Hi. My name is Mr. Koslowski. Welcome to "What is science?" lecture. This is actually Unit 1/Module 1 Powerpoint.
This is the first of our flipped lecture series of the year so I hope you enjoy.
Again, if you have any questions about flipped lectures or a flipped classroom
please feel free to contact me
So, What is Science?
I'm going to start out for seeking an answer this question by showing a video. This is called popcorn the if you think about it in a popcorn is
something that I like to enjoy at the movies.
I hope you do too. And when you pop the popcorn to watch a movie, usually you put it in a microcwave, you have the tiny little bag,
it starts to expand and it the kernnels start to pop.
Well, how do this happen?
What other questions do you have?
What are possible solutions to this problem?
I pose these three questions because I have a unique video that I want to show you
These are three questions. Now think to yourself, how did this happen? U must have some other questions about this.
What are some possible solutions to figure out how this occured?
What I just previewed there was basically
what scientis do on a daily basis. So, if we ask the question, what is science?
Well science is basically asking questions to find out something about the world the universe that we live today.
In science, it's a very organized way of studying things to find answers to these questions
There are many different types of science that exist today
in science there's a organization that can be used to describe how we solve a problem and this series of procedures
is called the scientific method
It is an organized method of
approaching a problem or question that is posed. . . .Problem, Hypothesis, Experiment, Observation, Conclusion
This is known as PHEOC
and this is a very simple way of describing the scientific method.
However there's also other ways that we can solve problems. I always say, " there's more than one way to skin a cat." in class
We will be looking at more complex ways throughout the year of how the scientific method can be applied to different types of problems
Here we have a graphic of the scientific method that shows scientific method broken down into six steps.
There's a lot more detail behind each of those steps. As you can see
(reading the details in each step)
There is a lot of detail behind all of these steps
Scientific methods will be used more in class.
What happens after we found a scientific experiment that is conducted?
Basically what we need to do is report the results. We do that
in many different forms,
raw data from the lab
and you analyze the data
and basically then draw a conclusion. A conclusion is what you think of occured.
Basically what the result was.
and we do this in science in the form of what we call an evidence based-response
An evidence-based response is a way to write conclusions and to report the results
the way we do this in 7th grade
we form basically a paragraph. The paragraph is called CER. CER stands for three things
Claim, Evidence, & Reasoning. So if I ask you the question, what three things are involved in an evidence based response
you're going to automatically raise your hand and say CER, Claim, Evidence, Reasoning
so what is CER exactly? Claim is what do you know?
and you get that by analyzing the results from your lab.
The evidence is, How do you know that?
Evidence is always going to support your claim
Finally your reasoning. Why does your evidence support your claim?
These three things make an evidence based response or an explanation which is proper in science.
here is an example
air is matter we found that the weight of the ball increases each time we pumped more air into it
This shows that air has weight
one of the characteristics of matter
well if we look at is this paragraph this evidence based response
We know that "Air is matter" That is our claim. We're making a statement about what we observed.
The second sentence, "We found that the way the ball increases each time we pumped more into it." - That's our evidence.
We gain evidence through observations. There is different types of evidence. There is qualitative
and quantitative. Qualitative evidence, which is the example of this paragraph, is something that we basically observe about the characteristics of
an object or what was occurring in the lab. Quantitative data is like measurements.If we
were measuring an object. The mass of an object.
Lets say we're measuring the mass of the air in this claim or this experiment. That would be qualitative data.
In the last sentence this shows that air has weight, one of the characteristics of matter
That's your reasoning. The reasoning ties it all together back to a scientific concept that we were talking about or discussing.
what happens after conclusion?
Generally alot of the labs are repeatable.
If a lot of data collected from several experiments over a long period of time
that all support the same hypothesis
this is called a theory
A theory is a series of statements or observations that say similar
things relates to the hypothesis
There is alot of them in science
theories are different than laws. A law is a statement of
how things work in nature that seems to be true of all the time
so scientific laws & theories, there is a difference between them. How are they different?
Laws generally don't change because they are about
observations of the natural world that most scientists agree with.
theories are data in a series of statements that support a hypothesis
and people get fuzzy about theories because theoires can change over time with new evidence. A lot of people think that a scientific
theory is the way it is
but its really not
They support a hypothesis.
They can change with new evidence that is collected through new experiments
They will change over time
