Reviewing Scientific Method and Reading Graphs

John is heading outside to go to the park and notices that it is much warmer today. He also hears many more crickets chirping and wonders why that is.  What step of the scientific method is John using?

• Hypothesis

• Conclusion

• Question

• Research

John knows that he needs to make sure that his prediction is correct and starts thinking about a plan to show that. He designs a plan that will count the number of times that a cricket chirps each hour. He knows that he will need to count daily and also record the temperature for each day. He determines that recording the number of counts will be his best plan. He decides to do this for the next three weeks. Which step of the scientific method is John using?

• Analyze Data

• Collect Data

• Conclusion

• Design an Experiment

John spends time studying his results. He notices that on the days when the weather is warmer that there are significantly more cricket chirps. Which step of the scientific method is John using?

• Forming an Hypothesis

• Reaching a Conclusion

• Collecting Data
