all classes Current event extra credit oppurtunity

ALL classes: Current events e.c.

You will choose an article or science related video of over 2 pages or 45 minutes on science current event. It will fall into one (or more) of these categories:

·         Scientific discovery – for example, scientists find comets may have delivered the water found in earth’s oceans.

·         Science-related event – for example, the Japan earthquake/tsunami/nuclear plant meltdown; the launch of a space probe.

·         A cultural change/happening that involves science/technology – for example, bicyclists’ clothing that can act as a radar gun to show drivers how fast they’re moving.

·         Science in public policy – for example, a bill or law that deals with science (cap on carbon emissions).

The article must be timely, meaning it’s been published within the past six months or 3 yrs. for videos. Finally, technology articles are okay, but I will not accept any product announcements or reviews.

Create a write-up of your current event, summarizing the story and answering key questions. You will include a copy of the story you are citing or the golden page format for the video, movie or program.  

Science current events will:

Cite the news source, using the Oceana Golden page format for citations found on the Oceana website. Magazine Article:

Perlman, Jeff. “Sultan of Swat.” Sports Illustrated. 12 February 2001: 54-59.

Newspaper Article:

*  Taylor, Michael. “Potholes Scar Roads Across Region.” San Francisco Chronicle. 23 October 2005:

*  Give the title of the article, author’s name, and article date within the body of the summary.

*  Summarize the event in your own words, using complete sentences. Spelling and grammar count.

*  Your summary will answer the following questions:

·         Who/what is the subject of the story?

·         Where did it happen?

·         When did it happen?

·         How did it happen?

·         Why did the event happen, or why was the event important enough to make the news?

·         Why did you choose this article?

·         What did you learn from the article, and what are your thoughts about this event/issue?

*CONNECTION AND COMMENT RELATED TO ONE ESSENTIAL QUESTION:

·         How does this event affect the world or region where it occurred?

·         How does this discovery advance science?

·         What does the discovery/event mean for our society?

·         What does this discovery/event mean for future work/the environment/humanity/etc.?

·         If the story is about a law or policy, how does the policy or law affect science/society?

Physical Science HW 10/23/15

1)  Finish final Lab write up for Drops of water on a Penny.

Analysis:      What is your average number of drops? Show an example of how you calculated the average  # of drops for the trials you did. Create a data table showing the average drop # for your group. Make a bar graph of your trails and the average # of drops.

Conclusion:             This should be in paragraph form and not just answers to the following questions

Prompts: Did you answer the question?   Do your results compare to the other tables?  Explain.  How might error have occurred in your experiment?  How can you redo your experiment to attain more accurate results?

Bonus Points:  if you finish early, you may earn bonus points for conducting a next step to this experiment.  You are limited to the materials provided on your person & you must make another lab write up.  You may also include a graph.


2)  Read and Take Cornell notes for Skills handbook pgs. 931 - 938 on measurement and organizing information.

Biology HW 10/21/15

Physical Science HW 10/20/15

1) Read and take Cornell notes for Student Skills handbook pgs. 924 -930 in the Glencoe Earth science Text .

create RD (rough draft ) for Drops on a penny lab.  Have Question thru Data sections ready to get OK'ed to go into lab.

Instructions:  DO NOT WRITE ON THIS HAND OUT!  You and your group mates will be practicing the steps of the scientific method, conducting an experiment and writing-up a lab. 

·        On a separate sheet of paper (NOT in the notebook) write the names of the members of your table that actively help with all parts of the mini-lab; this will be your lab write-up.

·        Write out the question given to you below, include the label Question:

·        Write out Hypothesis: and then your educated answer to answer the question.  Remember to discuss with your tablemates about how to make an educated guess then record the hypothesis on your lab write-up.

·        Continue writing the label for each step (Q, H, M, P, D & C) and following the hints for each step.

Question:  How many drops of water can a penny hold?

Hypothesis:  What is your educated guess to answer the question?  You may compare a penny next to a single drop to help you with this.

Materials:  Record every item used for data collection

Procedures: Record Step by step directions of how you used each material listed in your experiment to find your answer, include diagrams that help illustrate complex procedures. Final procedures should be more complex than those listed in your RD.

Data table:  Have room to include fifteen+ trials of data collection.  Yes, do the experiment at least fifteen times, (5 trails per person) make sure everyone in your group has an opportunity to collect data by doing the experiment.

Analysis:      What is your average number of drops? Show an example of how you calculated the average  # of drops for the trials you did. Create a data table showing the average drop # for your group. Make a bar graph of your trails and the average # of drops.

Conclusion:             This should be in paragraph form and not just answers to the following questions

Prompts: Did you answer the question?   Do your results compare to the other tables?  Explain.  How might error have occurred in your experiment?  How can you redo your experiment to attain more accurate results?

Bonus Points:  if you finish early, you may earn bonus points for conducting a next step to this experiment.  You are limited to the materials provided on your person & you must make another lab write up.  You may also include a graph of your data for e.c.
