clip_image002It’s been a while since the last blog post about the meeting in Pistoia. On the second day we had a parallel session – I was chair person for the teachers – “Teachers’ view on CarboSchools Library: What materials do we need to teach Carbo-Topics? What materials do expect to get from CarboSchools = find in the CarboSchools library?”

Here is the results from our discussion (which were sent to the CS organizers)

Experiments

  • Must have a quality check of all the resources that is put out, if we teachers know that it is checked, it might be easier to send away our ideas / experiments / projects
  • Hands-on experiments
  • Include documentation of “how to”
  • Yesterday’s presentations
  • Include background information for teachers these could be links to external pages (remember to include date and time for the link when it was added – Google Cache)

Teaching resources

  • Access to new research results, hopefully together with ideas to activities connected to the new research
  • Quality check
  • Ideas for projects that can be used “in the classroom” / with students
  • Animations

Instruments

  • “Instrument” library w/tutorials – list over instruments that can be borrowed at the research institutes
  • Reviews of different instruments – recommendations of good instruments, also about experiences that was not so good

Organization

  • The content must be organized
  • Main topics / categories – links to the main topics where the experiments are found
  • Search engine (if the content grows)
  • Discussion forum for teachers and students
  • Possibility to find partner schools / teachers – contact information to CS teachers and teachers who uses CS library and are interested in collaboration with other teachers who are doing CS experiments / projects
  • Section that includes final results from / with students (videos, animations, reports etc) – can be in native language, but should include an abstract in English

Where do we usually find them?

  • SchoolCO2Web
  • Wikipedia
  • Google
  • Encyclopaedias
  • Local universities (reports, booklets, scientists)
  • Local research institutes
  • Booklets from CS
  • Country websites about climate
  • Online journals
  • Online teachers’ resources
  • Newspapers
  • Conferences
Reklamer

Marc Jamous – Regional Coordinator in France – Predicting CO2 scenarios through models

image

1958 was the first year that the total amount of atmospheric CO2 was measured, which is the reason for the start year for this simplistic model. In this model you start by the total amount of atmospheric CO2, and after that you add fuel emission and land use.

imageThe first step is to add the emissions to the atmospheric amount. The second step would be to compare the measured and the calculated CO2 data. The students will then see that there in a gap between the measured and calculated values – CO2 must be absorbed somewhere else then in the atmosphere.

The next step is to find a suitable value for the natural absorption, as a percentage of the emissions.

This is a great introduction to climate modelling as a discussion theme with our students.

Further on it would be possible to split natural absorption in absorption by the ocean and absorption by the vegetation.

After making this model, it is now possible to include the prediction scenarios from the IPCC reports to calculate model results. It is also possible to get the students to make their own scenarios.

Camparison between the pessimistic and optimistic scenarios:

My concluding remarks: This was an easy but fantastic way of introducing the principles of climate modelling! I look forward to try this with my own students next year 🙂 I also want to thank Marc for sharing his files with us.

ASE: Experiments and Demonstrations in Atmospheric Physics

Konkrete eksempler til hvordan man kan vise atmosfærefysikk for elever.  Noen av forsøkene likner veldig på de vi så på Geofagkurset på Naturfagsenteret i oktober 2008.
Nok en gang direkte notater:

Starter med strålingsbalansen

Refleksjon: 4 bokser dekket av tin foil, to ulike lamper (lavenergi og høyenergi 200W), to hvite to svarte. Forskjellen er større ved lavenergi enn høyenergi pga infrarød stråling

 

Baking powder and vineager i et glass – lukkes, vinager in one, both under 200W lamps. Den med bakepulver skulle gitt høyere temperatur.

 

Form a cloud in the classroom: snakker om metningspunkt og duggpunkt

Brusflaske, hvis den presses sammen, så øker temperaturen inni flasken pga høyere trykk, slippes fort og da dannes skyer hvis der er nok vanndamp i flasken.

2.flasken har vann i seg, men ingen partikler à ingen skyer

Glass: Carbonated water. Salt kan brukes som kondensasjonspartikler, og da dannes det flere bobler i brusevannet. Det er inverse skyer.

I vannflasken: setter fyr på en fyrstikk, slipper den ned i flasken og der vil være røykpartikler som dampen kan kondensere på.

 

Kaos: enkeltpendel og dobbelpendel

Dobbelpendelen er ganske lik i starten, men blir svært ulik etter en stund, og det er med å forklare hvorfor værmeldinger er mye mer nøyaktige i starten enn etter en stund. Viste animasjoner av dette.

I tillegg: sprettball mellom plater

 

Hvorfor er himmelen blå?

Solstråling som treffer atmosfæren. Farger i lyset, som kan deles i prismer.

Atmosfæren: gassmolekyler, vann (dråper, gass og is), og små partikler (støv etc). Partikler som er mindre enn bølgelengder, gir scattering av lyset. Våre gasspartikler i atmosfæren passer inn med dette og vi får det blå spredd. På kvelden må lyset gå en lenger avstand, og dermed er det blå og grønne scattered away.

Tank med vann og litt melkepartikler pluss en lampe, mørkt i rommet
