Q & A
What is the first step in the scientific method?
-The first step in the scientific method is the question, where a scientist proposes the problem they want to solve.
What is a hypothesis and how does it relate to a question?
-A hypothesis is a potential answer to a question at hand, often looking like a prediction about the outcome when the hypothesis is tested.
What is an experiment in the context of the scientific method?
-An experiment is an ordered investigation intended to prove or disprove a hypothesis, and it is where important data comes from.
How are observations different from the data collected during an experiment?
-Observations are statements of knowledge gained through the senses or scientific equipment, and they are crucial for collecting data during an experiment.
What does data analysis involve in the scientific method?
-Data analysis involves comparing the results of the experiment to the prediction posed by the hypothesis, based on the observations made.
What is the conclusion in a scientific process?
-The conclusion of a scientific process is a statement of whether the original hypothesis was supported or refuted by the observations gathered.
Do the steps of the scientific method always occur in the same order?
-No, the steps of the scientific method do not always occur in the same order. Real scientists may go back and repeat steps many times before they come to any conclusions.
What is an example of how the steps of the scientific method can be fluid?
-The example given in the transcript is troubleshooting an internet connection issue, where observations led to questions, which led to hypotheses and further experiments.
Why is it better to use the word 'elements' to describe the steps of the scientific method?
-It's better to use the word 'elements' because the first step, the question, does not always come first. Observations can come first and inspire the initial question.
How does the scientific method apply to the example of the internet connection issue?
-The scientific method applies by starting with an observation (no internet connection), forming a hypothesis (the problem is with the internet, not the laptop), conducting an experiment (checking the desktop's connection), making observations, analyzing the data, and drawing a conclusion.
What is the importance of repeating steps in the scientific method?
-Repeating steps is important because it allows scientists to refine their hypotheses, gather more data, and ensure that their conclusions are robust and reliable.
Can you provide a real-world application of the scientific method based on the transcript?
-Yes, the real-world application provided is troubleshooting an internet connection issue, which involves making observations, asking questions, formulating hypotheses, conducting experiments, and drawing conclusions based on the data collected.

Highlights
The scientific method is a set of procedures that scientists follow to gain knowledge about the world.
Steps of the scientific method vary widely among different scientific disciplines.
There are six key steps that characterize the scientific method: question, hypothesis, experiment, observation, data analysis, and conclusion.
A well-conceived question usually leads to a hypothesis, a potential answer to the problem at hand.
Hypotheses often look like predictions about the outcome of an experiment.
Experiments are ordered investigations intended to prove or disprove a hypothesis.
Observations are crucial for collecting data and are statements of knowledge gained through the senses or scientific equipment.
Data analysis involves comparing the results of the experiment to the prediction posed by the hypothesis.
The conclusion of a scientific process is a statement of whether the original hypothesis was supported or refuted by the observations.
The scientific method may not always follow a linear path; scientists may repeat steps or go back and forth between them.
The steps of the scientific method are more fluid and dynamic than commonly thought.
Observations can come before questions, and experiments can inspire new questions.
The scientific method is often iterative, with scientists repeating steps until they reach conclusions.
An example of troubleshooting an internet connection illustrates the fluidity and application of the scientific method in everyday life.
In the internet connection example, the process of elimination through hypothesis testing and observation led to identifying the problem.
The conclusion that the router was off was reached through a series of questions, hypotheses, experiments, and observations.
The scientific method is adaptable and can be applied to a wide range of problems, from scientific research to everyday troubleshooting.

when you first took science class in
school you probably learned the basic
steps of a scientific Investigation
you've likely heard of Words like
hypothesis experiment and observation
you may have even memorized a prescribed
set of steps the scientific method is a
set of procedures that scientists follow
in order to gain knowledge about the
world However the steps involved in this
scientific method vary widely among the
different scientific disciplines
chemists follow The Method a bit
differently than psychologists
geologists and botanists have their own
unique methods so is there really one
scientific method that encompasses all
of Science to find out we'll need to
learn more about the scientific process
there are six key steps that tend to
characterize the scientific method the
first step is the question This is the
part where a Scientist proposes the
problem that he wants to solve a
well-conceived question usually leads to
a hypothesis a potential answer to the
question at hand sometimes hypotheses
look more like predictions The Scientist
predicts What the outcome will be when
he tests his hypothesis The Scientist
test is also called The Experiment
experiments are ordered investigations
that are intended to prove or disprove a
hypothesis
important data comes from Performing an
experiment The Scientist has to make
observations of the results that he gets
for The Experiment an observation is a
Statement of knowledge gained Through
The Senses or Through The use of
scientific
equipment observations are crucial for
collecting data Once the results are in
The Scientist must begin his analysis
data analysis involves comparing the
results of The Experiment to the
prediction posed by the hypothesis based
on the observations he made The
Scientist has to determine whether his
hypothesis was correct then he sums up
his findings with a conclusion the
conclusion of a scientific process is a
Statement of whether the original
hypothesis was supported Or refuted by
the observations gathered the scientific
method usually employs all six of the
steps I mentioned but the steps don't
always occur in the same order real
scientists may go back and repeat steps
many times before they come to any
conclusions it's actually better to use
the word Elements to Describe the steps
since the first step question does not
always come First sometimes for example
it's an observation that came first and
spawned the Initial question likewise
observations that are made during an
experiment can inspire more questions
that scientists have to answer the
scientific method is much more fluid
than you might think Let me show you how
the steps can feed back and branch out
from one another with an example from my
own experience last weekend I had a
minor ordeal with my internet connection
at home I had started up my laptop and I
was frustrated to find that i couldn't
get a on the Internet I made the
observation that my laptop wasn't
receiving an internet connection I asked
myself a question is something wrong
with the internet itself or was it just
my laptop one way to begin answering
this question was to check the
connection on the desktop computer
quickly i formed a hypothesis If the
internet isn't working on the desktop
either then the problem is Beyond my
laptop computer The Experiment I
performed was to check the desktop's
connection and my resulting observation
was that the internet didn't work There
so by analyzing the evidence I was able
to form my first conclusion nothing is
wrong with my laptop and something is
wrong with the internet connection now
this conclusion answered my first
question But it still didn't get my
internet to work So I had to pose
another question where exactly was the
problem occurring in the chain of
internet devices was it the chord
between the modem and the router the
chord between the router and my computer
or was the problem in the router itself
I had to form another hypothesis if both
my internet chords are properly plugged
in then there must be a problem with the
router my experiment was to check both
chords and the router my observation was
that both chords were plugged in and
that the router was off I analyzed the
evidence and my conclusion was that i
couldn't Connect to the internet because
