Current events for ALL Classes!

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 one/two months. Videos should not be older than 2 years. 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?

biology Density of water lab

Measurement Lab

Title:  Hint, be descriptive and to the point

Question:  How can OHS measuring devices be used by students to accurately measure the density of water?

Hypothesis:  Hint, your answer must include the independent and dependent variables you will test to support or refute your question.

Test:  Hint:  Density = Mass/Volume.

Materials:
(1) P-200 micropipette, (1) P-1000 micropipette, (3) Reaction tubes, box of blue tips, box of yellow tips (1) 1000mL plastic waste beaker, (1) metric balance, supply of dH20 in (1) small glass beaker, paper towels, safety equipment-eyewear and aprons…….

ProceduresHints, Make sure your final procedures include labeled diagrams
  1. for the Rd just do your best to describe how to use each material in a logical order  
  2. for a diagram show how the P-1000/ P-200  window will read for each different volume extraction and how you will use the balance.
  3. you will conduct at least of 3 trials of data collection for each member of your group
  4. you will need to empty reaction tubes of any trace of water and re use-them between trials.

Data Table: 

(example:  Remember that you need room for at least 9 trials!!)

Measurer
Mass of empty tube
Mass of tube and H2O
Mass of H2O
Volume of H2O
Calculated H2O density







DON’T forget to record observations of data collection.

Analysis: 
This section should include a graph of the data (mass on the y-axis & volume on the x-axis), the formula for density, show at least one example of the math you did when calculating density and answer the following questions. Hint you will want to convert measured μL – mL to answer the questions
  1. Check your accuracy for the measurement lab; calculate percent error for the average of your three trials?  

Percent error = (measured average density – 1g/ml)  . 100%
                1g/ml

  1. What is the accuracy for the average of all trials by your group?
  2. Which measuring device is most accurate?  Explain your answer

Conclusion:

Don’t forget to explain what happened?  Restate your question and hypothesis and why you thought it was the best guess.  What do you know about the answer to the question?  How does the data support your answers? i.e.use numeric comparisons to support your answers!  How did human error influence your data?  How could you further/redo this experiment for more accurate results?  What is the social context for this lab? (This should be at least 3 paragraphs)

bioloiogy big mouth guide sheet

Purpose:  You are to figure out who has the biggest mouth in class.

Question :Who has the larger oral cavity, males or females?

Hypothesis:  (You give)

Test: We will fill the mouths of volunteers with water to get an approximate volume of their oral cavity.  We will do this multiple times and take an average so that we can compare class data.  We will then determine whose mouth is “the biggest”, boys or girls.  We will also measure the height of all participants, in meters.

Materials/table
·       2 cups *Note NO LIQUID, CONTAMINATED WITH SALIVA, MAY GO INTO THE GRADUATED CYLINDERS!
·       100 ml Graduated cylinder
·       Pen or pencil
·       marker
·       Water *Note ALL SPILLS MUST BE CLEANED BEFORE ANYONE
LEAVES TODAY!
·       Waste water disposal-1000 ml plastic beaker
·       Paper towels
·       Pipette (eye dropper)
·       Meter stick and metric ruler

Observational Journal:








Analysis:  SHow calculation examples made .  make 2 graphs :  bar graph of test subjects vs. volume in ml, line/scatter graph of test subject height in m (on X axis) vs. Mouth volume in ml ( on Y axis).
Discuss sources and effects of error

Conclusion: ( in paragraph form) Restate hypothesis, was it supported by experiment ?  did you answer your question? Support or refute with data.  Give a next step for taking this experiment further
