[h]Interactive Reading: What Science Is and Isn’t
[i]Drag the terms on top to the correct spot in the reading.
[q labels = “top”]
a. Some definitions of science
What is science? Let’s start with a few definitions.
Science is
- Knowledge that’s obtained and tested through the scientific __________ (adapted from merriam-webster.com).
- Knowledge of the physical or material world gained through observation and _______________ (adapted from com)
- A systematic activity that builds and organizes knowledge in the form of _________ explanations and predictions (from Wikipedia).
As all of these definitions point out, science is a search for understanding about the natural universe. But what makes science different from religion or astrology, which are also systems of ideas that search for understanding?
[l]experimentation
[fx] No. Please try again.
[f*] Correct!
[l]method
[fx] No. Please try again.
[f*] Great!
[l]testable
[fx] No, that’s not correct. Please try again.
[f*] Good!
[q labels = “top”]
b. Science is limited to what we can observe
To begin with, science is limited. Science can only study things that are a part of the ________ (as opposed to the supernatural) world. Things that are beyond nature (God, demons, ghosts, Spirits) are outside of what can be scientifically studied. Whether or not you believe in God, demons, or ghosts is your choice. But all of these are outside of the boundaries of _________ explanation.
Why? It’s because science is based upon ideas that can be proved to be correct through ____________ and experimentation. If you can’t perceive something, either directly with your senses, or indirectly through instruments (like microscopes, telescopes, light or sound sensors, chemical sensors, and so on), then it’s not something that you can scientifically study. A good rule of thumb is this: if you can ________ it, then it’s probably something that you can study scientifically.
[l]measure
[fx] No, that’s not correct. Please try again.
[f*] Excellent!
[l]natural
[fx] No, that’s not correct. Please try again.

[l]observation

[f*] Good!
[l]scientific
[fx] No, that’s not correct. Please try again.
[f*] Great!
[q labels = “top”]
c. Scientific ideas are verifiable and testable.
Note that a single observation isn’t enough. Many people, for example, claim to have observed miracles, or demons, or UFOs. But in science, valid evidence requires observations that can be __________ on demand. The gold standard for scientific observation is the experiment. Experiments involve observations that occur under carefully __________ conditions. During an experiment, the goal is to see if something can bring about an effect in a predictable, repeatable way.
The evidence that comes out of experiments can be used to develop or confirm a scientific explanation. For an explanation to be scientific, it must be capable of being proved _________. Think about it like this: a scientific explanation makes a testable prediction. As long as that prediction turns out to be correct, the explanation will stand. However, if the ___________ fails, then the explanation will have to be modified to match this new observation.
[l]controlled
[fx] No. Please try again.
[f*] Good!
[l]prediction
[fx] No. Please try again.
[f*] Correct!
[l]repeated
[fx] No. Please try again.
[f*] Correct!
[l]wrong
[fx] No, that’s not correct. Please try again.
[f*] Excellent!
[q labels = “top”]
d. What science is not
To hone our ideas about what science is, let’s look at some things that science is not.
- Science is not based on belief. A belief is a feeling, something that you know inside. Scientific ideas, by contrast, need to be objective—they have to come from __________ outside of you.
- Science is not based on __________. It doesn’t matter whose explanation it is. The only thing that matters in science is whether the evidence gained through observation and experimentation.
- Science is not democratic: the vast _________ can hold an idea that is completely wrong.
- Science is not fair: you can spend your whole life supporting an idea that turns out to be wrong.
- Science is never __________. Some very well established explanations have, in the past, been found to be incorrect, and it’s a sure thing that some explanations that we think are correct now will prove to be incorrect in the future. Given changing observations and evidence, scientific ideas have to be modified or sometimes entirely overthrown. And as disorienting as that might be, it’s a good thing: it gives us better _______________ of the world.
[l]authority
[fx] No, that’s not correct. Please try again.
[f*] Correct!

[h] Quiz: What Science Is, and Isn’t
[i] If you haven’t taken a sciencemusicvideos quiz before, here’s how it works:
- Each question is multiple choice, but the entire quiz is like a series of flashcards.
- If you get the question right, it comes off the deck. If you get the question wrong, it goes to the bottom of the deck, so you can try it again.
[q] True or false: science can only study things for which there is evidence.
