Document Summary

Env 221h lec 1- scientific worldview: some people think science/tech is the root of env problems. Advanced techs: scn is a way to understand the world and it uses a explicit approach to attain that understating, scn seeks to explain how things work, involving only natural causes. Scn can only studied natural conduct; it cant really study social: scn is a way of knowing things/process of discovery, scn isn"t absolute; we just learn more about certain things as days or yrs go. Ex: today vitamin d is good tmrw it is bad because scn has attained more info on vitamin d: new studies will come out and disprove things, scientific method: Money: case study: northern cod fisheries collapse. The cod pop was os dense at this time in cnda. You didn"t even need specific tools to get the cod (basket was enough) The role of a fishery scientist is to develop info on bio/pop dynamics of fish stocks.

The scientific method is the backbone of every science experiment, but it's not just for scientists. Most people unconsciously use the scientific method on a daily basis, for example, when performing tasks like cooking or budgeting. In order to help you to better understand the scientific method and the process used, I would like you to give an example of something you have done recently in which you used the scientific method.

In your main post, please trace each step (given below), and don't forget to include your hypothesis and whether you accepted/rejected it at the end.

Steps of the Scientific Method:
1) Make an observation
2) Ask a question
3) Do background research
4) Form a hypothesis
5) Conduct an experiment
6) Analyze your data
7) Make a conclusion --> Do you accept or reject your hypothesis?

The scientific method allows us to pose questions, test questions, and analyze results. Through observation and research we begin to understand the world around us. Consider research you have read about or been a part of and analyze the following in one page: Was the Scientific method followed? How? What pieces were or were not part of it? (Randomization, study type, placebos, etc.) For the second part, present a research project you would like to propose in approximately one page. How can it help us learn about basic principles of behavior? How can you use the scientific method to find and address possible problems in your research design? This paper should be 2pages in length and use APA formatting (cover page, paper body formatting, citations, and references

Scientific Method Exercise
Identify a situation in which you applied the scientific approach to solving a problem. Share your thinking! The problem you choose to write about can be very simple, such as: my flashlight won't work, or my car won't start, or I baked muffins and they were flat ( didn't rise properly) , or the toilet won't flush properly, or better yet, think of your own. These probably don't sound like "science" problems, but it is most likely that you would use the scientific method to solve them, without even realizing it. Avoid using people problems and child or pet behavior issues as your "problem." Follow these steps to create your first writing assignment:

1. Describe the situation and your observation,
2. Describe your hypothesis to explain the observation.
3. Describe your further observations or experiments to test the hypothesis. Be sure your hypothesis is one that can be tested. Consider what you might use for "controls".
4. Was the hypothesis correct? If not, can you find a better one? Or do you need a better experiment? If so, what would it be?

The assignment should be formatted as follows: Be sure to include the labels, so it is clear that you recognize and identify each step in the process.
Problem: (briefly describe your problem here)
Question: (This may be a "how" or "why" question that you will formulate a tentative answer to. Your tentative answer is your hypothesis.)
Hypothesis: (State the answer to your question above. This is your "best guess" regarding the answer to the question.)
Prediction: (This describes your experiment very briefly and states the outcome you expect that would support your hypothesis)
Experiment: (Describe how you tested your hypothesis)
Results: (Describe what happened, and whether the results supported or failed to support your hypothesis)
