Vols ajudar a la NASA a trobar nous planetes al voltant d'estrelles llunyanes? Doncs es pot fer des de casa, o des del mòbil. De fet la NASA està demanant ajuda a tots aquells que estiguin interessats.
Com? Fàcil, s'ha de mirar imatges captades per un dels seus telescopis i dir si hi ha un núvol planetari o no. És una feina que a nosaltres ens resulta fàcil, però a un programa informàtic li costa de fer.
On? A Disk Detective un projecte més de Zooniverse, una iniciativa que intenta aprofitar la curiositat que tenim tots per ajudar a les investigacions científiques o d'humanitats, en temes tan diversos com la vida dels antics grecs, o el dia a dia dels soldats a la Primera Guerra Mundial, o estudiant galàxies, identificant animals al serengueti, explorar Mart, ...
Si tens curiositat científica, i vols col·laborar en la investigació de primer nivell, Zooniverse és el teu lloc.

UNA SETMANA AMB LA CARISSA JANSEN, ESTUDIANT DEL MIT
Oak House col·labora amb la MIT participant en el
programa MISTI.
La
universitat tècnica de Massaxussets és una Universitat
americana que gaudeix de molt prestigi, tant els EEUU com a la resta del món. (
http://web.mit.edu/
)
Els estudiants a més de formar-se
acadèmicament poden utilitzar part de les vacances per prendre part d’altres
programes de formació que complementen els seus estudis.
Aquesta setmana hem
estat col·laborant amb Carissa Jansen,estudiant
de MIT que participa en el programa MISTI. ( http://web.mit.edu/misti/
)
Aquest programa
consisteix en tenir diverses experiències docents de manera que puguem aprofitar mútuament dels coneixements i
de la metodologia que es practica en els
dos països.
La Carissa ha estat
aquesta setmana passada intervenint en diverses activitats escolars a Oak
House. Ha participat en les classes següents:
BIOLOGIA 1r BATX:
Treball amb models moleculars analògics i digitals. Ús de diferents programes
de construcció de molècules.
BIOLOGIA 2n BATX:
Experiències amb bacteris al laboratori.
CMC 1r BATX:
Elaboració dels codis QR de les nostres aules.
ECONOMIA 1r BATX: La Carissa
va fer una xerrada sobre el branding, és a dir de quina forma es pot generar
una nova marca i quines estratègies s´ han de tenir en compte. Els estudiants
de primer que participen en el projecte de
Junior Achievement van compartir amb ella els seus projectes i van rebre
consells sobre segmentar els seus mercats o reforçar el valor de la marca.
TUTORIES 1r i 2n de
Batxillerat: Cada cop més, un nombre més important d’alumnes de Oak House es
plantegen estudiar en universitats del Estats Units. En les tutories , la
Carissa els va donar informació i va respondre
les preguntes del nostre alumnat respecte el procés de selecció de les
universitats americanes.
TUTORIA 4t ESO:
Els alumnes de 4t d’ ESO
van poder assistir a una conferència sobre la MIT. A més, van poder parlar amb
la Carissa Jansen sobre el seu futur acadèmic i professional i sobre els
principals requisits d’accés a les facultats dels Estats Units.
ASSESSORAMENT INDIVIDUALITZAT:
Els alumnes que tenen interès a fer estudis Universitaris a EEUU han pogut gaudir
d’ un assessorament totalment individualitzat fins i tot de qüestions tan
pràctiques com aconseguir vols bé de preu!
El centre que ens ha
proposat aquesta col·laboració ha estat el CRG (Centre de Regulació
Genòmica), amb qui tenim altres Projectes programats.
Agraïm des d´ aquí aquesta gratificant
col·laboració.
I had a wonderful week teaching the students in 4 of eso
and bachillerat at Oak House School. More than any other school I have visited
in Barcelona, I was immensely impressed by the level of interest and discipline
that the students placed on their academics. I taught biology, English, and
economics to the students in science and letters. All of them were driven and
attentive, and I was surprised by how many of them wanted to study abroad.
Hopefully my week at Oak House helped the students to learn more about science
and universities in the United States. I certainly learned much from them too.
Lastly, I'd like to give a message to all of the students who I met and spoke
with at Oak House: I wish you the best of luck in your studies, and maybe I
will meet you again at MIT someday!

Cultural week-Secondary Science (1st to 3rd ESO)
As part of their cultural week, students from 1st
to 3rd ESO were asked to research, carry out and explain some of the
more interesting experiments that can be found in Science. These experiments
included a corn flour bomb, exploding bubbles, peculiarities of static
electricity and the crushing can experiment.
The idea behind this was to get the students to have a
chance of doing these fun experiments, learn the science applications behind
them (which are based on material they have already covered in class) and to be
able to communicate this information to their peers in a fun way. There was
also another agenda to this…..the plan is that these experiments will be
demonstrated to you, by these students, on Family day!! We plan to set one of
the labs aside as a demonstration area and have a timetable of events planned.
Watch this space for more details…..!!!
Divya "burning" paper without the paper actually burning!! How is this possible??
Yashica doing the same as Divya above but with a lot bigger flame. But why doesn't the paper burn?
Below Bhavesh "detonates" the flour bomb constructed by students of 3rd ESO. (Thanks boys and girl).
Finally Isabel and Priyanka make an explosive and bubbly cocktail.
My ears are still ringing!!
Descubierto en Atapuerca el ADN humano más antiguo del mundo
Un equipo internacional de científicos ha extraído la muestra de ADN humano más
antigua del mundo de
un fémur de 400.000 años de
antigüedad hallado en la Sima de los Huesos de Atapuerca.
Los resultados de la investigación, presentados en la revista Nature, han desconcertado a los científicos. Los antiguos habitantes de Atapuerca no parecen ser ancestros directos de los neandertales que después poblaron Europa, como se pensaba hasta ahora, y en cambio parecen estar más emparentados con humanos que vivieron en Denisova (Siberia) hace 40.000 años.
“Tenemos un problema para interpretar estos resultados”, reconoció el martes en entrevista telefónica Juan Luis Arsuaga, codirector de las excavaciones de Atapuerca y coautor de la investigación. “Siempre habíamos supuesto que los homínidos de la Sima eran neandertales primitivos” porque sus fósiles son parecidos a los de los neandertales. “Ahora tenemos que buscar una explicación que aclare cómo podían ser anatómicamente parecidos y genéticamente más diferentes”.
La Sima de los Huesos es una cavidad en el fondo de una cueva en la que se han hallado unos 5.000 fósiles de por lo menos 28 individuos atribuidos a la especie Homo heidelbergensis. Aunque en otros yacimientos de Atapuerca se han encontrado fósiles más antiguos, como los del Homo antecessor en sedimentos de hace alrededor de un millón de años, los de la Sima de los Huesos destacan por ser los más abundantes y mejor conservados. La oscuridad y la estabilidad de temperatura del fondo de la cueva han favorecido que se haya podido recuperar ADN humano más antiguo que en cualquier otro yacimiento.
La investigación indica que los humanos de la Sima de los Huesos se separaron del linaje de los neandertales y de los Homo sapiens hace alrededor de un milllón de años. La familia humana evolucionó a partir de ese momento en dos ramas, según los resultados del análisis genético. Una que llevó a los humanos de la Sima y a los de Denisova, que se separaron hace 730.000 años. Y otra que llevó a Homo sapiens y neandertales, que se separaron hace 500.000 años.

Pero estos resultados no serán la última palabra, advierte Arsuaga. Son una primera pieza de un rompecabezas que se podrá completar a medida que se hagan más análisis de ADN humano prehistórico.
Para los especialistas en paleogenética, el ADN mitocondrial tiene la ventaja de que es más fácil de analizar que el nuclear. Esto ha permitido a los equipos de Atapuerca y del Max Planck reconstruir casi todo el genoma mitocondrial del fémur analizado. En el futuro, los investigadores tienen previsto intentar recuperar también fragmentos de ADN nuclear, informa Arsuaga.
Dado que el ADN mitocondrial sólo se transmite por vía materna, Arsuaga recuerda que pueden coexistir distintos linajes mitocondriales dentro de una misma población. Por lo tanto, sigue siendo posible que aquellos neandertales de los que se ha analizado el ADN desciendan, no directamente de los Homo heidelbergensis de Atapuerca, pero sí de un grupo similar. “Seguimos pensando –declara Arsuaga- que los de la Sima están emparentados con los neandertales”.

Uno de los resultados más importantes de la
investigación, precisamente, es que abre la vía a reconstruir secuencias
genéticas humanas del pleistoceno. El propio equipo de Atapuerca tiene previsto
analizar el ADN de más fósiles de la Sima de los Huesos para comprender mejor
cómo evolucionó la humanidad hasta llegar al Homo sapiens. Para ello, se ha
aliado con el equipo de Svante Pääbo, del Instituto Max Planck de Biología
Evolutiva de Leipzig (Alemania), que es líder mundial en estudios de ADN
antiguo.
Por ahora, la investigación se ha centrado en el
llamado ADN mitocondrial de uno de los 28 individuos encontrados en la Sima de
los Huesos. Este ADN representa una pequeña parte de todo el ADN de una célula.
Es el que se encuentra en las mitocondrias –un compartimento de las células- y
no incorpora ADN del padre sino únicamente de la madre. El ADN nuclear, en
cambio, cambia de generación en generación porque combina ADN del padre y de la
madre.

What is the relationship between whale faeces and 9/11?
And well you might ask that!
Yesterday, whilst listening to a podcast, they were talking about how noise from offshore wind turbines and shipping might be affecting sea-life like whales and fish. Research is showing that more and more sea creatures (if not all of them) use sound to communicate and our noise pollution is probably affecting this.
But how do you show that?
It has been shown that noise pollution has an adverse affect on humans and terrestrial animals alike but how can you show it in sea creatures?
Well when 9/11 occurred, as well as air traffic being reduced, shipping traffic was also reduced. Scientists analysing whale faeces (where would they find this stuff?) which they were doing anyway, found that levels of stress factors present were greatly reduced. i.e. whales were less stressed when shipping (and its noise) were reduced!!
This is why I love Science!! It's a shame that something like 9/11 had to happen to be able to show this. And are we reducing shipping because of it.....?

CMC - La Crisis Del Pepino
EL COGOMBRE ESPANYOL NO VA SER EL CULPABLE
Recordareu que fa 2 anys i mig la ministra de salut d´ Hamburg va acusar el
cogombre espanyol de provocar un brot d’ E. coli. http://elpais.com/diario/2011/06/01/sociedad/1306879202_850215.html
Aquest fet va tenir conseqüències econòmiques
molt greus pels agricultors del nostre país.
Els alumnes de CMC han preparat una campanya
publicitària que s’hagués pogut utilitzar, estic segura que amb molt d’èxit,
per netejar la mala imatge que es va generar
després d’aquest incident.
Aquí
tenim dos exemples de materials proposats per la campanya:
Programa Joves i Cièncias
This is a program that is run by Fundació Catalunya La
Pedrera that is very well worth entering for. This program runs over three
years and is aimed at 4th ESO students. Students will participate in
Scientific research with Universities both locally and internationally in a
number of different areas.
One of our 2nd Bachillerato students, Pepe
Amich, was lucky to be awarded one of
the 50 places when he was a 4th ESO student. In his first summer
with this program he was working on molecular modeling of a cell receptor
thought to be implicit in a certain type of cancer. The Science he was working
on was cutting edge and the things he learned invaluable. If you thought that
was enough, in his second year he was off to MIT in the United States where he
worked with an eminent scientist in another field. From this work he became a
co-author in a scientific paper published in a top Science journal. From these
experiences (and he still has one more summer to go) many doors have opened for
Pepe, including acceptance on another course “Bojos per la Ciència” and also
acceptance into Harvard where he starts next September. The experience for Pepe
has been invaluable and has just fueled his love for Science.
So if you are a 4th ESO student and love
Science; if you plan to continue your scientific studies in Bachillerato; if
you can see yourself pursuing a career in a field of Science; then you need to
apply for this program!!
When asked, Pepe said the best thing you can do when
applying is to sell yourself and your capabilities. If you want more ideas from
him then find him and ask.
The closing date is the 21st of February.
If you need any help or references, please contact a member of the Science
department.
For more details check out: http://www.jovesiciencia.com/Oak House School Science Fair…time is running out!
Last November the Science department proudly launched
its first ever Science Fair and since then interested and enthusiastic students
have been getting together to decide on their projects and start on the path of
research.
Twenty two groups across the four age categories have
embarked on their projects hoping to be the first winners of this competition.
Over half of these groups have come from primary showing the great enthusiasm
they have for Science.
Projects range from microbial analysis of the school
to looking at the energy consumption within the school, with lots of other
fascinating ideas in between.
If you are interested in participating then you need
to decide on a project and get started as soon as you can. The closing date for
entries will be Monday 31st
of March where students will need to submit a short video showing what
research they did, the results they found and the conclusions they can make.
There will be a first round of judging and successful
candidates will be asked to give a poster presentation for Family day (May 19th
in the labs) where the final winners in each category will be decided.
Though the prizes haven’t as yet been decided on they
promise to be something special and worth competing for.
Through this Science fair, we, (as a Science
department), hope to fire up the imaginations of our students and teach them
the skills needed for proper scientific research. This will aid them with their
future treball de recercas/extended essays in Bachillerato/IB and further on in
University.
Nine weeks left! Good luck to all!

Science demonstration videos by 3rd ESO students
As part of our Science enrichment project, three 3rd ESO students, (14 to 15 year olds for those not familiar with the ESO system), chose to film some Science videos which could then be used in class (which I did yesterday!!).
Please enjoy their version of electrolysis, (see if you discover the hidden meaning of the frogs) and the making of a smoking device (which you will see shows that not all Science experiments work as you would like!) (By the way I haven't given the actual name for the second video for fear of getting the undue attention of the NSA but then this might boost our readership).
Let us know what you think??
Thanks to Isabel, Eric and Adriana for the videos!!!
Note:
Under no circumstances should you undertake any of these experiments without proper supervision. This students carried out these experiments under supervision and following strict safety protocols.

2nd Cycle ESO Science Enrichment Project
We are now
in the middle of the second term of this Science enrichment project and of the
24 enthusiastic students who took part in term one, 13 decided to come back for
more!!
“We love the freedom
that we have to do what we want in the lab”
was one
comment that was made at the end of the first term;
“I enjoy being able to
see what we learn in class in a practical setting”
was another
comment.
Of course,
having 24 students let loose in a lab might frighten the hardiest among us, but
every week I am surprised and delighted by the level of interest, enthusiasm
and dedication shown by these students.
Projects
being developed this term include:
·
The
development of a solar powered water purifier.
·
Materials
from organic sources including plastics and biogas (which is filling a balloon
next to me as I write).
·
The
analysis of phage DNA using restriction enzymes.
·
A
microbiological analysis of the school environment, (the results of which might
be frightening).
….among others.
The students we have show a level of curiosity
and dedication which will stand them in good stead for whatever career path
they wish to pursue!!

Exoplanets and the "Goldilocks zone"
Over Christmas I received an email from one of my students (Alejandro Mir 4º ESO Blue) with a very short piece about a planet GLIESE 581 which had liquid water and could possibly be habitable. I include Alejandro's screen shot of his phone with the relevant information...thanks Alejandro;
So this led me on to thinking about two things: the ongoing search for exoplanets (for which at the moment we have found 4,624 with 1,022 confirmed) and the "Goldilocks zone"
Both of these you can read about through the attached links but beyond that what is this telling us?
Well for one, Science is happening on a daily basis and everyday a new exoplanet is being discovered; but also why are we looking for these planets? Are we looking for other life forms? Life forms like ourselves? More advanced life forms from whom we can learn or be conquered? Or are we looking for a place to escape to when this habitable planet of ours is no longer habitable due to human or natural causes?!!
Maybe as well as looking to the sky we should look to our planet and lifeforms and see what we can all do to help preserve and nurture what we already have!!
Isn't it mad how one article can provoke so many other ideas?! Still the search for exoplanets is exciting and I look forward to more news in this field....Alejandro?
Happy New (Science) Year!!
I was involved in a conversation in the staffroom the other day which centred on the fact....when do you stop saying "Happy New Year"? The consensus was January 10th. (Has this been written somewhere and has it been peer reviewed?)
2014 promises to be an exciting year both in the world of Science and Science within Oak House.
In the world we will be able to avail of the first commercial uses of Graphene (a very, very, very thin sheet of Carbon that has a myriad of uses); see the continuing explorations by the Chinese of the Moon and wonder at what medical breakthroughs will we have....a vaccine for Malaria for example.
On the school front, we have ten weeks before students have to submit their entries for the first Oak House Science fair; students in the Science enrichment projects are continuing with their research and experimentation and plans are ahead for both the first ever Oak House Biology Symposium and a dedicated Science afternoon which is still in the planning stages.
I have been remiss in the posting of articles and the back log is mighty, but this I plan to remedy.
If you like what you read, let us know. If you have any suggestions, we would love to hear them.
So here we are and it's January 17th and I'm doing just that!
