Nature of Science
The ___________ ___________ is a step-by-step process to solve a problem.
Scientific Method
The “__________” is often a term used to describe the natural world.
In fact, the _________ includes all living things and the nonliving things with which they interact.
Environment
Experiments are models in which the conditions are controlled to produce a result. In an experiment there are 2 groups, what are they?
-Experimental Group
-Control Group
What is Environmental Science?
•The study of ecology as well as focusing on how humans affect the environment and ways to address environmental problems.
An ability to evaluate information and opinions in a systematic, purposeful, efficient manner
Critical Thinking
A ______________ is a possible explanation to the question and it must be able to be tested.
Hypothesis
Resources must be used at a sustainable rate - explain what this means.
The resource must be used and replaced at the same rate.
Two groups of students were tested to compare their speed working math problems. Each group was given the same problems. One group used calculators and the other group computed without calculators. What is the constant variable in the experiment?
Math Problems
Environmental Science is an Interdisciplinary Science - explain what this means.
Variable that changes as a result of the independent variable. It is used to measure the results of the experiment.
Dependent Variable
List the three types of variables in an experiment.
Constant Variable
Independent Variable
Dependent Variable
What is a renewable resource? Give one example.
- a resource that is naturally replenished over short periods of time.
- Sun, water, and topsoil
Mr. Krabbs has created a new sauce that he thinks will reduce the production of body gas associated with eating crabby patties from the Krusty Krab. He recruits 100 customers with a history of gas problems. He has 50 of them (Group A) eat crabby patties with the new sauce. The other 50 (Group B) eat crabby patties with sauce that looks just like the new sauce, but is really just a mixture of mayonnaise and food coloring. Both groups were told that they were getting the sauce that would reduce gas production. Two hours after eating the crabby patties, 30 customers in group A reported having few gas problems and 8 customers in group B reported having fewer gas problems. Which group is the control group?
Group B
In regard to human population, what is an ecological footprint?
An ecological footprint is a measure of the demands made by one person or group on global natural resources.
Variable that is altered in the “experimental” group. It is the variable being tested.
Independent Variable
The goal of any science is to use ___________ to make ___________.
Observations, predictions
What is a nonrenewable resource? List one example.
-A resource that takes a long time to replenish
-Fossil Fuels (millions of year underground - plankton and plants)

The new sauce
An ecological footprint is a measure of the demands made by one person or group on global natural resources. What does this include? (2)
the materials and resources consumed AND the resources needed to dispose of the waste produced.
An explanation or idea accepted by a substantial number of scientists
Scientific Theory
List the Steps of The Scientific Method (in correct order).
1. Make observation/ask a question.
2. Do background research.
3. Form a hypothesis.
4. Test your hypothesis.
5. Analyze data/results.
6. Draw conclusions.
7. Publish results.
Two major events have changed the course of human history and the way we interact with natural resources.
List the two major events.
-Agricultural (farming) and Industrial (production of machinery) Revolution

Two hours after eating the crabby patties, 30 customers in group A reported having few gas problems and 8 customers in group B reported having fewer gas problems. What is the dependent variable?
Amount of Gas Production (or reduction in gas production)
What is the "Tragedy of the Commons?" List one example.
When a shared (common) resource is unregulated, individuals will consume it at a selfish rate.
Define Science.
An organized way of using evidence to learn about the natural world.
