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.

Bar Graph

Numeric information called _______________________ is gathered in an experiment.

Data

The first step in the decision-making model is to _____________________________________________.

Gather information

Maps and charts are examples of _____________________________________ models.

Graphical

A(n) _______________________________ is a testable explanation for an observation.

Hypothesis

Equations used to represent how a scientific process works are called _____________________ models.

Mathematical
