M&L 2012 - Videos: a high tech, low cost, hands-on approach to the physiscs of nano materials - by Annamaria Lisotti

  1. 1. Media and Learning Conference Bruxelles 14th-15th- November 2012 ●Università degli Studidi Modena e Reggio E. Videos : a high tech, low cost, hands-on approach to the Physiscs of nano materials for high school pupils Annamaria Lisotti *°# G.Goldoni°#, V.De Renzi°# *ISIS Cavazzi sez. Scientifica – Pavullo (MO) °University of Modena and Reggio E- IT- Physics Informatics Mathematics Department #CNR Nano, Modena annamaria.lisotti@unimore.it 1
  2. 2. Setting the frame: Nanolab ProjectNew ierarchy in forces Atomic manipulation Quantum tunneling Size matters!selfcleaning smart materials pressure sensors colorimetric sensorssuperhydrophobic stents, artificial muscles drugs deliverysuperadhesive surfaces conductivity, Light and matter interaction Phase transition resistanceForces , friction, adhesion, piezoresistance, colour, spectrometry, metal dilation, sound diffusion  Low cost, simple, safe, robust From EU  Still teaching fundamentals , strongly link to curricula input …  Sometimes challenging “school linear physics”  Can be taylored to suit different needs and levels … to local  Students as young researchers IBSE implementation
  3. 3. www.nanolab.unimore.it August 2013 Modena IT Background reading + Seminars Video PPT Teacher guidesVideo lab Didactical notes Lab sheets & Detailed buildingguides presentations instructions ‘Where to buy’ tips
  4. 4. 1. Video Lab Tutorials Teachers  Preparing for the lab: a preview of what they have to do  no time wasted, appropriate questions,  Support in revising after on site course  Distant training tout court Students and flipped classrooms  Better comprehension of what they are going to do  concentrate on the lab task. Less dispersive .  Possibility to revise what has beenSMR recorder free done once back at home at their ownsoftware: recording pace.screen dynamic content tutorials, etc…  They like it! Importance of visual language for youth
  5. 5. 2. Documenting (lab work) To design and edit a good video students have to  activate careful reflection on content, procedures and the logic behind each step.  understand the topic thoroughly -analysis  decide the focal points - synthesis  refine communication techniques (aesthetics) By doing this they  make use of extracurricular competences  appreciate the potential of their ludic portable technology as powerful working tools  become actively engaged: labs too can be VERY boring too! (motivation)  Promotional Value (projects & sponsors)
  6. 6. 3. Powerful science tools for high tech hands-onWe often complain of not well equipped‘up to date ‘ labs BUTstudents daily bring in high tech devices atzero or very low cost which can Promote practical skills development Stimulate scientific enquiry methods Help make abstract concepts visibleIssues Teachers don’t feel confortable Many schools have rules against the use of cell phones inside the classroom Students are not always aware of the enormous potentialities of their own devices for educational purposes. …some examples !
  7. 7. 3.1 Superhydrophobics /liquid marbles Rolling  1,5 sec Tracker free software www.cabrillo.edu/~dbrown/tracker/
  8. 8. 3.1. Drops motion Sliding Stick and slip
  9. 9. 3.2. Application example A nitinol spring contracts in  8-10 s : TOO FAST for hand measurements of the spring lenght. Boosting observation sensitivity: Tracker : 25 frames per sec  measurements allowed each 0,04 sec VS  1 sec average human reaction time Access to much more information !  steps and stops! Alternatively the experiment could be TOO SLOW and time consuming (equilibrium spring heating + cooling: 2.5 h) Monitoring multiple measurements at the same time
  10. 10. ‘Microscopio’ acustico 3.3. Acoustic ‘microscope’ Memory metalsAustenite &Martensite …44100Hz 8100Hz Audacity free audio recording and sound analysis
  11. 11. Frequenze 3.3. Frequency shiftIron Rod Nitinol Rod Fundamental frequency versus temperature
  12. 12. 3.3. Using data from research videos Videos are taken in research labs by researchers (sophisticated equipment) but students can work on them Calculate : Work Efficiency
  13. 13. www.nanolab.unimore.it Food for thought Open to collaboration … 1. Students should be encouraged to bring their own devices and use them in school.2. Making a video of experimental work may have as much/more/less? value compared Modena to classical reports annamaria.lisotti@unimore.it Thank you for your attention !
