You turn a light switch, and the bulb does not light.
- Observation: Light bulb did not light.
- Question: Is the light bulb blown?
- Hypothesis: The light bulb is blown.
- Prediction: If I replace the bulb and it lights, then my hypothesis is validated. If the bulb does not light, then my hypothesis is invalidated.
- Experiment: Replace the bulb.
- Result: New bulb lights up.
- Conclusion: My hypothesis is validated. The bulb was blown.

In what ways do we use scientific method in everyday life? Share examples.
The scientific method is as follows:
Create or discover relationships between things observed.
Confirm that the relationships and observations are repeatable.
Formalize your creations or discoveries into a language.
Communicate/share what you know with others through your language as accepted by others.
Knowledge is scientifically proven if others can use the language to duplicate your communication as knowledge of their own. From that perspective such knowledge becomes a discovery for whoever learns it, and it is very similar in feeling to any knowledge gained through discovery.
This scientific method is a common method employed by anything that uses a language; everyday examples are abundant. What’s rare is when the process reveals deep and complex relationships in a simplified form of language such that others can understand in a few seconds what took years of observation and experiment to discover or make. But the question asked for everyday examples of the scientific method, so here are a few examples.
Example 1: Someone points to a sign (in the classic sense of a sign) and says, “There!” And you look, and you behold, “Yes! There it is!”
Example 2: You are in a grocery store looking for mangos but you don’t see any mangos; yet because you read a sign somewhere, you believe that mangos are in the store. So, you ask someone if there are mangos in the store. They tell you “Produce, Isle 42.” You go to “Produce, Isle 42” and there is where you find/discover mangos!
Example 3: A crow calls out; others pay attention and acknowledge what and why.
Example 4: A bee dances and others discover flowers or honey.
Example 5: You buy a can that reads “pineapple chunks.” Later, you open the can and discover pineapple chunks!
Example 6: Watts equals volts times amps. Yeah, Baby! Thank you!
Example 7 (seven over-steps the boundaries of science): Death doesn’t require suffering and neither does life. So, what are we doing here?
Example 8 (also out on an edge somewhere that one knows): Suddenly, as if by magic, you exist.

I can’t find my keys.
Question at issue: Where the hell are my keys?
Hypothesis: I think my keys are in the car.
Test: I look in the car. I don’t see them.
Result: The chance that they are in the car and somehow I still didn’t see them is estimated at around 10% historically. The result is insignificant, so the experiment is inconclusive.
Replication: Ask my wife to look in the car. She doesn’t see them either.
Result: Now the probability that this result was due to chance has dropped to 1%, and it’s significant. Conclusion: Null hypothesis.The keys are not in the car.
Hypothesis: I think my keys are in the pants I wore last night.
Test: Find the pants. Can’t find the pants.
Result: Inconclusive. No evidence in favor, no evidence against.
Hypothesis: My son yells “your keys are wherever you left them!”
Falsifiability Check: This is not a scientific hypothesis, because it is not falsifiable — it can not be determined by examining the evidence. Also not helpful.
Hypothesis: My daughter thinks she saw my keys by the toaster.
Test: My daughter yells “Found your keys, Dad!”
Result: The keys in her hand constitute proof of her hypothesis.
Peer review: My wife says “She’s got your keys!” I run down, see them, and say thank you.
Conclusion: The keys were by the toaster.
Now I’m late.
Question at issue: At 8: 30 is it quicker to take the interstate or surface streets?
I take it you mean observe, create hypothesis, test hypothesis. The scientific method is all around us, even if it goes unrecognized. The three year old who notes that when he or she flips the light switch, the bulb lights up. Flip it down and it goes off. Repeat several times, and create a hypothesis that switches control light. Find another switch and flip it. Hypothesis confirmed!
Broadly speaking we use science in two ways- 1st- the material things that are made up by using science. They make our life easy and comfortable. AC, Car, fridge, kitchen appliances, utensils, tv, wifi, car etc. Even the house in which we live, are made up by using scientific (architectural) methods.
2nd- the non material or philosophical use of science. For example in Decision making we also use scientific methods. The five components of scientific method- problem, hypothesis, experimenting, observation and conclusion (PHEOC) are very handy in good decision making. Suppose you ate going through a dilemma, should you replace your old car?. You have identified the problem. Now you will collect informations regarding prose and cons of new car and about trendy cars and features as per you requirements. You are at second step- hypothesis. Now you go to various Showrooms to take test drives of many cars(experimenting). Next comes observation this can be static(from your past experience) or current(during the process of 1st to 3rd step PHE). After that you will find a conclusion should you buy a car, if yes, which one?
Scientific methods can be applied in behavioural management, anger management, study, conversation, daily chores etc. There are things which can be done normally, but if you do them scientifically you will be able to save your time, energy, money etc.

Troubleshooting. I love to fix things when they break, rather than simply replace them or call a repairman. And the method I use not only looks like the scientific method, it is the scientific method:
- Observe. What is working still, and what is not? Are there unexpected sounds, smells or behaviours? If possible, open up the device or chassis and poke around.
- Hypothesize. Have a look at the schematic, focusing on the portions that contribute to the behaviour that is faulty. Think about what combination of component failures might explain things. Often you can get a head start on this by searching Google with the device’s name, model number and symptoms. But usually Google will provide more than one hypothesis, so you still need to…
- Test. Whether you have one hypothesis or a dozen, you still don’t know what is wrong, so you need to come up with a way to test each one. The test may involve replacing a component, or using the device in a different way. Or it may be looking for other observations you missed in step 1, which may eliminate some hypotheses.
- Eliminate. If you had multiple hypotheses, you need to keep testing until you find the solution. Perhaps you will eliminate all of them, in which case you’ll have to go back to steps 1 and 2 to find a new possible cause.
Once you are done troubleshooting, you simply fix the one remaining hypothesis.
This process is very intense, and you need strong powers of observation, creativity and logic — just like other applications of the scientific method.
My apartment has thin walls and my cat kept waking me up at night with meows so loud that it would wake up the neighbours. (Usually, all he was looking for was love and affection, which I can understand, to a point. I am perfectly willing to hold him like a baby and nuzzle him, but at 4am?!)
These loud meows had been particularly effective at influencing my behaviour because I would respond out of fear that the two of us would annoy the neighbours and generate a complaint. I developed the hypothesis that he was using that particular meow because it worked and I was enabling him be responding consistently. I decided I could no longer encourage this behaviour so I decided to never acknowledge this type of meow again.
In the coming days, I stuck with my plan to ignore the ultra loud meows (and be proactive in meeting all his needs when I wasn’t asleep). Eventually, I noticed he was beginning to use all kinds of different meows (to continue to disrupt my desperately needed sleep). I was so impressed by his creativity and the sheer diversity of them that I decided catalogue them and analyze them just like a scientist might. (By now, you are probably realizing that I have an unhealthy affinity for cats) After I counted at least 30 meows, I began to realize that my cat had a “method” to his madness. He would try out a given meow. He would then gauge its efficacy. If it motivated me to respond a bit he would use it again. If not, he would discard it or modify it slightly and then test again. The diversity of meows being employed was a result of his experimentation to discover utterances that would be effective. I realized that my cat was using the scientific method on me to manipulate the behaviour of his test subject!
I’m sure he has no idea what the scientific method is. I don’t know how much of what he was doing was conscious. But the end result was a series of meows that were precisely tuned to manipulate my emotions and incite a given behaviour. In fact, they were refined to trigger a variety of different emotions: frustration/exasperation, fear, pity, compassion, love and the feeling that his meow was so utterly an unbearably cute that I could not ignore him.
This story is intended to be a bit silly, but it is 100% true. It is estimated that there are 600 million (small) cats in the world. I suspect that at least a part of their dominance on this planet can be attributed to their use of the scientific method to manipulate humans and to get us to feed them and do their bidding.
I don’t think it will be a scientific method but it is a technical and useful method if you are from a middle class family.
When we fry a puri or anything then we don’t fry it all the time. Indstead we switch off the gas after some minutes and we still have enough energy make the required dish. This scientific approach helps many to save energy and cost.

We use science in our day to day lives. Even from brushing in the morning to sleeping in the bed you need science to make it all comfortable for a person. The aesthetics the designs the different ideas inventions gadgets all make up to create our day to day lives more easy and flexible.
apply the 6 scientific method about everyday life?
The first idea to consider is what the American psychologist George Kelly, in the 1950s, called a “Personal Scientist”, in relation to his Personal Construct Theory – browse this last phrase for more info.
Most people nowadays are, to some degree, personal scientists.
Second, consider what happens when people do not use something resembling the scientific method in everyday life – e.g. followers of conspiracy theories, or astrology (even though in some aspects of their lives, the majority will still act as personal scientists).
Kelly believed that:
“anticipation and prediction are the main drivers of our mind. “Every man is, in his own particular way, a scientist”: i.e. people are constantly building up and refining theories and models about how the world works so that they can anticipate future events.”
Let’s look at a simplified of the scientific method:
From this you can see that in everyday life we often employ some of the steps shown in the diagram – for example:
- We might hypothesise about a question of interest, e.g. will a cold compress help reduce the inflammation of a heat rash in hot weather – and then we try it in order to test the hypothesis and maybe reach a conclusion.
- Or a more sophisticated example might be to compare different routes to get to work, and collect some data on different days, then analyse the results to find which routes are fastest over a week; and then we can refine our study by collecting more data to see which routes are fastest on which days.
These may be only very simple examples of empirical methods, but they illustrate how we can act as “personal scientists” to solve everyday problems.
Sadly, in the US nowadays (and to a lesser extent elsewhere), almost half the population has given up on the scientific method, and instead is listening to “false prophets” of some churches, some media, and some political cults, like the Trump wing of the GOP; in India even astrologers still hold sway.
In US States where the majority vote was for Trump, there is little attention being paid to the evidence of rising cases of covid-19, in favour of anti-vaxx conspiracy theories that have no empirical basis, and therefore do not conform to the criteria of the scientific method. The resulting deaths and cases of Long Covid will be the result of failing to make use of the scientific method.
Conversely: China, for all its authoritarianism, still very much believes in the scientific method…
