  3. TODAY’S PRESENTATION INTRODUCE THE LESSON PLAN OF A TYPICAL CLIL LESSON ABOUT OHM’S LAW POWER POINT PRESENTATION ABOUT OHM’S LAW PRESENT SEVERAL DIFFERENT CLIL ACTIVITIES USEFUL TO PREPARE A LESSON

  4. PREPARE A CLIL LESSON

  5. 8) LESSON PLAN 1) INTRODUCTION: - ASK QUESTIONS ABOUT PREVIOUS LESSON - CORRECT HOMEWORK - IF IT IS THE FIRST LESSON, ASK GENERAL QUESTIONS AND DISCUSS TOPIC OR USE KWL GRID. (5 MIN) 2) GLOSSARY EXERCISE: - MATCHING AND GAP FILL (5-10 MIN) 3) SHORT LECTURE: - ABOUT TOPIC USING POWERPOINT (15 MIN) 4) GROUP WORK WITH ACTIVITIES ON TOPIC (20 MIN) 5) VIDEO OR TEXT ON TOPIC WITH ACTIVITIES (10 MIN) 6) ASSIGN HOMEWORK : ACTIVITIES AND EXERCISES AND / OR ORIGINAL TEXT TO READ ON TOPIC

  6. 1) INTRODUCTION INITIAL ACTIVITIES TO START A LESSON LAST LESSON… Discuss with studentswhattheylearnedduring the last lesson, ask to write down atleastthreethingstheylearned. CORRECT HOMEWORK OPENING QUESTIONS Write on the whiteboardthreequestionsabouttopics of the previouslesson: e.g.: one text basedquestion, one questionthatrequiresapplication of studiedtopics and a challengingquestion.

  7. 1) INTRODUCTION KNOW WANT TO KNOW LEARNED INITIAL ACTIVITIES TO START A LESSON ON A NEW TOPIC: KWL GRID

  8. 2) GLOSSARY EXERCISE BEFORE THE PRESENTATION, IT CAN BE USEFUL TO CARRY OUT A GLOSSARY EXERCISE MATCH WORDS WITH THEIR MEANING THEN GAP FILL EXERCISE WITH THE SAME WORD LIST THIS IS BETTER THAN THE USUAL ITALIAN-ENGLISH GLOSSARY AT THE END OF CHAPTER/BOOK

  9. THE MATCHING EXERCISE CAN BE FOLLOWED BY A GAP FILL EXERCISE WHERE THE SAME WORDS ARE USED.

  10. ENGLISH- ITALIAN GLOSSARY: USED ONLY FOR TECHNICAL WORDS

  11. 3) LECTURE ABOUT OHM’S LAW

  12. LESSONSTRUCTURE

  13. OHM’S LAW

  14. LEYDA JAR IT WAS USED IN THE 18TH CENTURY TO GENERATE SHORT SPARKS TODAY WE KNOW THAT IT IS A CAPACITOR, NOT A BATTERY

  15. VOLTA’S BATTERY VOLTA’S BATTERY (OR PILE) CONSISTS OF TWO ELECTRODES, ONE MADE OF COPPER AND THE OTHER ONE MADE OF ZINC THE ELECTRODES ARE IMMERSED IN AN ELECTROLYTE (SULFURIC ACID)

  16. VOLTA’S BATTERY • - THE BATTERY CAN KEEP A CONSTANT POTENTIAL • DIFFERENCE BETWEEN THE ELECTRODES EVEN WHEN THERY ARE • CONNECTED BY A WIRE • THE POTENTIAL DIFFERENCE REMAINS CONSTANT BECAUSE OF • CHEMICAL REACTIONS TAKING PLACE INSIDE THE BATTERY • IN THE WIRE A DIRECT (I.E. CONSTANT OR STEADY) CURRENT • (DC CURRENT) CAN FLOW FOR A LONG TIME

  17. SIMPLEST CIRCUIT BATTERY SYMBOL USING DIFFERENT BATTERIES WE CAN MEASURE THE CURRENT THAT FLOWS IN DIFFERENT TYPES OF WIRES

  18. CHARGE CARRIERS INSIDE A METAL WIRE ARE ELECTRONS, WHICH ARE NEGATIVELY CHARGED HOWEVER, FOR HISTORICAL REASONS, CURRENTS ARE INDICATED IN CIRCUITS AS IF THEY WERE DUE TO A POSITIVE CHARGE FLOW

  19. WE PLOT CURRENT i ON THE Y-AXIS AND THE POTENTIAL DIFFERENCE V ON THE X-AXIS WE OBTAIN AN i-V CURVE

  20. WE CALL RESISTANCER THE PROPORTIONALITY CONSTANT • THE EQUATION WE OBTAIN IS CALLED OHM’S LAW R EXPERIMENTS SHOW THAT POTENTIAL DIFFERENCE (OR APPLIED VOLTAGE) AND CURRENT ARE DIRECTLY PROPORTIONAL

  21. THE ABOVE EQUATION IS CONSIDERED AS A DEFINITON OF RESISTANCE • RESISTANCE IS MEASURED IN V/A , WHICH IS CALLED OHM (SYMBOL: Ω) WE CAN REWRITE OHM’S LAW IN THE FOLLOWING WAY:

  22. A CIRCUIT ELEMENT THROUGH WHICH A CURRENT FLOWS IS CALLED RESISTOR A NUMBER OR A COLOR CODE INDICATES THE VALUE OF THE RESISTOR IN Ω

  23. OHMIC CONDUCTORS: CONDUCTORS THAT FOLLOW OHM’S LAW • METALS GRAPHITE

  24. NON-OHMIC CONDUCTORS

  25. Diode NON-OHMIC CONDUCTORS Semiconductors Electrolytic cell Light bulb filament RESISTANCE CAN BE COMPUTED ALSO FOR NON-OHMIC CONDUCTORS USING THE FORMULA R=V/I

  26. Example 2 A metal wire carries a current of 1.5 A when a voltage of 220 V is applied to it. If we apply the same potential difference to a piece of wood we measure a current of 40 mA. What is the resistance of the wire? What current flows through the metal wire if we apply a voltage of 400 V? Repeat points a) and b) for the piece of wood.

  27. RESISTIVITY RESISTIVITY DEFINITION RESISTANCE APPLIES TO OBJECTS, RESISTIVITY APPLIES TO MATERIALS

  28. NOTE THAT THE RESISTANCE OF A THIN WIRE IS GREATER THAN THE RESISTANCE OF A THICK WIRE RESISTIVITY IS MEASURED IN Ω∙m SOLVING THE PREVIOUS FORMULA FOR RESISTANCE R WE OBTAIN:

  29. RESISTIVITY VARIES WIDELY IN DIFFERENT MATERIALS

  30. RESISTIVITY CHANGES WITH TEMPERATURE, USUALLY INCREASING THIS IS WHY A LAMP WIRE IS NOT AN OHMIC CONDUCTOR

  31. SUPERCONDUCTIVITY WHEN TEMPERATURE IS CLOSE TO ABSOLUTE ZERO (LIQUID HELIUM), METAL RESISTIVITY DROPS RAPIDLY TO ZERO THIS PHENOMENON CAN ONLY BE EXPLAINED USING QUANTUM MECHANICS

  32. SUPERCONDUCTIVITY TODAY SUPERCONDUCTIVITY HAS BEEN ACHIEVED ALSO AT HIGHER TEMPERATURES (134 K = -139 °C , LIQUID NITROGEN) SUPERCONDUCTING MATERIALS HAVE INTERESTING PROPERTIES THEY CAN LEVITATE INSIDE AN EXTERNAL MAGNETIC FIELD

  33. END OF POWER POINT PRESENTATION

  34. 4) GROUP WORK WITH ACTIVITIES

  35. CLIL ACTIVITIES CLIL ACTIVITIES ARE THE CENTRAL PART OF EVERY CLIL LESSON BIBLIOGRAPHY: • A new planet - Percorsi disciplinari e per il CLIL, Spiazzi M., Tavella M., Zanichelli (2006) • Mathematics, Meyrick C., Roberts J., Oxford (2010) • Clil Activities - A resource for subject and language teachers, Dale L., Tanner R., Cambridge (2012).

  36. CLIL ACTIVITIES CLIL ACTIVITIES MUST TAKE THE ENGLISH LANGUAGE CURRICULUM INTO ACCOUNT (CHECK WITH ENGLISH TEACHER) 2ND GRADE: MODAL VERBS (MUST, CAN , SHOULD , WOULD), CONDITIONAL. 3RD GRADE: REVISION: VERBS, TENSE, CONDITIONALS, COMPARATIVES. 4TH GRADE: PASSIVE/ACTIVE, MODALS OF CERTAINTY, MAKING COMPARISONS, COLLOCATIONS. 5TH GRADE: ACADEMIC WORDS, PARAPHRASE METAPHORS, COLLOCATIONS, PARAGRAPH, CONNECTORS

  37. MATCHING EXERCISES MATCH A WORD WITH ITS MEANING

  38. MATCHING EXERCISES MATCH A PROBLEM WITH THE CORRESPONDING EQUATION AND WITH THE SOLUTION THIS IS A GUIDED APPROACH TO TRADITIONAL PHYSICS PROBLEMS

  39. MATCHING EXERCISES MATCH A WORD WITH ITS DEFINITON

  40. MATCHING EXERCISES MATCH A PHYSICAL LAW WITH ITS CORRECT DEFINITION

  41. MATCHING EXERCISES MATCH A COLOUR WITH ITS WAVELENGTH/FREQUENCY

  42. MATCHING EXERCISES MATCH LAMP TYPE WITH COLOUR TEMPERATURE

  43. MATCHING EXERCISES MATCH THE BEGINNING OF A SENTENCE WITH ITS END

  44. MATCHING EXERCISES MATCH A QUESTION WITH ITS ANSWER

  45. MATCHING EXERCISES MATCH A WORD WITH A PICTURE

  46. GAP FILL EXERCISES
