Intro
What is environmental science?
The study of environmental problems and human impacts on the environment
What is a value justification?
A reason for valuing the environment.
What is the correct order?
A) Make a hypothesis, test the hypothesis, analyze the results, ask a question, draw conclusions, communicate results.
B) Ask a question, analyze results, make a hypothesis, test the hypothesis, draw conclusions, communicate results.
C) Ask questions, make a hypothesis, test the hypothesis, analyze results, draw conclusions, communicate results.
D) Ask a question, make a hypothesis, test hypothesis, draw conclusions, analyze results, communicate results.
C) Ask questions, make a hypothesis, test the hypothesis, analyze results, draw conclusions, communicate results.
What is a dependent variable, and which axis is it on in a graph??
The variable you measure that is affected by the variable that is changed, y axis.
What is extrapolation vs interpolation??
Extrapolation: Outside of known data values
Interpolation: Inside of known data values
Environmental science is interdisciplinary. What does this mean?
It contains many different fields such as biology, engineering, and geology.
What is the moral justification?
Valuing the environment due to a belief that the environment has a right to exist and it is our responsibility to care for the environment.
What is a scientific law and what does it need?
Describes what will happen in a given situation as demonstrable by a mathematical equation
What is the independent variable, and which axis is it on in a graph?
The variable that is changed to create a measurable result, x axis
Difference between a broken and continuous line graph.
Continuous line graphs connect the data points with a straight line that has a consistent/gradual slope, and broken line graphs connect data points with line segments that do not have a consistent slope and large jumps in slope.
Give an example on how an Engineer could contribute to environmental science.
Engineering is a branch of Physics by which matter and energy are made useful to humans in structures, machines, and products. Engineers could design/create something to help us study, preserve, or affect the environment.
What is the utilitarian justification?
Valuing the environment due to its benefit to humans economically or its direct necessity for survival.
What is a null hypothesis?
A prediction that there is no difference
What is a null hypothesis?
A prediction there is no difference.
What type of graph will be in your lab report?
A: Circle Graph
B: Bar Graph
C: Multiple Line Graph
D: Scatter Plot
C: Multiple Line Graph
What are some ways humans impact the environment?
There are many ways. We use resources from the environment for survival such as land and food. We impact ecosystems and animals due to our land and food use.
What is the ecological justification?
Valuing the environment due to the ecological importance and benefit of the system.
What is lag time?
Not all changes have immediate effects.
What is the difference between a theory, law, and hypothesis?
Law: Describes what will happen in a given situation as demonstrable by a mathematical equation
Hypothesis: A testable conjecture on how something works
Theory: Explanation about the physical world based off of laws, hypothesis, and data.
What are three things a graph should have?
Title, units, labeled axis, legend, scale
Why is studying environmental science important?
Humans are connected to and affect our environment. We have the ability to change our environment to what we wish it to be.
Why are value justifications important?
So we know what we value and how we wish to affect our environment. We change our environment to our values.
What is an example of an "irreversible consequence" in environmental science?
Irreversible in one lifetime or more. For example, cutting down an old-growth forest or soil erosion that could take hundreds to thousands of years to replace.
Why do you only change one variable at a time?
So you are certain that you are measuring the affect of only one variable.
Why is analyzing and sharing results of data important in science?
Without analyzing results, we cannot draw conclusion s from data, and without sharing results, researchers cannot use your results or verify them.
