Opvoeders afdeling

Memorandum

Die module is opgestel volgens die Leeruitkomstes en Assesseringstandaarde soos vervat in die dokument, uitgegee deur die Nasionale Onderwysraad.

Die take en aktiwiteite is in lyn met die kurrikulum, maar dit kan nie die taak van die opvoeder, om te onderrig, vervang nie. Nuwe begrippe moet eers konkreet en deeglik onderrig word, voordat die take vir die leerder van enige nut kan wees.

Hierdie aktiwiteite kan gebruik word vir toepassing, konsolidering, vaslegging, verryking en assessering van werk wat vooraf onderrig is.

Onderaan elke bladsy van die leerders, verskyn die nommer van die leeruitkoms wat op die betrokke bladsy ter sprake is. Die nommers is in ooreenstemming met dié van die raamwerk voor in elke leereenheid. Hierby is ook ‘n ruit, vir onmiddellike assessering, aangebring. Aan die einde van die module verskyn die assesseringsruit waar ‘n gemiddelde punt vir die betrokke module bereken en aangedui kan word.

Dit mag wees dat die “vinnige” leerders baie vinnig deur ‘n module sal gaan, in watter geval van soortgelyke aktiwiteite gebruik gemaak kan word. Dit is dus dringend noodsaaklik dat die opvoeder deeglik bewus sal wees van die inhoud van elke taak, alvorens dit aan die leerders gegee word.

Sommige opdragte en take vereis ook vooraf beplanning deur die opvoeder . Om die taak van die opvoeder te vergemaklik, is daar inligting op die bladsye genommer O - 1 tot O - 7 aangeheg. Hierdie bladsye word nie aan die leerders uitgedeel nie.

Die opvoeder moet die leerders help om die inligting van hul verjaardae in die klas te bekom sodat hulle die blokgrafiek kan voltooi.

Laat die leerders hulle hande opsteek in die maand waarin hulle verjaar en tel dan hoeveel daar in elke maand is. Hierdie inligting skryf die leerder dan in die sirkel bokant elke maand,

bv. 3 kinders verjaar in Januarie. Die 3 word in die sirkel reg bokant Jan . geskryf.

Hierdie taak kan al die leerders gelyktydig doen.

Dit is ook ‘n goeie geleentheid om nou die name van die maande in die regte volgorde aan te leer. Dit is nie nodig dat hulle dit in hierdie stadium moet kan skryf nie.

Gee die leerders genoeg tyd om hul bevindings, afleidings en gevolgtrekkings na die voltooiing van die blokgrafiek te bespreek.

Wanneer met bewerkings begin word, sal dit goed wees om die leerders bewus te maak dat die 4 bewerkings (optel, vermenigvuldig, aftrek en deel) slegs 2 verskillende prosesse behels:

Kyk na Hoe meer die leerder hierdie voorstelling sien en die verduideliking hoor , hoe beter sal hy dit begryp en kan toepas by die oplossing van probleme.

Die leerders moet die kommutatiewe eienskap van optelling ( 3 + 4 = 7 en4 + 3 = 7 ) en vermenigvuldiging ( 2 x 5 = 10 en 5 x 2 = 10 ) verstaan, maar hy hoef nie die woorde “ kommutatiewe eienskap ” te ken of te gebruik nie.

Die leerder moet die assosiatiewe eienskap van aftrekking(9 – 4 = 5 en 9 - 5 = 4 ) en deling ( 10  2 = 5 en 10  5 = 2 ) verstaan.

Leerders moet eers met konkrete voorwerpe ervaar hoe die antwoorde van die aftrekbewerkings getoets kan word: bring terug wat jy weggeneem het en as jy weer die getal waarmee jy begin het, kry, dan weet jy dit is reg.

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone

how do lnternal energy measures

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.
Dlovan
Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
