Kritieke- en ontwikkelings uitkomste

Die leerders moet uiteindelik kan:

1. probleme identifiseer en oplos, en ook besluite neem deur kritiese en kreatiewe denke;

2. doeltreffend saam met ander lede van ‘n span, groep, organisasie en gemeenskap werk;

4. inligting versamel, ontleed, organiseer en krities evalueer;

5. doeltreffend kommunikeer deur middel van visuele, simboliese en/of taalvaardighede in verskillende vorme;

6. wetenskap en tegnologie doeltreffend en krities gebruik deur verantwoordelikheid teenoor die omgewing en die gesondheid van ander te toon;

7. begryp dat die wêreld ‘n stel verwante stelsels is waarin probleme nie in isolasie opgelos word nie;

8. na te dink oor en ondersoek te doen na ‘n verskeidenheid strategieë om doeltreffender te leer;

9. as verantwoordelike burgers aan die lewe van die plaaslike, nasionale en wêreldgemeenskap deel te neem;

  • ‘n Gesonde Omgewing: Tekens van Herfs.
  • Die module begin met ‘n grafiek van die verjaarsdae van hulle vriende.
  • Getalbegrip en telaktiwiteite word uitgebrei tot 120, met klem op telpatrone.
  • Halvering en verdubbeling in die getalgebied 1 tot 50.
  • Inkopie-aktiwiteite sluit in woordsomme, rigtingaanwysings na winkels en die selektering van die korrekte muntstukke.
  • Leerders voltooi ‘n inkopie-grafiek.
  • Samestellings van 10, 11, 12, 13, 14 en 15 word bekend gestel en met ‘n wye verskeidenheid aktiwiteite vasgelê.
  • Meetaktiwiteite versterk die woordeskat van ‘n “klein massa” en ‘n “groot massa”, gram en kilogram.
  • ‘n Resep vir muffins word ingesluit en die leerders kry praktiese ervaring van meting (Tegnologie).
  • Deur gebruik te maak van patrone op hutte, ontwerp die leerders hulle eie patrone om sodoende hulle sensitiwiteit vir ander kulture te bevorder.
  • ‘n Geheue-speletjie is ingesluit om leerders te help om getalsinne te bemeester.

can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Joseph Reply
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing
