Classify each item as either an example of preservation or an example of conservation. - A U.S. National Seashore is designated to protect shoreline from development so that the natural habitat and ecosystems are maintained | Preservation |
Classify each item as either an example of preservation or an example of conservation. - In the U.S. National Forest, hunting is allowed during certain seasons with limits on how much can be harvested. | Conservation |
Classify each item as either an example of preservation or an example of conservation. - Federally designated Wilderness areas are areas where nature is " untrammeled by man, where man himself is a visitor who does not remain". | Preservation |
Classify each item as either an example of preservation or an example of conservation. - In some U.S. National Forest, certain areas are opened each year for people to come in and chop firewood. | Conservation |
Classify each item as either an example of preservation or an example of conservation. - In the U.S. National Parks, no item may be removed from natural habitat without special permission. | Preservation |
Classify each item as either an example of preservation or an example of conservation. - The U.S. Fish and Wildlife service manages the to conserve habitat and animal populations. Hunting and fishing are allowed during certain seasons with limits | Conservation |
Classify each item as either an example of preservation or an example of conservation. - The Dep. of Envir. Quality publishes the catch limits for recreational fishing at the coast, limits change to protect populat. sizes & spawning sizes not overfish | Conservation |
To say that environmental science is mission oriented means it is | oriented toward solving problems. |
If everyone in the world lived a lifestyle similar to the average U.S. citizen we would need __________ more planets to support everyone. | four |
About ____________ of the world's people currently lack access to clean water, adequate diet, basic sanitation, and other essential needs. | 700 million |
Science investigates the natural world in a systematic manner. From the list provided, place the labels in the proper order on the flow chart to illustrate the scientific process. | 1. Identify question 2. Form testable hypothesis 3. Develop a test of the hypothesis 4. Collect data 5. Interpret result 6. Report for peer review |
The concept that the forces that shaped the world in the past are still operating today, and will continue to do so in the future is known as ____________ . | Uniformitarianism |
All scientific explanations have a level of ____________ because they are based on evidence (data), hence, our knowledge is always subject to change as new evidence appears. | Uncertainty |
Using careful observations of real, observable phenomena to understand fundamental processes and natural laws is called ____________ . | Empiricism |
The idea that the results from tests and experiments should be reproducible, otherwise the conclusions are probably incorrect is referred to as ____________ . | Repeatability |
Place the steps of the scientific method in the order that they occur. | Identify Question 1. Form testable hypothesis 2. Consult prior knowledge, Collect data to test hypothesis, If hypothesis is rejected 3. Interpret results 4. Report for peer review 5. Publish findings |
We can learn about the world by careful observation of empirical (real, observation) phenomena; we can expect to understand fundamental processes and natural laws by observation. | Empiricism |
Basic patterns and processes are uniform across time and space; the forces at work today are the same as those that shaped the world in the past, and they will continue to do so in the future. | uniformitarianism |
When two plausible explanations are reasonable, the simpler (more parsimonious) one is preferable. This rule is also known as Ockham's razor, after the English philosopher who proposed it. | Parsimony |
Knowledge changes as new evidence appears, and explanations (theories) change with new evidence. theories based on current evidence should be tested on additional evidence, with the understanding that new data may disprove the best theories. | Uncertainty |
Test and experiments should be repeatable; if the same results cannot be reproduced, then the conclusions are probably incorrect | Repeatability |
we rarely expect science to provide absolute proof that a theory is correct, because new evidence may always undermine our current understanding | proof is elusive |
To find out whether a theory is correct, it must be tested; we formulate testable statements (theories) to test theories. | Testable questions. |
A study of events that have already happened | Natural expiriment |
An experiment in which some conditions are deliberately altered while others are held constant to study cause-and-effect relationships. | Manipulate Expiriment |
An experiment in which neither the experimenter nor the subjects know, until after the gathering and analysis of the data, which was the experimental treatment and which was the control | Double-Blind Experiment |
An experiment in which those carrying out the experiment don't know, until after gathering and analysis of data, which was the experimental treatment and which was the control | Blind experiment |
