1. Review the key Questions and Concepts for the chapter on page 5. Define environment, Define and distinguish among environmental science, ecology and environmentalism. Define and distinguish between an organism and species. What is an ecosystem? What are the three principles that nature has used to sustain itself for at least 3.5 billion years?

2. Define natural capital, natural resources and natural services. Define nutrient cycling and explain why it is important. Describes how we can degrade natural capital. and how finding solutions to environmental problems involves making trade-offs. Explain why individuals matter in dealing with environmental problems we face.

3. What is resource? Distinguish between a perpetual resource and renewable resource and gi8ve and example of each. What is sustainable yield? Define and give two example of a nonrenewable resource.

Define and distinguish between gross domestic product (GDP) and per capital GDP. Distinguish between more ? developed countries and less ? developed countries and give example of high- income, a middle- income and a low ?income country.

Scientists use a structured approach called the scientific method to answer questions and figure out problems. The scientific method includes making observations, developing hypotheses, testing these hypotheses, collecting data and analyzing results. There are controls, independent variables and depend variables involved.

For your initial post worth 15 points do the following:

Outline a situation you have encountered in your work or daily life in which you used the scientific method to solve a problem. Explain how you approached this problem by using the steps of the scientific method.

Observations – 3 points
Hypothesis – 3 points
Experiment – 3 points
Data Collection and Analysis – 3 points
Conclusion – 3 points
Make sure to provide at least 2 sentences for each step. Failure to do so will result in an automatic 5 point deduction for the post.

For your reply post to another classmate by Sunday at 11:59pm worth 15 points, do the following:

Review each of their use of the scientific methods
Then explain what you think would happen if you could change any of their variables or controls – 7 points (Provide at least 1 – 4 sentence paragraph of detail)
Predict what different outcome you would expect – 8 points (Provide at least 1 – 4 sentence paragraph of detail)
Failure to meet the sentence requirement will result in an automatic 5 point deduction for the post.
