How does science work?

Science is just a method, a tool. Used properly, it works very well.

Observation, hypothesis, testing, reformulation of hypothesis, further testing, starting form very simple questions, gradually refining and narrowing down your questions, gradually ruling out what doesn't work, and slowly finding out what does work...leading eventually to an explanation, i.e. a conclusion--but always a conclusion that is subject to further testing.

Example: Your TV set doesn't work. You first ask, "why?" Now you start asking more specific, testable questions, e.g., "was it plugged in?" So you check. It is plugged in, so that's not it. So you then ask, "is the outlet bad?" You pull the plug and plug it in a different outlet that you already know works ok. TV set still doesn't work. "Has the circuit breaker shut off the circuit?" No. "Is there a loose connection inside the TV??" No, it's fine. "Is the on/off switch bad?" So you test it with a meter and find that the switch is broken. Your tentative explanation is that you have a bad switch. Now you test this explanation: change out the old switch for a new one. Bingo--the TV now works. Congratulations: you have just used a scientific approach to solve a problem.

science works in so many ways, that sometimes you just don't notice it.

example, as you use your fingers in typing, the myosin and tropomyosin in your muscle fibers uses calcium and other materials to contract and relax those muscle. and that's science(specifically, biology).

other examples:

photosynthesis in plants, gravity in earth, energy and forces we're using in our daily lives.

science is all around us. and it will always be until the end of the time.

K.I.S.S

Keep it simple stupid

Find a problem, try to solve the problem by researching, making a hypothesis, designing an experiment, recording data and figuring out the problem.
