Similarities and Differences
Great work so far. By Friday it was more clear to me how inquiry is common to all human understanding/exploration/generation of meaning. Each domain can be characterized by a process of inquiry that continues to give birth to revised and novel stories, some about ourselves, our emotions our hopes and fears, some about the external material world that we live in as well as stories about our emotions, hopes and fears. Many comments to this effect in the online forum as well.
But what about the differences between the Humanities and the Sciences.
Let's Compare and Contrast:
| Humanities/Art/Music | Sciences | |
|
Ultimate Goal
|
Understanding, Creation of Meaning | Understanding, Creation of Meaning |
|
Proximate Goal
|
Exploring Human emotions, artifacts and self |
Exploring material world, mostly outside of self and human emotions ( some overlap with humanities particularly with cognative sciences). |
|
Observations/Evidence
|
Self reflection on emotions, human artifacts. |
Reflections on subject using controled, repeatable, falsifiable methods. |
|
Interpretations
|
Priveledges self expression and the subjective. |
Priveledges interpretations that minimize subjective points of view. All interpretations are subjective, but science strives for explanitory narritives that remove as much interpretation as possible. |
What needs work in the above table? Additions? Subtractions?
Both are story telling, but about different "things". The only difference is the content.
Another difference is the tools each domain primarily use.
What about the similarities and differences between a Bacteria, a Strawberry and a Human?
List as many similarities as you can between a singled-celled Bacteria, a Strawberry and a Human:
- - dna or rna (nucleic acids)
- - alive
- - perform complex chemical rxs
- - bounded: membranes, lipid/liquid fats
- - cells
- - made of parts
- reproduce
- need food, source of energy
- texture
- need water
- respire/metabolize - break down energy
- rhythms
- produce outputs
- hold 'em
- protein
- sugars
dna
reproduciable
genes
genetics
chromosomes
double helix
crime scene investigation
research
organized
heredity
forensic
code
bleach

Check out the quote
If you go into the lesson plan that I linked prior to this entry there is a quote on the last page that is interesting in regard to the point of view of the Inquiry Institute. The quote reads as follows:
“The greater the scientist, the more he is impressed with his ignorance ofreality, and the more he realizes that his laws and labels, descriptions
and definitions, are the products of his own thought.
They help him to use the world for purposes of his own devising rather
than understand and explain it.”
--AlanW.Watts
Greetings from the Keystone Summit!
Hi All!!
In addition, I found this lesson plan that you might want to critique for it's inquiry value. (http://scienceteacher411.com/berry_dna.pdf) We are working 8am to 9pm at this Technology Summit and I am very tired but learning a great deal!! Hope to see you late Thursday, BTW, where are the Institute films on Serendip, so I can try to use them to make a clip? ( Hey that rhymes)! JoyceThe Demarcation Problem
Despite desperately wanting to find a meaningful difference between art and science, I have not yet succeeded. It is possible to attribute this failure my lack of knowledge about art in terms of history and philosophy. With enough knowledge, I might be able to come up with a distinction.
However, I am not sure how useful it would be. I already know there is an intersection between the methodologies of art and science, darkroom photography is an example. A conceptual overlap occurs in the concept of symmetry as used in printmaking and chemistry. The great overarching story of art and science is inquiry. This leads me to question at what level is differentiation significant?
DNA Inquiry Lesson- Diane, Judith, and Susan
Middle School -Heredity Unit
OPENING QUESTIONS
1-What things do you think you have inherited? Make a list on board.
2- How do you think you have inherited these traits? Make a list on board.
3- Who do you think you inherited these traits from? Make a list on board.
4-What do you think DNA is?- Brainstorm and write on board.
ACTIVITY
STRINGING BEAD NECKLACE ACTIVITY
Provide string and various colors of beads
In lab groups, string one necklace (chromosome)
Necklace= chromosome
Bead=genes
Report out how & why they designed their necklaces.
Why are there different lengths & different number of beads ?
HOMEWORK
Write your own definitions of chromosome and gene.
D AY 2
Share definitions
Questions-
Go back to opening question #2 list
How do you think you inherited these traits?
Try to get students to the point where they understand that each trait is a gene (bead) and the genes are located on the chromosomes (necklase). Some genes are on the same chromosomes, so all these genes are inherited together.
Each child inherited a (necklace) chromosome from each parent with the genes (beads) that are on that chromosome.
ACTIVITY:
Heredity Activity:
How many students have: Widow's Peak, Attached Ear Lobes, Cleft Chin.
Who shares what traits? Create chart. Are you related?
Possible Extension:
Ask students to survey family to see who else shares traits. Use activity from Prentice Hall Life Science chart & numerical grid.
3rd day
Discuss the students findings & compare with classmates.
In class Inquiry Questions-
What material is a chromosome made from? (DNA)
Guide them to the knowledge that the whole chromosome is made from of DNA.
If that is so.....then what are genes made from?
BRING OUT THE NECKLACES- review that DNA is organized into genes along the chromosome.
INQUIRY QUESTIONS
1-How can one gene differ from another gene if they are all made out of DNA?
2- Problem- There are only 4 different kinds of DNA, how they can there be 25,000 different genes?
3- Teach Triplet Code.
ACTIVITY
DNA Extraction from Strawberries
PREDICTION; What do you think the DNA will look like?
Do experiment
DISCUSSION QUESTIONS
Did the DNA look like you thought it would?
How did it feel?
How do you think the DNA from the strawberry compares to our DNA?
Is it different?/ How would it be different?
END OF UNIT
The students will understand that the code makes the strawberry's DNA different from our DNA.
Heredity Activity for Diane, Judith, Susan's DNA Inquiry Lesson
Awonderful activity with both qualitative and quantitative components.
Prentice-Hall Life Science text for Middle School, 2008, Chapter 3, pages 82-83.
The activity explores dominant and recessive traits as a way of determining the uniqueness of different combinations of inherited trarits.
The activity can be confined to the students in the class or can be extended to include the families of each student.
At the conclusion of the activity, students can post their results and compare them to the total results posted to the site.

Strawberry DNA Fields Forever (FYI- from my blog)
Strawberry Fields (DNA) Forever
Submitted by Jacob Marine on Mon, 07/28/2008 - 2:33pm.OK, Mr. Franklin, I missed your strawberry DNA extraction. It's not that I don't find this an interesting subject, it's just that "something got in the way" this morning. I do wonder if my genes or my influence will have an altering effect on my children's habits and behaviors over the course of their lives. I know that my DNA gave both of my teenagers their flat (large) feet and curled toes. I know that my wife's DNA gave our son Max his blue eyes and our daughter Dakota has my brown eyes. Max has recently found new ways to "harness" his appearance to perpetuate an attractiveness to the opposite sex. Is that because of different body shapes originating from our combined (my wife's and my) DNA?
There is going to be a Mind Body Spirit Expo in Philadelphia in October of this year. Do we get our mind, body and souls(spirit) from how DNA is deposited into our bodies, or do we depend on our environment to create these combinations? How will Max and Dakota's life journeys turn out? Max says that we made a lot of mistakes in the way we raised him, and that who he is- is based on his own sculpting. But I know better and that it will hit him at various juntures in his life's travels that we did have positive influences which are, and will be parts of his mind, body, and spirit.
Arts/Sciences- a never ending dialogue with myself
The free association sessions in this Institute have been useful to me to solidify ideas I have but have not put into words. What differentiates the Arts and the Sciences?? They are both creative. They are both investigative. They both involve the concrete and the abstract. In both, information and technique build upon the previous work of others. Is it just content forming the frame of reference and the "tools of the trade" that are the difference between them? What makes my daughter the artist (art historian and architect) and myself, the scientist (biology and neuroscience). Both of us have been teachers. Our early childhood experiences were dramatically different. Hers were more enriched. The physical and emotional care we received as children were also dramatically different. We share genes but not all genes. We are not the same and yet share many characteristics. OK back to the question. Why do we look at the world with different content and tools? Is it the arrangement of the tendons, ligaments, and muscles in our bodies or the way our neurons have made connections with other neurons in our brains, or both. Is there something about the way we transport oxygen that differs in the left and right hemispheres of our brains? She is after all left handed/ambidexterous and I, definitely right-handed. What allows my right-handed son and I to share a fondness for expressing ourselves in poems? He is not a scienctist but a poet, writer, and businessman. The difference must lie in the "wiring" of our central nervous systems rather than in the anatomy of the muscular system. In that system, we might find the differences in raw athletic talent. But again, we would have to look to the brain to find the differences that underlie a preference for single driven sports like figure skating versus team driven sports like soccer. Both utilize similar skills.
How does all this relate to teaching in an inquiry based classroom? Children need to have the time and freedom to understand what they enjoy and what gives them a feeling of success. A child can enjoy most disciplines if presented in an open environment. My example is my student who earned D, F, D in the three trimesters of Grade 7 Science but announced that science was her favorite subject. The experience opens possibilities for her to investigate a place for herself in science. She needs to have that same experience in the Arts and in the Sciences in order to choose a life path in which she will find pleasure and success.
Strawberries
Thanks for this experiment. It was fun and thoroughly engaging. I don't know how it will be received in the Pre-K classroom, but I think I will try. Maybe just using it during the Human Body lessons would be best. I think simply talking about how we are all different because of something in our body called DNA would work. The concept of being different could be illustrated at the gross level by how we all look alike and at the finer level by painting our fingertips. Children could use the magnifier to look at the different patterns of the each other's fingertips. Then once we all agree we are different and it's because of DNA (DNA makes you what you are), I could ask if they want to see some DNA (DNA that makes a strawberry be a strawberry). There we go..... OF course, cross-curricular learning, and if you want it to stick, use a song, I would have to make a song about DNA.
TO the tune of Three Blind Mice:
DNA, DNA it makes me, me
It makes you, you
DNA has all the say
DNA makes me look this way
DNA,DNA
PS Is the DNA for each strawberry the same?
Reflections: On Inquiry, art, science, and strawberries
Before this morning I was quite comfortable with my definition of art, humanities, and science. Now the differences are not so clear. There is more gray area. I will have to digest the discussion and reformat my geshtalts (sp?) over the next few weeks.
The discussion didn't give me any more in the way of methods or ammunition that I could use to have my students go after the material themselves, tho. I will still have to find these activities myself. One suggestion that was made that I might be able to implement is to begin each new topic with an inquiry activity . . . and then move ahead in the normal manner after that. It might be worth a try.
The strawberry DNA extraction was more rewarding than I thought it would be. The procedure worked easily and as predicted. It also left us with some questions that we could pursue (for further research, should we wish). I can see where this would be a simple lab that a bio teacher might run in one period . . . and provide some other material and apparatus for the kids to use to go to the next step. I'll definitely be checking this out with our bio teachers.
Morning session reflections
Good thought provoking discussion on the Arts/Humanities vs Science.
The experimenting with extracting DNA from a strawberry was a fun learning experience. It was interesting to see the curiosity of what would be the results of mixing the different solutions. This is something that the students would probably want to find out.

Strawberry DNA Extraction
Making sense of inquiry? Sciences/humanites/social sciences/art
Maybe some of our problems with understanding the relation between sciences, humanities, etc have to do with the relations being evolving ones? How about the following as a way to bring things together, both in terms of objective and in terms of time?
Open-ended transactional inquiry = the process of continually generating new understandings, individually and collectively, a common objective of all human creative activities
Strategies/tactics
clear this up?
Inquiry - contemporary and beyond
Including what I mentioned earlier in this mornings discussion
