A little history of science info: In 1977, the last natural case of smallpox was discovered in Merca district, Somalia. The World Health Organization considers Smallpox to have been eliminated by vaccination, a spectacular success.  Later this year, both 6th graders and 7th graders will study some infectious diseases.

homework for tonight:
7th graders: none
6th graders: study for test tomorrow; short review sheet passed out in class today. Review the long form study guide answered in class today.  NOTE: when determining volume, remember you have two methods:
1. Measurement and Calculation: use this with a regular solid of any size.  For a rectangular solid, measure and then multiply: V = L x W x H.  Other regular shapes have different formulas.  Ex: volume of a cylinder V =  π x r x H, where  π is read as Pi.

2.  Water Displacement - if the shape is irregular, dip it in water.  You start by measuring the starting volume, then dip your irregular shape into liquid fo tind the final displacement. From final displacement, subtract the starting displacement.  The displacement (difference between final volume minus intitial volume) is equal to the volume of the solid.

Tuesday Homework

Homework for tonight:
Would you rather eat like a snake, like a lizard, or with teeth?  Or would you prefer to eat like a chicken (you know that word Paleolithic-"Old Stone Age"- that you learned in social studies in 6th Grade?  Look up gastrolith).

7th Graders: As a reflection, design an experiment on digestion.  Use the same materials that we used in class today.  Figure out how to change the experiment to focus on a certain idea of yours.

6th graders: complete calculations of density from the lab; and write at least a one-sentence reflection on what you've learned about density.

Weekend

No homework for the weekend.  Sixth graders can complete their worksheet "Volume by Water Displacement" if not already done; this page is due on Tuesday.  Also, they have a Study Guide, for a test in the next week or so, which they can start answering.. 

Seventh Graders: no homework.  We'll continue with our activity on internal anatomy on Monday.

One of my favorite holidays is Global Handwashing Day on October 15. Why? In our country, not washing your hands can lead to getting sick.  In other parts of the world, many diseases spread by poor sanitation, such as inadequate handwashing, lead to diarrhea that contributes to  one in every five child deaths, around 1.5 million a year. That's over 4,100 children dying every day!  Take a look at : Lather Up for Global Handwashing Day, Posted on: October 14, 2011 8:00 AM, by The Pump Handle.  Author: Jay Graham.

Scientists in Great Britain examined thousands of cell phones and hands, They found that, depending on location, between 16% and 44% of the phones and hands were contaminated with e.coli bacteria indicating the presence of fecal matter.  'Fecal matter' is the nice adult way of saying 'poop'.   (Now Wash Your Hands - And Your Mobile, Fergus Walsh, BBC News, 10/13/11 at http://www.bbc.co.uk/news/health-15284501Hand washing is the most effective and economical means of stopping bacterial and viral infections.


So wash your hands!

While studying the water cycle, Andrew and Davidson want to know if adding energy (light) will make water evaporate faster. They each put 250 mL of water in four 500-mL beakers, and place beakers around the lab, some near the sunny windows, some near the drafty windows around the air conditioner, some on top of the air vents, and some in the dark closet. Andrew and Davidson checked and recorded the amount of water left in each beaker every day for 3 weeks.


8. How could Andrew and Davidson write their hypothesis?
     a. Water evaporates more quickly if exposed to sunlight.
     b. Water in a cool place will evaporate more quickly.
     c. Water in a cool, dark place will turn cloudy.
     d. Air from vents passing over the beaker will cool the water and make it evaporate less quickly.

9. Which of the following were not variables in Andrew and Davidson’s experiment?
     a. The amount of water
     b. Size of the beakers
     c. Exposure to light
     d. Using tap water or bottled water

10. In Andrew and Davidson’s experiment, which of the following factors were kept constant?
     a. The amount of water in the beakers
     b. Exposure to light
     c. Using tap water or bottled water
     d. None of the above

11. Did this experiment include a control, or not? __________Explain your answer with evidence.



Andrew and Davidson recorded the following data:
    a. water near the sunny windows decreased by 30 mLs per day, and was gone in 9 days.
    b. water near the drafty windows around the air conditioner decreased by 25 mLs per day, and was gone in  10 days.
    c. water on top of the air vents decreased by 40 mLs per day, and was gone in 7 days.
    d. water in the dark closet decreased by 15 mLs per day, and was gone in 17 days.



12. Make a data table using Andrew and Davidson’s recorded data.






13. Draw a conclusion: did putting energy (light) into the water make it evaporate most quickly? _______ Explain, using evidence from your data table.





14. How could Andrew and Davidson confirm their results?
     a. Fewer trials
     b. More trials
     c. Smaller sample size

15. Risk vs. advantage: Medicines, like the simulation (lemonades) we tested, involve taking on a risk in exchange for gaining a possible advantage(cure or relief of symptoms). For example, Dr. Goldberger’s prisoners took risks (getting pellagra) and gave up advantages (possibly avoiding the disease) to gain an advantage (better diet for some, early release). Taking on risk and giving up something to get something else is a _____________.

16. Vocabulary words (Write in the definitions):

clinical trial -

Control group -

data -

disease-

dominant - usually the hand that you write with.

Ethics

Evidence -

experimental group -

hypothesis -

Inference -

informed consent-

Observation -

placebo

placebo effect-

qualitative -

quantitative -

range

reproducible - able to be recreated and repeated.

sample size -

sensitivity - how much an organism or part will respond to stimulation.

simulate (simulation) -.

trade-offs

variable - any factor that could affect the results of an experiment.
Experiments should be designed to allow only one factor to change,
so we can see how it affects the result. Ex: Dr. Goldberger reduced
variables by limiting prisoners to a diet of corn until many of them
developed pellagra.
