The Scientific Method: 7 Steps from Observation to Conclusion

the scientific method

1. Observation:

Observation is noticing or perceiving aspects of nature.

2. Recognition of the problem: Once the facts have been established, it is necessary to contrast them and recognize problems.

3. Hypothesis

The hypothesis is a tentative explanation for an observation. A hypothesis must be capable of being tested by experiment.

4. predictions

Predictions are the expected consequences of hypotheses.

5. Experimentation

An experiment is a test or trial under controlled conditions to investigate the validity of a hypothesis.

6. Analysis of results: The data obtained through experimentation need to be analyzed in the light of the proposed hypotheses and predictions.

7. conclusion An important step in the scientific method is the communication of our results, it is a way of sharing and announcing to the world what we have obtained and how we have obtained it

You turn on a light switch and the bulb doesn't come on.

Note: The bulb did not light up.

Question: Is the bulb burned out?

Hypothesis : The bulb is burned out.

Prediction: If I replace the bulb and it turns on, then my hypothesis is validated. If the bulb doesn't light up, my hypothesis is invalid.

Experiment: Replace the light bulb.

Result: the new bulb lights up.

Conclusion: My hypothesis is validated. the bulb was burned out
