What is a scientific theory?

the explanation of well-tested observation or experiments.

How is a scientific Law different from a scientific Theory?

Law describes observed pattern, Theory explains the pattern

manipulated variable is

a variable that causes a change in other variables

What does the responding variable do?

changes in response to the manipulated variable

A controlled experiment is one where

only one variable is changed at a time

Why are scientific models useful?

make it easier to understand things too big/small to observe

In an experiment, Drawing a conclusion means what?

explains how facts from an experiment apply to a hypothesis

What is the goal of any scientific method?

to better understand an observed event or solve a problem

the proposed answer to a question

What is FALSE about a scientific model?

It can never be replaced regardless of new information

according to notes/txtbk what was the conclusion to the experiment about staying drier in rain?

If you run you will stay drier in the rain

Like a giant lake of burning gasoline
Like an old satellite burning through the atmosphere

2
What is a scientific theory?
the explanation of well-tested observation or experiments.
the answer to a tough question
phenomena that have been observed for thousands of years
the conclusion of an experiment performed only once
3
How is a scientific Law different from a scientific Theory?
Law explains observed pattern, Theory describes pattern
a Law is a more complicated Theory
Law describes observed pattern, Theory explains the pattern
There is no difference
4
manipulated variable is
a variable that is always different
a variable that stays the same throughout the experiment
a variable that causes a change in other variables
a variable that doesn't change other variables
5
What does the responding variable do?
Changes based on another responding variable
changes in response to the manipulated variable
Does not change at all
changes based on a controlled experiment
6
Making an observation includes using
your books
an experiment
your senses
the radio
7
A controlled experiment is one where
only one variable is changed at a time
when a different variable changed ea. time experiment done
when 2 or 3 variables are changed at a time
When there are only two variables in the experiment
8
which of the following is not part of the scientific method?
asking a question
forgetting your question
testing a hypothesis
making an observation
9
Why are scientific models useful?
make it easier to understand things too big/small to observe
to make things that are easy to understand more complicated
to help sell Scientific merchandise
to make Theoretical Physics fun
10
A variable is
a hypothesis that changes over time
any factor that can change
an idea that changes over time
any answer that can change
11
In an experiment, Drawing a conclusion means what?
describes how facts apply to an observation
concluding ideas presented in a scientific journal
tells how a scientific theory explains a scientific law
explains how facts from an experiment apply to a hypothesis
12
What is the goal of any scientific method?
to better understand an observed event or solve a problem
to write a non-fiction article
to make things more confusing
to prove a Scientific Law
13
A Hypothesis is
the answer
a good question
an educated guess
the proposed answer to a question
14
What is FALSE about a scientific model?
It can never be replaced regardless of new information
it can help you visualize something as big as our universe
it can change/be replaced whenever new info is discovered
it can help you visualize something as small as an atom
15
according to notes/txtbk what was the conclusion to the experiment about staying drier in rain?
Wear a Rain Coat
It doesn't matter if you walk or run you'll be equally wet
If you run you will stay drier in the rain
If you walk you will stay drier in the rain
