1.This first part of the Individual Research Project is an Outline and Annotated Bibliography. The Outline should provide a very brief ...

tline should provide a very brief overview of what you think you will do in the Policy Brief. The Annotated Bibliography requires you to summarize at least three peer-reviewed scholarly sources you will cite in the Policy Brief. This assignment is designed to get you thinking about your topic in a way that clearly anticipates the writing you will do for the Policy Brief. We want you to brainstorm and do a bit of research well in advance of the deadline for the Policy Brief and, most importantly, we want you to put your ideas down on paper so that we can give you feedback before writing the actual Policy Brief. In other words, we are asking you to submit an Outline and Annotated Bibliography so that we can help you write the best Policy Brief possible. Your Outline should be divided into the following five sections and should be written in complete sentences: I. Audience: Identify the audience you are addressing and consider what that audience is interested in. Who are you talking to in the Policy Brief and what does this suggest about the approach you should take? (75-100 words). II. Problem: State how you know the issue exists. What is the proof that students need to improve this skill? (125-150 words). III. Importance of Problem: Indicate why this problem matters. What are the consequences of the problem not being addressed? Why do students need to improve this skill? (100 words) IV. Solution: Identify your preferred solution. What solution will work in your context and why? (75-100 words) V. Alternative Solution: Identify at least one other possible solution. What other solutions did you consider? (75-100 words) The total length of the Outline should be between 450 and 550 words. When you submit your Outline, you must also include an Annotated Bibliography. An Annotated Bibliography is an alphabetical list of research sources that provides bibliographical data (the title, author, date, publisher, etc.) and a short summary or annotation of the source. Your Annotated Bibliography should contain a minimum of three scholarly or peer-reviewed sources, each with an accompanying annotation that is between 150 and 250 words long. The annotations must summarize the research question or thesis, research methodology, results, and conclusion. Annotations must include summaries and paraphrased information, NOT quotations. A good annotation will include two separate paragraphs: 1) a paragraph summarizing the research question or thesis, research methodology, results and conclusion; and 2) a paragraph commenting on why this source is relevant for your research.

2. Research Project & Presentation Your Task: Create a Google Drive Presentation that demonstrates your knowledge and understanding of significant concepts in ...

your knowledge and understanding of significant concepts in Biology and Chemistry. Describe the relationship of some or all of the significant concepts that you identify through the use of a specific example. General Format of the Presentation: Twelve Slides (Minimum). Two Appropriate and Interesting Videos - length of the video must be reasonable and content must be focused. Three interactive links must be included. Appropriate and well-placed pictures and illustrations. 1 - 2 uses of audio recordings - i.e. you describing knowledge that contributes to your Presentation. Minimal use of text alone. Multimedia used to convey knowledge and understanding on each slide. Content: 3 Big Ideas in Biology - *must include the basic unit of life, the Cell, and why it is important to the structure, function, and evolution of life on Earth. 3 Big Ideas in Chemistry - *must include the basic unit of matter, the Atom, and why it is important to the structure, function, and evolution of life on Earth. Specific Example: Pick Your Own Example that combines some or all of your big ideas from Biology and Chemistry and describe how those big ideas affect the structure, function, and evolution of your example. Example 1: The Ocean Think of the ocean as a biome made up of non-living and living things. How do your big ideas in biology and chemistry relate to the structure, function, and evolution of the oceans? Include descriptions (examples) of the relationship between the non-living (chemistry) and living (biology) things in oceans. Example 2: A Bear Think of a bear as a living organism that is made up of and relies upon non-living (chemistry) and living (biology) things. What is the bear made up of? Cells that form ________ that form _________ that form _________ that form the bear. What does a bear eat? What nutrients does a bear get from the specific foods that it eats? How do these nutrients (chemical elements of a bear’s diet) contribute to the growth, function, and structure of the bear? **You may use one of the examples provided or pick your own. Steps: Step 1: Identify 3 big ideas in Biology ( 1 idea must be the Cell, basic unit of life) Step 2: Identify 3 big ideas in Chemistry (1 idea must be the Atom, basic unit of matter) Step 3: Choose your specific example. Step 4: Slide 1 - Project Title Slide. Step 5: Slides 2 - 11 (minimum) - Body of Project. Step 6: Slide 12 - Conclusion. Step 7: Turn in your presentation for my revisions. Step 8: Revise. Step 9: Turn in your final research project presentation for grading.
