These topics form a foundation in science and research.They also are a window into understanding the world around you and how it works.Your assignment is to find four (4) articles based in a current research topic.They should have been published in the last year; believe me there are plenty of them out there.The article should be based in one (or more) of the topics above.Read the article (that tends to make the process a lot easier).
To complete the assignment, you will turn in:
- A paragraph summary of the article (3 pts):This should be a short summary of the article, are not looking to see a novel.But, I do want to see that you read the article and understand its purpose.
- A short vocabulary list (2 pts.): Science has a language all its own, there are words not used in every day conversation that are imperative in communicating.You do not need to rewrite Webster’s Dictionary here.Pull out several words that are from a biology vernacular (for example in an article about DNA you might run across a word like ‘helicase.’
- List the Lab’s that have done (or will do) that apply to the article (2 pts.) What labs might be useful in understanding what has been researched or presented in the article.You may find that more than one lab applies however, each article must have at least one differing lab topic.(ie> do not find 4 articles that deal in principles of inheritance.)
- Make a hypothesis about what you have read in the article (3 pts.).Something that could be explored further.Remember hypotheses are many times phrased as an If, then statement.(ex: If I increase the light intensity then the plant will photosynthesize more.)Give the article some thought and apply what you learned to think about what might be the next step or level in the research.
