Article on post-grad salaries

The Washington Post on may 24 ran an article comparing average annual income of graduates with various majors.  It included the joke:
The scientist asks, “Why does it work?”
The engineer asks, “How does it work?”
The English major asks, “Would you like fries with that?
Check it out:

Feedback from Bailey's Elementary School in Falls Church, VA


Bailey Elementary's Science Coordinator Lynn Riggs sent the note below on this term's ReSET program 
by Volunteer Kojo Opoku:   
We had a great experience with Kojo.  He worked very well with me as well as the 
classroom teacher.  He was very dedicated, designing and preparing interesting 
experiments in electricity for the 4th grade students.  It was wonderful to have 
an engineer-in-residence.  He helped me out in the science lab by developing a 
demonstration generator that I've been able to use with all my classes, along 
with trouble shooting some of the equipment and experiments for me.  I know the 
4th grade teacher really appreciated having Kojo work in her classroom. 
 Many thanks to you for setting this up!

Beverly Yett's Adaptive Evolution Experiment

The two things the students seemed to be most excited  about were the facial reconstruction and what they called the bird beak experiment.  This was a bit of a diversion for me but I wanted to demonstrate both biodiversity and adaptive changes to the environment.
The students made "cootie catchers" a simple origami form that you may remember  as a fortune telling thing or a color guessing game or some such (I'll show you how if you don't remember them, in two sizes.  I distributed different sized  squares of paper-large and small.
There were two types of "food"  ( I used large and small wrapped candies-you can use pebbles, M&Ms  etc.)
The idea was that when food was plentiful, the large beaked and the small beaked birds got enough to eat so they could reproduce.  (we did timed food gathering several times and averaged the results)
 After a drought on one Island, the "small" food disappeared since the plants died.  The small birds didn't get enough food to reproduce and pretty much died out in that area. On a neighboring Island, there were floods and the "large" food producing plants drowned. The large beaked birds couldn't reproduce because they did not have  enough food.  
Fast forward 200 years and you can see that the populations on the two Islands are different and if they come together, they occupy different ecological niches.
That was very popular with the teacher and the students.

Fall 2010 Student Assessment Results

In Fall 2010 97% of student responses to ReSET's Student Assessments indicated they enjoyed the classes (The percentage for school year 2009-2010 was 99%).  Yet the percentage of students who disagreed with the statement "Science is boring" declined from 91% last year to 81% in fall of 2010.  Please post a comment if you have any thoughts or insights about these results.

Report From ReSET Pre-K


        I teach science to two, three and four year olds at the NSF Child  
Development Center in Ballston, VA. 
 Last Tuesday when I was working with my two year old day care  
children I learned something about teacher involvement.  I had  
brought some small bar magnets for them to play with and discover  
what magnets can do.  When one boy found that he could not make a  
North pole attract a North pole, I realized that he did not know his  
letters (he was two after all) so I just turned the magnet around and  
he was satisfied. 
 Then I heard laughter and looked at the end of the table where a  
teacher was playing with three two year old girls and some magnets.   
The teacher had never seen a bar magnet and was finding out what they  
could do in attraction and repulsion.  She and the girls were having  
a grand old time  learning the basics about magnets. 
 Isn't that what ReSET is about showing that science is fun?

Is there a Ben Carson in your ReSET classroom?

ReSET Volunteer Bob Williams writes: 
I'm sure that this is not new for many, but at out meeting I spoke to a 
couple of people who did not know the Ben Carson story, so here is a 
tickler. 
 
Ben Carson rose from poverty and inner city chaos to become a world-famous 
pediatric neurosurgeon at Johns Hopkins.  I found his story to be 
inspirational for teachers, volunteers, parents and children.  Here is an 
excerpt from an interview: 
 
My fifth grade science teacher, Mr. Jake, was really the first teacher to 
express confidence in my academic abilities because I was the only person 
who could identify a rock, which was obsidian, and it was because of the 
reading that I had been doing because after I got through with the animal 
books, I went to plants, and when I finished all the plant books, I went to 
rocks because we lived on the railroad tracks and there were a lot of rocks, 
so I became an expert in geology, and this was while I was still a dummy in 
the class. So, it was like the first time that I had an opportunity to raise 
my hand and demonstrate my knowledge because nobody else knew the answer. 
Everybody was absolutely flabbergasted, but Mr. Jake said to me, "Benjamin, 
that's incredible." He said, "Why don't you come by the laboratory after 
school and we can talk about starting a rock collection for you." And, from 
there I started going to the laboratory every day, getting involved with 
feeding the squirrel, a red squirrel named Maynard. There was a tarantula, 
crayfish, a Jack Dempsey fish and I got involved in all this stuff. There 
was a microscope and I started looking at water specimens and learned all 
about paramecium and volvox and amoebas, and it was just incredible. That 
really was what started me on my way. 
 
His story "Gifted Hands: The Ben Carson Story" is available in book form 
(adult and children versions) and also a DVD (although the richness of the 
book is not to be missed).
