What are the steps of the scientific method?

• Observation, Question, Analysis, and Conclusion

• Question, Hypothesis, Experiment, and Conclusion.

• Observation, Question, Hypothesis, Experiment.

• Observation, Question, Research, Hypothesis, Experiment, Analysis, and Conclusion

Answer explanation

Great! Remember, the scientific method is a process rather than out-of-order steps.

"It ends and begins again with ........"

Answer explanation

Remember, The entire scientific process leads us to new information. When shared, they can be used in future studies.

Which of the following is an example of a well-defined question?

• "Why is the sky blue?"

• "How does the amount of sunlight affect plant growth?"

• "what is the meaning of life?"

• "Is the earth flat?"

Answer explanation

Remember, The details we notice during observation will spark our curiosity. The most interesting ones will make us ask questions that we want answered.

When experimenting, why is it important to formulate a testable hypothesis?

• To guide the experiment and draw valid conclusions.

• To make the experiment more challenging.

• To ensure the experiment is successful.

• To make the experiment more reliable.

Answer explanation

Remember, hypotheses are the tentative explanation to our initial question based on what we know so far.

What is an independent variable?

• The variable or thing that will change in our experiment.

• The variable or thing we are testing. We will be collecting data.

• The variable or thing that we are testing. We will be collecting data.

• Any factor that can be changed or controlled.

• Any factor that

Answer explanation

Remember, The dependent variable is the response that is measured. One way to think about it is that the dependent variable depends on the change in the independent variable.

How do you correctly write a hypothesis?

• If (independent variable) the, (dependent variable)

• If ( dependent variable) then, (dependent variable)

• If ( Independent variable) then, (Independent variable)

• If ( dependent variable) the, (dependent variable)

Answer explanation

What is a testable hypothesis?

• A guess based on personal feelings.

• An idea that can be tested through experimentation.

• A statement that cannot be proven or disproven.

• A belief without any evidence.

Answer explanation

Remember, The scientific method's purpose is to make hypotheses that are tested through experiments.
