Physical Science Chapter 2- Scientific Processes

The information you collect in an experiment in order to answer a question is called 

• evidence.
• hypothesis.
• variable.
• opinion.

The process of learning that starts with asking questions and proceeds by seeking the answers to the questions is called

• natural law.
• theory.
• inquiry.
• variable.

To figure out an answer using logical thinking is called

• reduction.
• induction.
• deduction.
• serendipity.

Scientific theories are always being tested by experiments

• True
• False

Variables that are changed in an experiment are called

• trials.
• procedures.
• control variables.
• experimental variables.

A scientific theory is a 

• statement that explains a complex idea and is supported by much evidence. 
• statement of observed facts.
• general statement that is accepted as true.
• scientific approach to problem solving.

An event during which an important discovery is made accidentally is called discovery by:

• trial and error.
• scientific method.
• serendipity.
• design.

The set of rules that explains how everything in the universe works are called

• hypotheses
  hypotheses.
• deductions.
• theories.
• natural laws.

In order for evidence to be considered scientific,it must be

• the opinions of an important scientist.
• objective and repeatable.
• deduced.
• testable.

What does it mean for scientific evidence to be considered objective?

• The evidence describes only what actually happened as exactly as possible.
• The evidence can be seen independently by repeating the same experiment the same way.
• The evidence includes the input of important scientists.
• The evidence includes opinions and feelings.
