Brian was flying to Orlando. When he took off in his hometown it was raining. Brian noticed the clouds were dark when the plane was taking off the ground. But, once the plane got above the cloud cover, he noticed the clouds were white. If Brian was to create an experiment about this observation, what would be the first step he would follow of the scientific method(inquiry)?

• Form a question

• Create an experiment

• Analyze data

• Create a conclusion

After a hypothesis is formed, what would be the next step in the scientific method (inquiry)?

• Ask a question

• Analyze data

• Form a conclusion

• Design and conduct experiment

The factor that changes as a result of the changes to the manipulated variable in an experiment is the:

What is a hypothesis?

• an observation

• a possible answer to a question

• a problem to be solved

• an accurate measurement
