Science Fair Participants

First: Congratulations to Elliott Rebello, winning his category in the Eleanor Roosevelt HS Science Fair.  (The reason I single him out -- he's my intern.  Be sure, though: the work he presented was his.  And it was his presentation and understanding that earned him his place.  Yay Elliott!)

Having judged another year's science fair at ERHS, I'll share some thoughts for participants.  I'm a little emboldened that maybe I know something since Elliott did well.  On the other hand, maybe he did well in spite of me.  Use your own judgement on what ideas to make use of, and how to make use of them.

One note: I never did very well in science fairs when I was growing up.  You don't have to do well in science fairs to do well in science, even more true than you don't have to be good at math to do well in science.  One failing in most of my projects: I was setting about learning what was already known, rather than striking out my own path.  This is an excellent way to learn more, but not to get science fair points.

My base suggestion for any age: try to learn more about the universe, know what you did and why you did it.  Maybe there are points in it, maybe not.  But you'll definitely learn something, which is always good.

For science fairs, the major categories on the official judge's score sheet are: 'Scientific Thought', 'Creative Ability', 'Thoroughness/Clarity', and 'Exhibit Presentation'.  They have some connection to usual professional proposal or paper review criteria (except, mostly, for exhibit presentation).
But we all, and it's interesting that it's all of us given that we come from different backgrounds, even judges in my rather small niche, think differently than this.  We start more like journalists:
  • What did you do?
  • Why did you do it?
  • Why did you do it this way?
  • What did you learn?
  • How would you do it differently?  (given what you've learned)
If you're doing ok at this level, we get more detailed.  But a little explanation of these questions and what we (or at least, what I) look for.  'What did you do' should be a no-brainer for you.  Your challenge is to keep the answer fairly brief, a couple of sentences.  I didn't really learn this until graduate school, when one of my graduate advisors really challenged me.  Very difficult to condense my previous 3 years of work in to 1 sentence.  All those wonderful things I did, for wonderful reasons, and he wanted 1 sentence!  Turns out there's a purpose to this.  Namely, it gives us a very quick starting point for what we're looking at and what kinds of more detailed questions we'll be needing to ask (or checking that you answer in your set piece presentation).

The other side is of the what did you do and why did you do it is -- we like to see some enthusiasm from you for your project.  This can be replaced by acting, if you're a good enough actor, but you probably won't carry out the rest well if you're planning on being an actor.  The rest includes some real thinking and work.  The person who's interested in what they're doing will fill these in appropriately. 

'why did you do it' is a slightly different issue.  There are thousands of ways to investigate the things that you looked in to.  The 'what' gives us the concrete.  The 'why' is where you have the chance to talk about how your project fits in to the larger scheme of doing science -- learning about how the universe works.  The project you do will enable you to do or understand ... well, something.  This is partly addressed in the 'future research', but not really.  It's easy to say what else could be done.  More interesting to us is what's interesting to you about how to follow on.  This is a step in some direction of you understanding the universe, what direction is interesting to you from here?

'why did you do it this way' comes to the tough part of your what you did and how you did it.  Given the thousands (millions?) of ways that your part of the universe could be studied, why did you choose this method?  Maybe it is that this is the only route that you had data for.  That's fine, just say so.  If this the why, it's a good place to mention what you'd do if you had access to some different kind of data that might exist in the future, or that would exist if you had -- more time, better equipment, different equipment, sibling didn't eat the peas you were growing+, ....

That's also where you're displaying your 'creative ability' points.  You're choosing what to do.  This is a creative act.  A hard line for mentors (me included!) is how much to tell the student what to do, and how much to let them figure things out themselves.  Your creative ability is where you're the one choosing what to do, or researching/understanding why the things you're doing (however you got that list) are better than the things you're not doing.

Knowing what you did and why you did it is huge.  Sequencing Neanderthal DNA can be great and interesting.  But if your answers are "I dumped stuff from vial a in to vial b and tossed the result in to a machine." and "Because my mentor said so."  you're going to 'lose' to the kid who snagged data from the web (and knows what it is and means) and analyzed it to see if she could predict something about radio reception on earth*. Whether you're successful in predicting the earth's radio reception doesn't matter -- you knew what you were doing and why.  We try tons of ideas in science, most of which don't work out.  If you're learning this at 14 rather than 34, you're much better off!

Non-digression: Some students had mentors, some did not.  You're not necessarily better off with a mentor than without.  Since one of the things we're judging for is your creativity, you might do better without a mentor telling you what to do.

What did you learn? is the standard conclusions kind of question.

What would you do differently? is where you show what you really learned.  One student today was apologetic about not including all sorts of data she discovered existed, but only after she'd turned in her project statement.  The important part to me as a judge wasn't whether she'd included all possible data -- nobody knows what that will turn out to be.  But that she recognized that some of it (not all) was relevant to the thing she was studying.  This happens all the time in science.  Being able to recognize it happening in your project is good.  Knowing how you'd incorporate it if you did the project again is even better.  Drawing your conclusions on the data you did have is paramount.

This is a subcategory of its own "The conclusion is justified based on the data and results." -- and one of the harder things to get used to in science.  You may be confident that something is true.  And you may be right (turn out to be right once more/better data are available).  But if you don't have the data, you've got to go -- for now -- with it not being true, or not being supported, etc..  Whatever conclusion the data do support.  In reviewing professional papers, I've occasionally been in the position of thinking that the authors were right, but having to say that they didn't have the data to support their conclusion.  This is a difficult point.

But, again, the main thing to me is to learn something.  It's a fun process, and maybe you get a point or three in science fair as well.


+ This didn't exactly happen, but sibling effects have factored in to a number of results over the years.  Consider avoiding this to be part of your creativity points for getting a good experiment done.  One of today's students did address the sibling factor++, and yay him.

* I haven't seen the Neanderthal example exactly, but close enough.  And the solar data project is not exactly what one of today's students did, but close enough for blog purposes.

++ I hope you got a laugh here.  But it's real.  Ocean buoy data gets contaminated by sea gulls perching on anemometers, algae growing on the temperature gauges, and fishing ships sweeping up the buoy along with fish.  Satellite data get contaminated by solar storms, sun glint off the ocean, micrometeors slamming in to the instruments, and so forth. Not siblings, but things which exist and have nothing to do with what you're trying to measure, yet affect your observations.  Dealing with these is important.

Science Fair Judges

I'll write about and to science fair judges before a note to the students.  A joke I made today got its due chuckle, but there's a real point to it.  I observed of judges that "We're very scary people."

Now, we know ourselves, and scientists in general are not scary people at all.  Even more so, if anything, those of us who do science fair judging.  We tend to be parents with school age kids ourselves, or at least not too long since we were (and, in my case, I'm still an uncle to kids this age).  And to like talking with kids and have a certain degree of understanding of (in today's case) 14-18 year olds. 

On the other hand, I can recall ages back, when I was a 26 year old finishing his PhD and presenting at an international scientific meeting.  Only about 200 people in the room (on the other hand: 200 people in the room!).  And I was 26 and nearly done with a PhD, not a 14-18 year old in perhaps my first talk with a scientist.  But I was seriously nervous, before, during, and after.  Most of that was unnecessary, as, again, scientists aren't actually a very scary bunch.  (It did work out in my accidental favor, more in a moment.) 

It was a great relief to survive the talk (nobody threw anything!  er, ok, that didn't happen to anyone, and I'd never seen it happen before.  But ... I was nervous).  And it was thrilling when, unforced, one of the 'Big Name in Field' people present said they'd liked my presentation.

I try to pass this along (not the big name in field aspect, which I'm not, but at least a good word somewhere).  And try to de-scarify for the students I talk to about their work.  We're still pretty scary to the students.  But I enjoyed my chats with students, and hope they came away with a bit more understanding of doing science.

The 'more in a moment':  The later postscript on my presentation was about my nerves.  Back then, when I was nervous, I spoke slower.  Opposite of most people, but it worked in my favor.  The thing was, at an international meeting, many people (in this case, about 2/3rds) are not native English speakers.  A speed that a nervous native is capable of racing through can be all but impossible for a non-native to follow.  Since I slowed down, I was more understandable to the group.  Several folks thanked me for my consideration.  They didn't know it was terror :-)

Undergraduate Opportunities from NASA and NSF

Last Monday was opportunities for high school, and by chance, today, I'll move up to college.  From one of my email lists:

National Center for Science Education now also defending science on climate change

The National Center for Science Education is now also engaging on teaching good science on climate change.  I've long been a member, because they've been for even longer helping ensure that science is taught in biology classes.  I'm not quick on the announcement, it was originally made on the 16th.  But if you haven't seen the mention yet, it's new to you :-)

I'll add a few thoughts of my own as a long-time member, and one who had suggested some time back to the director, Eugenie C. Scott, that they take this step.  One of the things I like about the NCSE is that their focus is on the science.  They're not the place to go if, say, you want someone to lobby for your idea for solving climate change.  They're a good place for parents, teachers, school boards, to go with questions and concerns about whether the science in your school's textbook is good, or is even science.  NCSE is also a good place to go to find out what is happening in your state regarding attempts to change the science curriculum away from science.  The main page address is http://ncse.com/

It was partly the tracking of attempts to remove teaching evolution in biology classes and other such anti-scientific moves that made me suggest also covering climate change science.  Increasingly, over the last 10 years, bills opposed to teaching good science in biology classrooms have been including directives opposed to teaching good science in earth science classrooms.  Bills to deny that CO2 is a greenhouse gas, or deny that there's a greenhouse effect, or to deny that CO2 is increasing and this is due to human activity, and other versions of denial.

Young scientists

In Knight anoles, you got to see part of the reason I made one of my goals for this blog to be inclusive of middle school students.  They can be quite interesting to listen to about science, and can learn quite a lot of it themselves.  Biased as I am in being a father and uncle, I still believe that kids other than mine can match, or at least approach :-) mine.

So I'll mention that if you're a teacher, parent, or a student yourself, and your kid/you write up a science essay, you're welcome to submit it here for consideration.  I'll look for the essay to teach me something about the science, and to show the love of learning about your topic that Kristen showed for hers.  As you might guess from my usual topics being climate and ice, but this note of Kristen's being lizards, you're not limited to my professional areas. 

There will be details to work out, maybe later we'd want to establish it independently of this blog.  But think of it as something in the vein of Journal of Young Scientists.  A chance to share your love of your topic with others.  You can send to me at bobg at radix dot net.  We'll play things by ear.  I've created the tag 'young scientists' and retro-applied it to Kristen's (first! :-) note.

Knight anoles and science writing

What Are Knight Anoles?

By: Kristen Martinet

Science/ Period 2

Abstract
Knight anoles are very interesting lizards. They are the largest anoles in the world and have very distinct features such as their speckled backs and striped sides. These reptiles are an invasive species in Florida and originate from Cuba. People like to keep knight anoles as pets, but then release them into the wild without knowing the consequences for the lizard. This makes them more abundant in urban areas. They eat insects and other lizards in the wild and in captivity. When fighting off a predator, the lizard bluffs to scare it away. While fighting with other males, the anole bobs its head up and down and extends the dewlap to look tough.  In the summer, knight anoles breed to create at least eight new baby knight anoles in five-seven weeks.     Knight anoles (anolis equestris) are a very interesting species of lizard that are also called the Cuban anole. This reptile is part of the order squamata, the sub-order iguanidae, and the family polychroidae. The knight anole is part of the genus anolis, which has about 250 species (Crowther, 1999). A researcher from Centralpets.com stated that the common name “knight” is derived from the Latin species name “equestris” which is derived from “equester,” a Latin word for knight. The other common name, Cuban anole, is probably used because its first home is in Cuba.


    This lizard is a very recognizable species. It is the largest anole in the world, so if any researcher was walking around in its territory, he/she would definitely notice. The knight anole is known as a “crown giant” because if its crested head. This also explains why it is called the “knight anole”-- because of the “helmet” on its head! This head is usually 7 inches (18 centimeters) long. That is a large percentage of its body! The whole body of a knight anole is 13-19.375 inches (33-49.2 centimeters) long. Its maximum snout-vent length is 188 millimeters of it massive head. (Wilson, 1997) Its eye is like any other anole’s eye, with a black and round pupil. The anole’s eye has a black spot around it, much like one on a domesticated dog. In its mouth, a knight anole houses an unusually bright orange tongue and extremely sharp teeth. I think that the tongue is used to scare off predators because of its bright color. Male anoles have an enormous pink throat fan below the lower jaw. Females do not have a throat fan. Going down from the head is a nape that has a small crest on it, which looks like a wrinkle on the knight anole’s skin. The body has yellow and/or white highlights on it between the body scales that look like plates of armor. The short legs make it relatively slow. Its feet have special pads that can cling to some surfaces, including trunks of trees.
They are mostly lime green with black, orange, and sometimes white speckles on the back. The speckles resemble sprinkled pepper on a lime. Yellow streaks are also seen on their sides. Their scales look a bit wrinkly, making any knight anole look like an old warrior. The skin can change color. Some people mistake the knight anole for a chameleon because of this, which makes me a bit annoyed. I think that many scientists seem to argue about the true maximum length of this lizard because they all know that there is always something bigger and better out in the environment.
    Knight anoles live in Florida and Cuba. They were introduced to Florida accidentally, probably by ship or airplane. Animals that come from one country to another are called invasive species. These lizards live all over Cuba where there is a tropical climate and shady trees. I like to imagine the knight anoles in their homeland, climbing up large and leafy trees to find shade so they can extend their dewlap in pleasure. In Florida, this reptile is becoming an established species because of its ability to adapt to new environments easily. The knight anole’s ability to adapt makes it able to colonize in natural areas as well as urban ones (Wilson, 1997). So far, the knight anole has occupied four of Florida’s counties, including Broward and Dade and somewhat into the Keys. It is also slowly fanning out into other southern states such as Georgia and Alabama. The knight anole has been found commonly in the shade trees along streets in urban areas such as Miami. Sadly, the knight anoles don’t usually survive Florida winters because the sudden drop of temperature is too much for their bodies. It is just like when you take a hot pot and put it into iced water; it shatters. Anoles live for 15 to 16 years, which is pretty long for a lizard (Green anoles live for at most five years). Many people like to keep these lizards as pets because of their astonishing appearance. Some people get mad at their anoles for biting them or getting too big and toss them back out into the wild without knowing what might happen to them. If somebody buys a knight anole as a baby, the lizard might not know how to act in the wild once released. In these cases, the knight anoles are usually considered an easy meal for snakes because of their lack of survival skills. Fewer natural predators means that the knight anole population is larger in housing developments.
    Their diet consists of insects and other smaller anoles, such as the brown anole, green anole, bark anole, or any other small knight anoles that dare come in a mightier one’s way. The knight anole also eats any insect (that is not poisonous) that gets in its way, such as butterflies, beetles, and ants. When a knight anole spots a juicy beetle, it waits in silence and turns its color to match brown bark or green leaves/grass so the prey doesn’t notice. The lizard creeps closer very slowly and snatches the beetle up in no time at all! It munches on the prey with its razor-like teeth. Knight anoles don’t usually fight over food because there are plenty pesky bugs in Cuba and Florida. In captivity, they are known for eating pinky mice.
    Knight anoles are fierce warriors, just like their name, when they meet a predator or a rival male. When the lizard sees its only predator, a snake, it turns sideways, extends the dewlap, raises the back crest, and gapes menacingly at it. This isn’t all a bluff. If the snake comes any closer, the anole will hiss or bite. If the snake moves closer to the anole, the lizard runs away. Sometimes, a snake might get the anole’s tail within its grasp. The lizard’s tail then falls off. Then a new tail will grow back, though it is replaced with cartilage, not bone, so the new tail isn’t as tough as the old one.
Fighting with other males is much different than fighting predators in the knight anole kingdom. Lizards might fight over territory or a mate, but they always fight the same way. Both males extend the dewlap and retract it many times while bobbing their heads stiffly up and down. I think that this behavior looks like the lizard is doing push-ups to scare away others. This is all about bluffing to show who is mightier. Sometimes, the fights turn into battles where the lizards nip at each other until one goes away. The winner gets to keep the territory, or the mate. Sometimes, people call the knight anole “the new Godzilla” because of its fearsome look when defending territory or mates.
    The breeding season for knight anoles is in the summer, or the spring if the temperature is right. Sometimes, the knight anole mistakes males for females when breeding because the reptiles can’t tell the difference between the two. This comical event doesn’t lead to anything serious, just a possible fight for territory. When two knight anoles breed, the female produces up to four clutches of one to two eggs. The female lays them in a depression in the ground and then covers the leathery eggs and leaves them alone. After five to seven weeks, little one to two inch lizards emerge from their eggs to greet the world. The hatchlings are a bright green with white bars on their sides and are already fully independent. Many predators such as birds, other lizards, and small mammals eat these newborn lizards because they haven’t learned much about survival yet. The hatchlings that survive the early days of their life change drastically as they grow from 2 inches to the massive 19-inch length of an adult knight anole.
    The knight anole is a truly magnificent creature that awes me. Its size, name, and abilities make it very unique. I think that it is the most fearsome and ancient looking reptile in the anole kingdom. I also think that there are many more things to learn about this lizard, such as how long the largest one is and how they came to America. What still makes me gawk at this lizard is that fact that it has come from a completely different country and has made its home in Florida along with all of the other amazing reptiles here. I wonder if the knight anole will crossbreed with another lizard species to make another extraordinary new type of lizard. The possibilities are endless and there is still much more research to do on this lime green beauty.

Back to your host:
The above was written by my niece.  To my eyes, this is wonderful science writing and I'd like to see more of it, in more venues.  Certainly I encourage such lively, passionate writing.  If a teacher is reading, take this for a model, not the vapid soulless passive 'it has been observed that lizards are green' writing that is inflicted on scientists by most journals.
