Scientific Method Worksheet – Solved and Explained

---

#### Part 1: Put the following steps of the scientific method in the proper order.

The correct order of the scientific method is:

1. Identify the problem
2. Research the problem
3. Make a hypothesis
4. Test the hypothesis
5. Observe and record
6. Arrive at a conclusion

✔ Final Answer (with numbers):
- 1 – Identify the problem
- 2 – Research the problem
- 3 – Make a hypothesis
- 4 – Test the hypothesis
- 5 – Observe and record
- 6 – Arrive at a conclusion

🔍 Explanation of the Scientific Method Steps:

1. Identify the problem: This is the first step where you ask a question or notice something that needs to be investigated.
2. Research the problem: Gather background information and existing knowledge about the topic.
3. Make a hypothesis: Form an educated guess about what will happen based on your research.
4. Test the hypothesis: Conduct an experiment to test your prediction.
5. Observe and record: Collect data by making observations and recording measurements during the experiment.
6. Arrive at a conclusion: Analyze the results and determine whether they support or reject the hypothesis.

> ⚠️ Note: The scientific method is often cyclical—after a conclusion, new questions may arise, leading to further investigation.

#### Part 2: Match the following terms with the correct definition.

Let’s match each term to its correct definition:

| Number | Term | Definition Letter | Explanation |
|--------|--------------------|-------------------|-------------|
| 1 | Hypothesis | B | A hypothesis is an educated guess about the solution to a problem. It's a testable prediction. |
| 2 | Control | E | A control group is used to show that the result of an experiment is really due to the condition being tested, not other factors. |
| 3 | Dependent Variable | G | This is the outcome or response that is measured in an experiment. It *depends* on the independent variable. |
| 4 | Experiment | A | An experiment is an organized process designed to test a hypothesis under controlled conditions. |
| 5 | Conclusion | D | A conclusion is a judgment based on the results of an experiment. It answers whether the hypothesis was supported. |
| 6 | Data | C | Data refers to observations and measurements recorded during an experiment. |
| 7 | Independent Variable | F | This is the factor that is deliberately changed or manipulated during the experiment. |

✔ Final Answers:
1. B
2. E
3. G
4. A
5. D
6. C
7. F

✔ Summary of Matching:

- Hypothesis → B: Educated guess
- Control → E: Shows cause-effect by comparison
- Dependent Variable → G: What you measure
- Experiment → A: Organized test
- Conclusion → D: Judgment from results
- Data → C: Observations & measurements
- Independent Variable → F: What you change

🧪 Visual Context:

The two illustrations depict scientists conducting experiments—using lab equipment like beakers, test tubes, and Bunsen burners. These visuals reinforce the idea of hands-on testing and observation, which are key parts of the scientific method.
