The scientific method is a framework we can use to understand our universe. There are many variations of the process, but generally speaking it goes something like this:
- Step 1: Observe and ask a question
We begin by noticing something in everyday life. For example, you might observe that your plants seem to grow faster when you sing while watering them. This leads to a clear, observable question: "Does singing to plants make them grow faster?."
- Step 2: Conduct research
Next we have to review existing knowledge. A quick look at reliable sources (like biology textbooks or scientific articles) reveals that plants might respond to vibrations, Carbon Dioxide from breath, or sound waves. This helps avoid reinventing the wheel and refines your approach.
- Step 3: Form a hypothesis
Based on observations and research, we propose a testable explanation: "If plants are exposed to daily singing, then they will grow faster than plants not exposed to singing, because the sound vibrations stimulates growth."
- Step 4: Make a prediction
We can derive specific, falsifiable predictions from the hypothesis. For example, we could predict that "Sung-to plants will grow at least 20% taller compared to control plants, over a 4 week period."
- Step 5: Test the hypothesis
For the controlled experiment, you buy 10 identical seedlings and divide them into two groups of five. Group A will be subject to your singing, while Group B (the control group), won't be sung to. Be sure to keep everything else the same: same soil, pots, water, temperature, and location. This controls variables.
- Step 6: Analyse the data and draw conclusions
You look at the data and notice Group A was on average 10% taller than the plants in Group B by the end of the experiment. This partially supports the hypothesis, but the difference might be due to chance or other factors like uneven watering, or light pollution. You conclude that singing may have a small effect on growth, but more tests are needed to rule out biases.
- Step 7: Publish results and iterate
We can share our findings in a blog post or journal article. Then use your results to refine the hypothesis. For example: "Plants may respond differently to sound vibrations depending on the time of day, due to their circadian rhythms regulating processes like photosynthesis and recovery." This can be tested by comparing sound exposure in the daytime vs nighttime.
So, that's how the scientific method turns curiosity into reliable knowledge.
