Casini Project

You have the option to do an extra credit project where you research the Casini project that NASA just completed on Monday, Sept. 17, 2017. You will explain how the project fits with the scientific explanations talked about in class (a copy is below). For each of the scientific explanations, you will write a paragraph with at least 5 sentences (1 intro sentence, 3 body sentences and 1 summary sentence) as well as an introductory paragraph and conclusion paragraph. 8- paragraphs total to get all possible points. See rubric (rubric will be added later).

If you choose to do this project, you can get up to 5 points. If you choose not to do this, you’re not show the type of excellence that I would expect that a student with a grade of 95 or higher to get; therefore, the highest grade you can get this quarter will be 95 if you don’t do this project.

Scientific Explanations

Scientific explanations are based on empirical observations or experiments. The things we investigate we can investigate through out senses as well as extensions through technology.

Scientific explanations are made public. That means that scientists publishes their work when they are done, discuss their results with reporters and government agencies and share their results at meetings and over the internet with other scientists.

Scientific explanations are tentative. (Tentative means something can change. For example, we could say that my birthday part is scheduled for Oct. 6, but it may change to Oct. 7 if I get tickets for the baseball playoffs.) Tentative means that the answer is the best explanation we have at the time, but the answer can change later.  Usually, as new data and new ideas come in, our understanding improves.

Scientific explanations are historical. They are based on the work of scientists who came before us.

Scientific explanations assume cause-effect relationships. Much of science is directed toward determining causal relationships and developing explanations for interactions and linkages between objects, organisms, and events. Distinctions among causality, correlation, coincidence, and contingency separate science from pseudoscience.

Scientific explanations are limited. Our understanding of the cell is limited because microscopes can only see so much. And, our understanding of our bodies is limited because x-rays and MRI scans can only see so much detail. Additionally, when we learn about something, these things cannot be applied to other things. For example, when you learn about how bicycle brakes work, you can’t apply all of it to how tractor-trailer brakes work. Our scientific explanations don’t apply to all areas, but only to certain ones.
