Birds Getting Smaller as Temperature WarmsA study of over 100 species of birds has shown that many are getting smaller and lighter, and climate change is believed to be behind the shift.
1. The first step is to look over the, "In the News," article, reading what you can without struggling.
2. Highlight or circle or underline or list on separate paper (or computer file) the words you do not know, or, do not know in this context, or just happen to like. Let's just pick some for example, though you may be familiar with all these words:
Birds Getting Smaller as Temperature WarmsA study of over 100 species of birds has shown that many are getting smaller and lighter, and climate change is believed to be behind the shift. According to Bergmann's rule, a biological principle formulated in the mid-19th century, animals tend to become smaller in warmer climates. Data collected in Pennsylvania between 1961 and 2007 indicate that many species of North American birds, mostly songbirds, are obeying this rule and gradually becoming smaller. Though the birds themselves are getting smaller, their populations appear to be unharmed. More ... Discuss
3. Define the words. Note: At the bottom of the blog, there are links to several dictionaries. You can also search for definitions of words in a search engine (For example, Google). Of course, you can also use dictionaries (as books). Remember to note down all the information you need to reference the definition's source.
- In biology, a species is: a taxonomic rank (the basic rank of biological classification) or a unit at that rank (in which case the plural is "species". This is sometimes abbreviated: "spec." or "sp." singular, or "spp." plural). [A] common definition is that of a group of organisms capable of interbreeding and producing [...] fertile offspring of both genders, and separated from other such groups with which interbreeding does not (normally) happen. Other definitions may focus on similarity of DNA or morphology. [S]pecies [may be] subdivided into subspecies[.]
- (Source: http://en.wikipedia.org/wiki/Species. Accessed 3-16-2010.)
- climate change
- Bergmann's Rule
- It's [...] a matter of basic physics that the larger a sphere, the less is its surface area relative to its total volume. Therefore, large balls lose heat more slowly, relative to their size, than small ones. You might guess, then, that animals tend to be larger in cold areas than in tropical ones. In fact, Bergmann's Rule asserts that geographic races of a species possessing smaller body size are found in the warmer parts of the range, and races of larger body size in cooler parts
- (Source: http://www. backyardnature.net/ecorules.htm; Accessed 3-16-2010.) [ Note from Dr-J: An elementary school student might be able to work this rule, Bergmann's, into a very nice experiment for a science fair.]
A rule or law concerning the functioning of natural phenomena or mechanical processes (Source: http://www.thefreedictionary.com/principle; Accessed 3-16-2010.)
A population is ...[a]... group of organisms usually of the same species, occupying a defined area during a specific time.
- (Source: http://www.rw.ttu.edu/2301_phillips/studentnotes/CHAP5_OH.htm; Accessed 3-16-2010.)
5. Re-read the passage again once the words you've selected are defined.
6. Next, read a few more general publications like tests, newspaper articles, and magazines that are not, "original source."
7. Then, search in the technical literature (where you will find original source laboratory reports). You might start by searching for birds and Bergmann's Rule.
- We find, http://www.pnas.org/content/105/36/13492, an editorial, more key words, and a scientist contact. At 10.1073/pnas.0800999105 PNAS September 9, 2008 vol. 105 no. 36 13492-13496, "Ecological responses to on-going climate change are numerous, diverse, and taxonomically widespread. However, with one exception, the relative roles of phenotypic plasticity and microevolution as mechanisms in explaining these responses are largely unknown. Several recent studies have uncovered evidence for temporal declines in mean body sizes of birds and mammals, and these responses have been interpreted as evidence for microevolution in the context of Bergmann's rule—an ecogeographic rule predicting an inverse correlation between temperature and mean body size in endothermic animals." That's a great start, but, we haven't found, "lab reports," yet.
- Let's keep looking. But there are more tasks to do: Oh, yes, there are more vocabulary words to check on... I've gone ahead and indicated them in orange-red. As we Reach Read TM, we will discover more and more words. Like finding treasure in a computer game, these words hold the secrets to great discovery and winning! Now, back to our search.
- Gardner, J. L., R. Heinsohn, and L. Joseph. Shifting latitudinal clines in avian body size correlate with global warming in Australian passerinesProc R Soc B 2009 276:3845- lpage">3852, is one we can check.

Because the box for, "This Day in History," changes every day, a quote is provided below:
First Patient Successfully Treated with Penicillin (1942)Penicillin was the first antibiotic agent successfully used to treat bacterial infections in humans. Penicillin's effect on bacteria was first observed by biologist Alexander Fleming in 1928, but it was not until 1941 that scientists purified the substance and established that it was both effective in fighting infectious organisms and not toxic to humans. The first successful treatment occurred the next year. Where did scientists find the mold that allowed them to mass produce the drug?Source: http://encyclopedia.thefreedictionary.com/penicillin; Accessed 14 March 2010
I remember taking penicillin pills about the size of a pin head when I was small and had ear infections. They tasted so terrible...two small pills. Even buried in a, "spoonful of sugar," those penicillin pills tasted so badly. Just thinking about that taste is enough to cause me to grimace. If you had penicillin pills around the same time, you know what I mean!
My mother explained to me at that time that people used to die from ear infections if the infection spread to the nearby brain, and, how penicillin was a miracle for all the lives it saved.
How far we have come since the day in March 1942 when a patient was first treated with penicillin! Now we need to be reminded to use soap and water (and not antibiotic-based soaps and dish detergents). We need to be reminded what putting antibiotics into our cows and chickens does to our ability to get rid of infections. We don't want to get germs resistant to all of the drugs we have available and go back to the days when an ear infection was life-threatening. Therefore, it is a good idea to understand some of the underling biology.
First there is the idea that some, "germs," are...good. Can you believe it? Yes, good. Your body has on it (and in it) populations of bacteria. In fact, you can think of it as a bit like a football field with teams (of germs) battling each other to win. The idea is that you want to have enough good germs to win the game (of life). Live cultures help: pickles, sauerkraut, yogurts, cheeses, all with live cultures...not sterilized and sealed in a can, jar, or bag. A healthy diet and sleep and exercise also help. So does washing your hands frequently with a bar soap and water. By the way, did you know that the foamy alcohol-based hand cleaners in hospitals do not kill all the supergerms (VRE, C-diff, MRSA, etc.:That takes soap and water and sometimes chlorine bleach.)?
Second of all is the idea that we are organisms like germs are organisms. We have the same chemicals in our DNA, our genetic material, as the bacteria do. Hmmm! That means some things bad for them are bad for us, too! Lets use fungi for an example here. Do you know anyone with toenail fungus? It sure is hard to get rid of that organism without hurting the person, too. The pills for eliminating the fungus adversely affect the human. Liver and kidneys work overtime. Bacteria, too, share the same kind of DNA chemicals: the ones we need for life.
This brings us to the third and major point: To battle germs, we need to remember and use the concept of the unity and diversity of life. The unity comes about when we reflect on how the genetic chemicals the adenine, guanine, cytosine and thymine that link in A-T and G-C pairs to form, "the steps on the twisted ladder," that is the DNA molecule. This molecule is similar in all organisms, of course, each bearing its own sequence of nucleotide base pairs. That is the, "unity," of life part. We and bacteria use the same types of metabolism or body chemistry. Of course, you don't look like a bacterium, or for that matter, you don't look like a fungus, either. That is the diversity part. It is the play between the unity and diversity of life that enables us to use drugs like penicillin to get rid of the bacteria. For fungi, because their chemistry is closer to our own than bacterial chemistry is, it is harder to eliminate the fungi.
Let's look at drugs in our food and water supply. I can't do all the thinking for you. Use Reach Reading<^>TM<^> and get into the journal articles. Each of us needs to form our own opinions based on data, and then, we can inform public policy. In the United States, we can inform our Senators and Congressional Representatives. In other countries, use the mechanisms in place there. We can wash our hands with soap and water. We can eat kimchee, yogurt and other healty-bacteria laden foods. We must work together globally to stay ahead of, "bad germs," and enhance populations of, "good germs." Each of us has an important role to play. The reminder on penicillin in today's news item is a good place to start.

When a state park is made, people living on the land are uprooted. It feels terrible. Now, though, those people can truly feel they have saved a piece of the Earth. For example, Highland Park,
http://www.scotchtownhighlander.com/history/articles/highland.htm#_ftn5, on an Old Valley Central School bus route, displaced many families.
The wetland woods area is a touch of wilderness as the megalopolis that is Boston-New York-Washington-Miami has spread to, "Upstate," as that part of New York one-hour north of New York City is called. After nine-eleven events, so many moved from The City that farms costing 80K went up to 4 million as land parcels were rapidly gobbled up and farms and woods disappeared. The water table was adversely affected, too.
As macadam and cement replace wetland woods and farms in the Wallkill (kill = river; Dutch origin), flooding can occur. The State Park staying wild will alleviate damage to homes and businesses by protecting them from floods' worst damages. Extra water has a place to go. (Similarly, Boston's waterfront park on the Charles River, helps alleviate flooding.) Leaving the New York State park wild helps to alleviate the rampant temperate deforestation in the area.
Sometimes we like to pay attention to tropical deforestation, and, that devastation, but, we ignore the temperate devastation in our own neighborhoods. People in the tropics as well as the temperate regions see deforestation as, "progress." Jobs, money, and short-lived gains capture our minds...both in the tropics and in the temperate zones.
Education on wetlands and deforestation can help us realize the value of the park as it is. The trees and shrubs, the herbaceous plants, the microbes, the fungi, the animals...all organisms are a valuable part of our ecosystem. We need them. Keeping open spaces is a good deed. Thank you to those who gave up their homes and farms leading to the safekeeping of a treasure from our environment. (These people did not get mch money for their land,. The children had to change schools. Everything for them was uprooted. But, the treasure resulting from their sacrifice is phenomenal.)
Guido Dingerkus diligently tried very hard to preserve more lands as malls, hospitals (irradiation?) and businesses went up. He wrote many letters to the editor of the local paper (Guido was an active 4-H-er. He had a terrific insect collection. He knew how to handle snakes, even as a child. Guido published in Science (the journal) as a teenager. He knew fishes. He taught at the Sorbonne. Politics of saving lands became a passion for him. But, he can't be the only one.
Politics does overlap with science. We need to speak out to keep treasures of wilderness. The plants, fungi, and other organisms in wild areas hold hopes for new medicines, for example. Oxygen and water renew themselves in such areas, supporting life (including ours). Yes, we need the treasures of wilderness, plants and all. Please speak out on behalf of wilderness regions in your own areas. Like Guido, you might be the next, "Marjory Stoneman Douglas."

Sometimes people think America has tons of food so everyone should be healthy. What do you think? Rules governing the food supply differs in different countries. We have a lot of high frucose corn syrup in our food supply that in the 1970's wasn't there. Could there be a cause and effect situation?
I have done laboratories with students both at four-year colleges and community colleges in which students analyzed their own food intakes. The data from these analyses over 20 years shows the same trend as the, "In the News," article shows today. But at the community college, there are many recent immigrants, and their data is different than the average data acquired. Students from Ethiopia, for example, ate very little ate very little when compared to the other students, yet, the nutrients they acquired were at a low level but where there were no deficiencies. Students who had grown up in the Northeastern USA, however, typically showed very high values of some nutrients and below survival levels of others. The high values were typical of things causing diabetes, heart disease, obesity among others. The low levels were in nutrients affecting fertility and mood.
Students valued this experiment. They could compare there, "before" data to their, "after" data, after learning some nutrition. They could compare how they ate now to a diet they wanted to go on. They could compare what swapping junk food for fruit would do. In essence they could be the scientist and design the experiment. This exercise engaged many students in further pursuit of science, rather than stiooing with the one, "terminal" science course required of non-majors in biological sciences. (Such courses are called, "terminal," because many students stop their science education with the required course, It benefits society if students learn to ant to keep up with science, or, at least appreciate spending their tax dollars on research.) Some became science majors, but, many took two more science courses. Others took no more, but, at least now liked science and understood the value of good experimental design. The students were adults and the treatments were still regular foods that they would have eaten anyway.
Science literacy is helped by discussing current events like this with students. It is news that affects them. It can lead to more in-depth science reading if students are deeply interested. Can you get into the journal articles?
1. There was a typographical error when first posting this article that is funny. I'd like to share it with you:
The title is, "Think before Snacking...Look at all the research being done...," but, with the typographical error it was,
Thin before Snacking...Look at all the research being done...
2. The, "In the News," story was based on http://www.reuters.com/article/idUSTRE6210HC20100302, a story about science in Reuters which mentions researchers Piemas and Popkin. I did not yet find a journal article by Piemas and Popkin, the researchers mentioned in the Reuters article. It doesn't mean it's not there, but, I didn't find the research mentioned published yet. I put a link to Popkin. I did not find Piemas. http://www.cdc.gov/about/leadership/leaders/Frieden.htm is a post linking to Dr Frieden at the CDC, also mentioned in the Reuters news story.

Herbicide Turns Male Frogs Female A common weed killer known as atrazine causes chemical castration in frogs and can even turn some into females. Researchers found that long-term exposure to low levels of atrazine emasculated three-quarters of male laboratory frogs, while ninety percent of the study subjects exhibited low testosterone levels, decreased breeding gland size, feminized laryngeal development, suppressed mating behavior, reduced sperm production, and decreased fertility. Furthermore, the remaining 10 percent actually turned into females that were able to copulate with males and produce eggs. Because the parents were both genetically male, all the larvae produced by those eggs were also male. More ... Discuss
Why did I say, "The unity and diversity of life is an important basic concept on which to reflect when reading an article such as this one on the pesticide, "atrazine," and its effects on frogs?"
For the, "unity," part...DNA in frogs and DNA in humans is still DNA. Well, despite the, "diversity," part, similar DNA means many biochemical processes, including those of the endocrine system(s), are also similar. What does this similarity mean about public policy suggestions and laws when it comes to atrazine and other chemicals (like those found in some plastics) that interact with endocrine systems of organisms? What do you think?
Dogs on golf fields, turtles, now frogs...humans? Reflect. Use Reach ReadingTM to get into the technical literature on this topic.
This topic of changing gender can be confusing to children. After all, it is for adults, so, caution is advised in presenting this to young people if you elect to do so. The blog is for adults though and is on science literacy. Adults can stretch and reflect and stretch some more. And we need to in order to interact with our governments well about technical and scientific issues. We need to know things about the effects of chemicals found in pesticides and plastics.

While I was a graduate student, I had the opportunity to work as a tech writer for Sea Data, and, later, after getting my doctorate, as an electrochemical engineer. It was in the, "tech writer," stage that I learned so much about tsunamis. It was then that I got to use my, Modern Math," skills. In a way, you could say, "Modern Math helped save thousands of lives!"
For now, back to fourth grade, Mrs. Degnan, Montgomery Elementary School in the Valley Central School District, and modern math. First, Mrs. Degnan: What a wonderful teacher. We made rocket ships, we did base 2, base 8, base 10 and base 16. We built things, for example, I built a slide projector using a wooden box and an empty roll from toilet paper, and, oh, yes, the lenses. What a great year. And, we lucked out, we got her another year, too. Thank you, Mrs Degnan. Many of us went on in math, science and engineering. We all benefited from your teaching. It was your math that got me through high school and college... (My algebra teacher in high school had failed algebra in college... Fortunately, we learned algebra and Boolean algebra from Mrs. Degnan. So many lives saved.
Win Hill (Read his book and you'll see what I mean) can take the very technical and simplify it. George Kontopidis can do the impossible. Both are math and electrical engineering wizards. But, there is only so much time for the CEO and chief engineer of a company to do things. They were so busy at that time. Countries were ordering hundreds of wave and tide recorders from Sea Data. The technology stayed cutting edge, so technical instrumentation manuals had to be written. That's where I came in. I'd get to look at a new instrument, for about only five minutes, minutes before it was shipped out. Then, I'd be handed the schematic. I'd decipher the schematic because there wasn't another instrument to look at. Four days later, there was the manual, all done. When the work needed to be done, it needed to be done yesterday, as they say. (And, this was in the days that I had to put in a hard drive and take it out in order to word process different projects. It was also in the days when turning on a saw in the other room to make shipping crates to send the instruments out in (which of course, like the manuals, were needed, "now!") meant that the computer would crash. I learned to save after every half-sentence because computers did not back things up automatically the way many of them do now.
Let's see: Back to math class. We could multiply and divide in binary, hex, and so on. I used to be able to do bases 2, 8, and 16, faster than base 10 (which is probably why, "Modern Math," is often picked on: We need those times tables.). I never forgot those skills.
To interpret the data from the wave and tide recorders, base 2 was needed...binary. I was able to easily write and explain the math needed. I could do the math. Customers buying the instruments finally could teach others that needed to use the units how they worked. The manuals contributed to increased sales.
But, the bottom line is not money in this case, but, the lives saved. Thanks, Win, George, and Mrs. Degnan.
You see, grade school studies and high school studies may not always seem, "important," or, "relevant," but using them as a critical thinker, you can solve world problems. You never know, you might even save lives.
That reminds me of a joke...
There are 10 kinds of people in the world. Those that understand binary and those that don't.
Sometimes you'll see that on a T-shirt, but, Matt Baum (personal communication) is the person that shared it with me.
I hope you enjoyed this tsunami story.
You might ask how a botanist got to do so much electrochemical engineering. Remember that I am an electrophysiologist who did a botanical study following a mycological study. I will say if I got the same degree in the electrical engineering department my stipend would have been 2 to 4 times higher, and my salaries, too! Cells are found in living organisms. They consist of a salty solution, some membranes and some organelles. I'm sure, you have learned all the parts of prokaryotic and eukaryotic cells. Well, chemicals in the cells often have charges, thus, electrochemistry: a kind of combination of biochemistry and electrical engineering. Did you know plants are so much fun? Sometimes botanists are under-rated. Chromotography---that chemists rely on...invented by a botanist; Brownian movement, on which Einstein based some of his work... discovered by a botanist. I interfaced an old navy oscilloscope to a three-electrode system and later to a computer (before you could buy these instruments already integrated with computers as systems or as instruments with built in computers). I looked at environmental stimuli, like acid rain, or, light, or biochemical stimuli, like fungal toxins, and their effects on elm membrane potential. Thus, electrical engineering, computer and instrument design, botany, forest pathology and mycology all fit into a nice package together, as long as you've got the math. (That's where the science literacy (which needs math literacy) comes in.

Here's an example on, "glycemic index:"
When you have, "a need to know," hard words won't stop you. Even if you can't read the article, you can carry it in to your doctors' offices as your own, "reading material," and have a positive effect on your health care (my opinion and experience).
Now, back to the example of, "glycemic index." Let's look at the author and title of the above-referenced journal article:
Endocrinology Vol. 142, No. 3 1148-1155

Monounsaturated Fatty Acid Diets Improve Glycemic Tolerance through Increased Secretion of Glucagon-Like Peptide-11

Hmm! What words do you know in the title?
Do you have them all on your list? Congratulations! Now for the rest of us...
Take it slowly, like Einstein did when he read. It's ok to take a long time, even to get through the title. Oh, by the way, science fair people, it is a good idea to support some of your work, in background information or in discussion, by citing journal articles, so, take your time. You can do it. (Do I sound like a cheerleader yet?) Ah! That is more like it. relax. You are not supposed to know all the words. In fact,
No one knows all the words.Source: Joan Beinetti, Reading Specialist and Home School Expert; Personal Communication with J. S. Shipman; 1989.
Don't you feel better knowing that, "No one knows all the words." Even geniuses use dictionaries. You don't have to be afraid of science any more (if you ever were.)
That release felt grand, didn't it. You don't have to be afraid in front of students of needing to look up words. It is expected!!! They should expect it of themselves. You are, "modeling," that desired behavior while learning new vocabulary yourself.
After slugging through the first article, the rest get easier and easier. Note, I didn't say easy. But after about five articles, they may seem easy to you. And, you will know a lot about your disease.
"Glycemic index," isn't a disease," you say.
"I know that," I reply. So, let's get on with the matter at hand. People with diabetes, pre-diabetes, people who are hungry all the time, people who drink a lot of water (more than everyone else), people who are hypoglycemic, people who are obese, people who are sooo slim, people who are, "just right," ...many people have diseases related to the, "glycemic index."

DURANT, Okla. – Five Fish and Wildlife students from Southeastern Oklahoma State University attended the joint meeting of the Arkansas and Oklahoma Chapters of the American Fisheries Society recently in Fort Smith, Arkansas.
All five students gave presentations (co-authored by Dr. Tim Patton, professor in the Department of Biological Sciences), including three oral presentations and two poster presentations.
Joseph McAllister won the best student paper award and one of two $1,000 scholarships awarded by the Oklahoma Chapter of AFS. Notable was that McAllister won the best paper award and the scholarship in competition primarily with graduate students. He is a senior and a graduate of Choctaw High School.

For over a decade, the National Science Education Standards have focused our attention on scientific literacy, a golden umbrella that encompasses not just reading, writing, and speaking but the attitudes, content knowledge, and process skills that make it possible to investigate natural phenomena and understand the results.Source: http://www.nsta.org/publications/ostb/ostb2008.aspx; Accessed 2 Mar 2010.
In the same way basic literacy involves knowing how to use a dictionary or an index, science literacy involves knowing how to find information on science topics (health, botany, engineering, among others) that is worth reading. One can find so much information on the internet. Look at the variety of search engines:
- MSN MSN Germany MSN United Kingdom MSN Canada MSN Spain MSN Italy MSN France MSN Austria MSN Switzerland
- Excite Excite UK
- Google Google Germany Google Azerbaijan Google United Kingdom Google Canada Google Spain Google Italy Google Japan Google Russia Google France Google Austria Google Switzerland Google Poland Google India
- National Directory
- Web Crawler
- Web Top
- Web Wombat
- Ask Jeeves
- Find What
How can you tell valuable information from , "hype?"
The jury is likely still out on these questions. I try different search engines and usually find what I want most rapidly on Google. I like to find original source material whatever source engine I use. How about you? What search engine(s) do you use? Why? What kinds of responses do you get? Post comments below, or, e-mail me a post and I will post it for readers and link it here. Happy researching!
Let's try some experimenting...
Let's look for science literacy and internet use on the different search engines... (look for original source material).
Google's response starts with:
Let's try Altavista's top three:
eHealth literacy: essential skills for consumer health in … - Norman - Cited by 55
… literacy in science and engineering undergraduate … - Leckie - Cited by 81
Intrinsic and extrinsic motivation in Internet usage - Teo - Cited by 364

Science NetLinks provides a wealth of resources for K-12 science educators to provide standards-based Internet experiences for students.
Now, you can compare and contrast these two search engines, and try some others.
Unless you want students to look at the top posts, which are determined by how people who know how to post (o their work shows on the top of the list (...and, may not be the best choice...), you have to show better ways of searching. How? By, now here's a place to use Modern Math that often gets picked on (but is actually very useful to me): Use the Boolean Algebra learned in elementary school during the, "Modern Math," period: AND, OR, NOT... Some visionary(ies) saw to teach Boolean Algebra because he, she, or they could see the, "Computer Age," coming.
I had to put some good points in on, "Modern Math," because it has been so helpful to me and it seems to, "get a bad rap," much of the time. But, let me get back to the use of Boolean Algebra for searching the internet. (Math is so important to science literacy.)
In our example:
Science literacy and internet use
Science literacy AND internet use
Science literacy OR internet use
"science literacy" AND "internet use"
"science literacy" AND "internet use" AND (elementary OR K-6)
Try a few different ways of searching and you will get the idea. Are you finding differences?
Using this one:
"science literacy" AND "internet use" AND (elementary OR K-6)brought up something on target, right away (But, so did the AltaVista search---which perhaps anticipated the search string a person meant to use...):
Understanding how young people evaluate information on the internet.
In the recent session on games and learning, Jonathan Fanton reported that one goal of the Macarthur digital media and learning initiative is to better understand how young people evaluate information that they find on the internet. In our work on Science.net, an epistemic game in which middle schoolers spend several weeks role-playing as science journalists and writing several stories for an online newsmagazine, we have found that our reporters begin the game feeling comfortable with the internet. They tell us about using web sources for school reports, for chatting, for playing games with their friends. They even report knowing that anyone with a webpage can publish opinions for the world to see.
The majority of them, however, don?t have a strategy for assessing the reliability of the information that they find. Here?s one typical pre-game interview response: ?You never know, it?s the internet. If it?s like the first thing that pops up and then it looks pretty professional, then I?d use it…?

If you (and your school) are interested in participating in a study on Reach ReadingTM AND/OR on Critical Thinking AND/OR Science Literacy, please e-mail me: shipmanjs at g mail dot com. (I hope you smiled at the AND/OR references).
I think I will do a post on Tsunamis and the role of Boolean Algebra (AND Modern Math) in saving lives. I can tell much of this information first hand.
