Environmental Science: Chapter 2
An example of a(n) ________________________________ model is a flow chart showing how water mives between the atmosphere and Earth's surface.
Conceptual
One step in a decision-making model is the explore both positive and negative _______________________ of each option.
Consequences
The____________________________________ is the group that does not receive the experimental treatment in an experiment.
Control group
When scientists are not able to use an experiment to test a prediction, ______________________ can be examined.
Correlations
The procedure used by scientists to test a hypothesis is called a(n) ________________________________.
Experiment
In an experiment, the group that receives the experimental treatment is called the ________________________________.
Experimental Group
The ____________________________ consists of a series of steps used by scientists to identify and answer questions.
Experimental Method
Information known as a(n) _________________________________ is gathered by using the senses.
Observation
Three-dimensional models you can touch are referred to as _____________________________ models.
Physical
A(n) ___________________________ is a logical statement about what will happen in an experiment if the hypothesis is supported.
Prediction
The chance that an event will happen is known as _____________________
Probability
The probability of an outcome that is unwanted occurring is called __________________________.
Risk
In statistics, the group of individuals used to represent the population is called the ____________________.
Sample

Skepticism
Scientists use statistics to describe ____________________________________, groups of similar things they are interested in learning more about.
Statistical populations
A(n) _____________________________ is one type of graph that is particularly useful for organizing and comparing experimental data for several things in one graph.
