What is the first step of the Scientific Method?
Observation/Ask a Question
Microscopes and telescopes are examples of:
Science Tools
Define hypothesis.
A scientific explanation for a set of observations that must be testable. Also known as an educated guess, or a prediction and has not yet been proven or disproven.
_____________ data involves numbers and must be obtained by counting or measuring.
Quantitative
What is the second step of the Scientific Method?
Create a Hypothesis
When something new is created it is called an:
Invention
____________ is the information gathered from making observations.
Data
True or False: Do scientists normally keep their data, research, and all other aspects of an experiment unorganized and in a non-orderly fashion?
FALSE.
What is the third step of the Scientific Method?
Designing a Controlled Experiment
___________________ collect and organize information in a careful, orderly way, looking for patterns and connections between events.
Scientists
The factors in an experiment that can be changed are called _____________.
Variables
What is a control group?
The group in an experiment that does not receive the variable being tested. It is instead kept neutral and then used as a comparison to measure how the other tested subjects, also known as the experimental group, react.
What is the fourth step of the Scientific Method?
Analyze and Record Results
Scientists must use their _____________ to observe things.
Senses
What is an experimental group?
The group in an experiment that receives the variable being tested, and therefore shows the effect it has on the group.
______________ data refers to descriptions and involve characteristics that cannot be counted.
Quantitative
What is the fifth step of the Scientific Method?
Draw Conclusions
True or False: Science is an organized way of using evidence to learn about the natural world.
True
True or False: Up to three variables can be changed during an experiment.
False - Only ONE.
Define the Scientific Method.
