Complete the phrase: “One goal of science is to __________ and __________ the laws of nature.”     
Definition
  1. Discover and describe. 

Term
Complete the phrase: “Science can only address questions which are _________ and __________.”     
Definition
Objective and Empirical
Term
What does it mean for a question to be objective?     
Definition
  1. Basically, that there is “a” correct answer, and that answer is not subject to an individual's feelings, biases, or opinions. 

Term
What does it mean for a question to be empirical?
Definition
That data relevant to the question can be collected using the five senses or instrumentation that extends the sensed. 
Term
What is a research (or alternative) hypothesis?     
Definition
A researcher's best guess as to the underlying nature of a given phenomenon (i.e. their best guess as to an explanation). 
Term
What is a null hypothesis?     
Definition
The sum total of all other explanations for the phenomenon.    
Term
How are the research and null hypotheses related to each other?     
Definition

They are mutually exclusive. The research

hypothesis says that the answer is “X”, while the null hypothesis says the answer is “something other than X”. 

Term

In a scientific investigation, the researcher ultimately makes a decision to accept or reject which of the two

hypotheses?  

Definition

The null hypothesis. This helps prevent our personal biases from leading us to accept an idea as correct

when it really is not. 

Term
What is the typical minimum level of confidence required before accepting or rejecting a hypothesis?     
Definition

95%. In many

disciplines, the required level of confidence is higher. 

Term
Define the following terms: theory, model, and law.     
Definition

A law is a summary of observation – it tells us “what” we

observe. A theory is an attempt to explain those observation, i.e. “how” it happens. A model is any “picture” or

representation of the system that helps us understand how it works. 

Term
Which of these terms generally refers to observations?    
Definition
Law
Term
Which of these terms generally refers to explanations or interpretations?     
Definition
Theory
Term
What is the difference between a theory and a hypothesis?    
Definition

A theory has a wealth of supporting evidence, while a

hypothesis is a sort of untested (ore perhaps not thoroughly tested) starting point. 

Term
True or false: with enough supporting evidence, a theory will eventually become a law.    
Definition

False. Since theories pertain

to explanations, and laws pertain to observations, a theory cannot become a law. 

Term

Complete the phrase: “Empirical evidence consists of measurements and observations using _______ or

__________.” 

Definition
The five senses or instruments that extend the five senses.    
Term

Complete the phrase: “When standard (or accepted) data or results are known, _________ experiments will agree

with those standard values.”  

Definition
Accurate.   
Term

Suppose an archer shoots a tight group that is not centered on the bulls-eye. Is this archer accurate? Is this archer

precise? 

Definition
They are precise, but not accurate.    
Term
True or false: Anecdotal evidence is worthless.     
Definition

False. It cannot be used as the basis of a scientific investigation, but it

may lead the investigator in the right direction. 

Term
What is “critical review”?     
Definition

The formal process by which scientific ideas and results are scrutinized by experts and by

the scientific community in general. 

Term
When a manuscript is submitted to a peer-reviewed journal for publication, what happens? (Outline the steps.)    
Definition

The editor checks to see if the content is appropriate for the journal, and if it is, passes a copy of the manuscript on to experts in the field. The experts review the manuscript and make a recommendation to publish it, or request that certain revisions be made first. Once the revisions have been appropriately made, the editor may then decide to publish the manuscript, after which it is subject to the scrutiny of the entire scientific community.

Term

The “cycle” of the scientific process (prediction, experiment, analysis, and refinement) continues through how

many iterations?

Term
  1. Understanding the scientific aspects of this topic [climate change] can aid society in ____________.”  

Definition
Making correct decisions
Term
What is the greenhouse effect?
Definition
 Visible light from the Sun travels through Earth's atmosphere, is absorbed by the surface, and then re-emitted as infrared light. Infrared light, though, cannot pass through the atmosphere as easily as visible light, so some of the energy is retained and/or reflected back toward the Earth. 
Term

Definition
57°F (14°C).
Term
What would the annual average temperature on Earth be without the greenhouse effect?    
Definition
3°F (-16°C).    
Term
What are natural climate forcings? Give several examples.     
Definition

Anything natural that can affect the climate: variations in

Earth's orbit, variations in solar intensity, volcanic activity, etc... 

Term
What are anthropogenic climate forcings? Give several examples. 
Definition

Anything that man does that can affect the climate:

deforestation, carbon released into the atmosphere by burning fossil fuels, passing gas (methane), etc... 

Term
From a carbon cycle standpoint, what is the difference between burning coal and burning wood?
Definition

 The carbon in the wood was put there (via photosynthesis) a few hundred years ago, typically. So burning wood doesn't really affect the

equilibrium levels of CO2 in the atmosphere. The carbon found in coal, on the other hand, has been buried under the Earth for the last 100 million years or so. There is no additional photosynthesis to balance out the carbon that we release when we burn coal. 

Term
Complete the phrase: “Because the question of global climate change is an ________ one, the answers do not depend on _________________.”

When does a scientific theory become a scientific law?    
Definition
Never. Scientific laws summarize observations, i.e. they describe “what”. Scientific theories attempt to explain the fundamental workings behind those observations, i.e. they attempt to explain “how”. 
Term

Consider the target shown to the right. Is the archer who shot the arrows accurate? Is he/she precise? 

not hitting bullseye but all close

Definition
They are precise, in that they keep “getting the same answer”. They are not accurate, however, because the “answer” they are getting is not the right one. 
Term
What minimum level of confidence is typically required before accepting or rejecting a given hypothesis?

Definition
95%.
Term
Why do scientists ultimately make a decision to accept/reject the null hypothesis (instead of the research hypothesis)?    
Definition
It is to eliminate, as much as possible, their own personal bias. The research hypothesis is the investigator's best logical attempt at explaining what happens. As such, they are predisposed to want to accept that hypothesis (“after all, I'm a bright person and it's very unlikely that I'm wrong.”) By requiring the rejection of the null hypothesis, the researcher is required to conduct tests that go beyond the scope of his or her research hypothesis – i.e. they are required to eliminate other possible explanations, too. 
Term
What is critical review?
Definition
The formal process whereby scientific work is subjected to the scrutiny and skepticism of experts and other scientists.    
Term
What specific things happen in the critical review process?    
Definition
A manuscript is provided to a journal. The editor decides if the content is appropriate, and if so forwards the manuscript on to three or four experts. The experts review the manuscript to make sure the conclusions are supported by the data, and that everything appears to have been done correctly. They also ensure that a sufficient amount of detail is provided that another person could replicate the work, if needed. They then make a recommendation to the editor. If the editor and experts are satisfied, the manuscript is then published, at which point it becomes available for the rest of the scientific community to review. 
Term
Summarize the steps taken in a scientific investigation.
Definition

In a nutshell: ask a question, formulate a hypothesis, make a prediction, perform an experiment, analyze your data, accept or

reject the null hypothesis.

Term
What is believed to be the primary cause of climate warming over the last several decades? 
Definition
Carbon dioxide (CO2) released from burning fossil fuels, an anthropogenic forcing.
Term
What is “cap and trade” supposed to do?
Definition
Limit the amount of carbon dioxide we (as a nation) release into the atmosphere each year.
