Observation, Hypothesis, Experiment, Analysis, Conclusion

• Hypothesis, Observation, Experiment, Conclusion, Analysis

• Experiment, Observation, Hypothesis, Analysis, Conclusion

• Observation, Experiment, Hypothesis, Conclusion, Analysis

Why is it important to test a hypothesis?

• To prove the hypothesis is correct.

• To gather evidence that either supports or refutes the hypothesis.

• To make the experiment take longer.

• To confuse other scientists.

A constant variable in an experiment is:

• The variable that is changed by the scientist.

• The variable that is measured by the scientist.

• A variable that stays the same throughout the experiment.

• The group that does not receive the experimental treatment.

The independent variable in an experiment is:

• The variable that is changed by the scientist.

• The variable that is measured by the scientist.

• A variable that stays the same throughout the experiment.

• The group that does not receive the experimental treatment.

The dependent variable in an experiment is:

• The variable that is changed by the scientist.

• The variable that is measured by the scientist.

• A variable that stays the same throughout the experiment.

• The group that does not receive the experimental treatment.

What is the main difference between a control group and an experimental group?

• The control group receives the experimental treatment, while the experimental group does not.

• The experimental group receives the experimental treatment, while the control group does not.

• The control group is larger than the experimental group.

• There is no difference between the two groups.

A scientific theory is best described as:

• A guess about how something works.

• A well-tested and widely accepted explanation of a natural phenomenon.

• A statement that describes what always happens under certain conditions.

• An opinion held by a scientist.

A scientific law is best described as:

• A guess about how something works.

• A well-tested and widely accepted explanation of a natural phenomenon.

• A statement that describes what always happens under certain conditions.

• An opinion held by a scientist.

How are scientific theories and laws different?

• Theories are always proven to be true, while laws are not.

• Laws explain why something happens, while theories describe what happens.

• Theories explain why something happens, while laws describe what happens.

• Theories are less reliable than laws.

Why is peer review important in science?

• It helps scientists get famous.

• It ensures that scientific work is evaluated by other experts for accuracy and validity.

• It makes scientific papers longer and more complicated.

• It guarantees that all published research is correct.
