Let's solve this step-by-step by matching each statement to the correct Scientific Method step: O (Observation), H (Hypothesis), E (Experiment), or C (Conclusion).

We’ll go through each numbered statement and determine which scientific method step it describes.

---

Definitions of Each Step:

- O - Observation: Using senses to gather information about an event or object. It’s the initial step where you notice something.
- H - Hypothesis: A testable prediction or educated guess based on observations.
- E - Experiment: A controlled procedure designed to test a hypothesis.
- C - Conclusion: The interpretation of results from the experiment; determining whether the hypothesis is supported.

Now, let’s match each statement:

1. A question turned into a statement.
→ This is forming a hypothesis (a statement that answers the question).
✔ H

2. Analysis of the data and the collected information
→ This happens after the experiment — analyzing results leads to a conclusion.
✔ C

3. Can be reproduced by others.
→ Refers to reproducibility of experiments — part of a good experiment.
✔ E

4. Carefully designed and controlled.
→ Describes how an experiment should be set up.
✔ E

5. If hypothesis is proven, the original question is answered.
→ This is part of the conclusion, where you determine if your hypothesis was correct.
✔ C

6. If not proven, a new hypothesis is made.
→ After a failed test, you revise your hypothesis.
✔ H

7. Includes explanations for the observations.
→ Explaining why things happened — this is part of the conclusion.
✔ C

8. It is able to be tested by others.
→ A good hypothesis must be testable.
✔ H

9. It is used to test the hypothesis.
→ The experiment is what tests the hypothesis.
✔ E

10. Others will be able to repeat the experiment.
→ Reproducibility is a key feature of a well-designed experiment.
✔ E

11. Seeing, hearing, feeling, smelling and tasting
→ These are the five senses used in observation.
✔ O

12. Statement about the event or object to be researched.
→ This is a hypothesis — a proposed explanation.
✔ H

13. Tests a single variable.
→ Controlled experiments test one variable at a time.
✔ E

14. The question being researched.
→ This comes before the hypothesis — often based on observation. But the question itself isn't a step, but the starting point. However, the process begins with observation, which leads to a question. But here, since it's "the question", it's closely tied to observation as the source.
But actually, the question arises from observation. So this is still O.
✔ O

15. This is based on collected information.
→ The conclusion is based on data collected during the experiment.
✔ C

16. Used to learn about or identify an event or object.
→ This is the purpose of observation.
✔ O

17. Using one or more of the five senses
→ Again, this is observation.
✔ O

18. Will answer: Is the guess true or false?
→ The experiment determines if the hypothesis (guess) is true or false.
✔ E

19. Will prove or disprove the hypothesis.
→ This is the result of the experiment.
✔ E

20. Will usually result in the same or new outcomes.
→ Experiments can be repeated with consistent or new results — this refers to experiment reproducibility.
✔ E
