Science isn't just for people in white lab coats holding bubbling beakers. Honestly, it’s just a fancy way of saying "I have a question and I don't want to be wrong about the answer." Whether you’re trying to figure out why your sourdough starter died or why a billion-dollar rocket engine keeps exploding on the launchpad, you’re likely using some version of the six step scientific method. It's a framework. A guardrail. It keeps our monkey brains from seeing patterns that aren't there.
Most of us learned this in seventh grade and immediately forgot it. We think we "just know" things. But the world is messy. Our biases are loud. That’s where the formal process comes in to save us from ourselves. It’s less of a rigid checklist and more of a philosophy for finding the truth in a sea of noise.
1. Observation: The "Wait, What?" Moment
Everything starts here. You notice something. Maybe it’s weird, or maybe it’s just interesting. For example, Sir Alexander Fleming didn't set out to change medicine; he just noticed that some mold was killing the bacteria in his petri dish. That’s it. A simple observation.
In the modern world, this might look like a data scientist noticing a weird dip in user engagement every Tuesday at 3:00 PM. It’s the spark. Without a curious observation, the rest of the six step scientific method is just an academic exercise. You have to care enough to look closer. You’re basically a detective at this stage, gathering clues before you even have a suspect.
2. The Question: Narrowing It Down
Once you’ve seen something, you have to ask a specific question. "Why is the sky blue?" is a classic, but for science to work, it helps to be even more granular. If you’re a gardener, you might ask, "Does this specific brand of organic fertilizer actually make my tomatoes grow faster than the cheap stuff?"

Bad questions lead to bad science. If your question is too broad, like "How do plants grow?", you'll never finish your experiment. You need a target. A bullseye. This is where you define the scope. You’re setting the boundaries of your investigation. It’s the difference between wandering in the woods and following a trail map.
3. The Hypothesis: Making an Educated Guess
This is the part everyone gets hung up on. A hypothesis isn't just a random guess; it’s a "if/then" statement based on what you already know. It has to be testable. If you say, "My car won't start because ghosts are haunting the engine," that’s not a scientific hypothesis because you can't test for ghosts. At least, not yet.
A better one? "If I replace the car battery, then the engine will start because the current battery is five years old." See the difference? It’s grounded. It’s actionable. You’re essentially sticking your neck out and saying, "I think this is what's happening." And here's the kicker: it’s perfectly okay—even great—to be wrong.
Why Being Wrong is Actually a Win
In the real world of research, "failing" to prove your hypothesis is still progress. It’s one less wrong answer you have to worry about. Thomas Edison famously didn't fail 1,000 times; he just found 1,000 ways not to make a lightbulb. That mindset is the heartbeat of the six step scientific method.
4. The Experiment: Testing the Theory
Now we get to the fun stuff. Or the tedious stuff, depending on who you ask. The experiment is where you put your hypothesis through the ringer. You need variables. Specifically, an independent variable (the thing you change) and a dependent variable (the thing you measure).
If you’re testing the tomato fertilizer, the fertilizer is your independent variable. The height of the plants is your dependent variable. But you also need a "control group." These are the poor tomatoes that get no fertilizer at all. If you don't have a control, you won't know if your tomatoes grew because of the fertilizer or just because the sun was out.
- Variable 1: The Fertilizer (Independent)
- Variable 2: Plant Height (Dependent)
- The Control: Plain water only
You have to be disciplined here. If you change the fertilizer and the amount of water at the same time, you've ruined the whole thing. You won't know which one did the heavy lifting. Consistency is everything. One change at a time. That's the golden rule.
5. Data Analysis: What Does it All Mean?
The experiment is over. You have a notebook full of numbers, or a spreadsheet that looks like a nightmare. Now you have to make sense of it. This is where you look for trends. Did the fertilized tomatoes actually grow taller, or was the difference so small it could just be luck?
Scientists use statistics to figure this out. They look for "statistical significance." Basically, they're asking: "Is this result real, or did I just get lucky?" If your fertilized plants grew 0.5 inches more than the others, that might not mean much. If they grew six inches more, now you’re onto something.
Don't ignore the outliers. Sometimes the most interesting thing in your data is the one plant that died for no reason. Maybe there’s a second experiment hiding in that failure. Analyze everything. Be ruthless. Don't try to force the data to fit your hypothesis just because you want to be right. That's how bad science happens.
6. Drawing Conclusions and Sharing Results
Finally, you decide. Was your hypothesis right? If yes, awesome. If no, also awesome—now you know what not to do next time. But the six step scientific method doesn't end in your own head. You have to tell people.

In the professional world, this means peer review. You write up your findings and let other smart people try to poke holes in your logic. It’s a brutal process, but it’s why we can trust things like medicine and bridge designs. If your "truth" can't survive a few questions from colleagues, it probably wasn't the truth to begin with.
Even if you’re just doing this at home, talk about it. Share your results. "Hey, turns out the expensive fertilizer is a total scam." That’s the final step of the loop.
Putting the Method Into Practice
You don't need a lab to use this. Next time your Wi-Fi is acting up, don't just reset the router and hope for the best. Use the process.
- Observe: The internet is slow in the bedroom but fine in the kitchen.
- Question: Is the wall between the rooms blocking the signal?
- Hypothesis: If I move the router to the hallway, then the bedroom signal will improve.
- Experiment: Move the router. Run a speed test in both rooms.
- Analyze: The speed test shows 50Mbps in the bedroom now, up from 5Mbps.
- Conclude: The wall was definitely the problem. Tell your roommates to stop moving the router back.
The six step scientific method is really just a tool for clarity. It strips away the "I think" and "I feel" and replaces it with "I observed" and "I measured." In a world full of misinformation and "gut feelings," that’s a superpower.
Stop guessing. Start testing. The more you apply this logic to small daily problems, the better you’ll get at spotting the big lies. It's about being a little more certain in an uncertain world. Go find something to observe today. Test a theory. See what happens. It's literally how we built the modern world.
