Memorandum

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;

3. hulself en hul aktiwiteite verantwoordelik en doeltreffend bestuur;

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;

10. in verskeie sosiale kontekste kultureel en esteties sensitief te wees;

11. opvoedings- en lberoepsmoontlikhede ondersoek; en

12. entrepreneursgeleenthede te ontwikkel.

Integrasie van Temas:

  • Inklusiwiteit: Ons kan almal by mekaar leer. Die een kultuur kan die ander stimuleer en verryk. Wys hoe dit gedoen kan word.
  • Menseregte: Leerders moet die verskille tussen hulle respekteer. Besluit hoe ons verskil en wat ons verskillend maak. Tog is elkeen net so menswaardig soos enige ander leerder in die klas.
  • ‘n Gesonde omgewing: Blomme verryk ons omgewing. Gesonde kos gee vir ons gesonde liggame. Bespreek gesonde, voedsame kossoorte en maak ‘n lys daarvan. Doen navorsing om vas te stel of die leerders in jou klas gesonde kosse eet.
  • Getalbegrip en aantel tot 200 en verder word geoefen.
  • Ewe en onewe getalle, afronding van getalle en plekwaardes word hersien.
  • Die tafels van 4 en 3 en deelaktiwiteite word ingesluit.
  • Optelling met herbenoeming word geoefen.
  • Verdubbeling met herbenoeming.
  • Samestellings van 19.
  • Die volgende aktiwiteite is ook ingesluit: massa, inhoud, breuke en afstand.
  • Leerders maak kennis met die volgende voorwerpe: piramides, prismas en silinders,
  • Die aansigvorms van hierdie 3-D vorms word bespreek en vergelyk.

Assessering

Leeruitkomste 1: Die leerder is in staat om getalle en die verwantskappe daarvan te herken, te beskryf en voor te stel, en om tydens probleemoplossing bevoeg en met selfvertroue te tel, te skat, te bereken en te kontroleer.

Assesseringstandaard 1.5: Dit is duidelik wanneer die leerder die plekwaarde van syfers in heelgetalle tot minstens 2-syfergetalle herken;

Assesseringstandaard 1.6: Dit is duidelik wanneer die leerder geldprobleme oplos wat totale en kleingeld in rand en sent behels;

Assesseringstandaard 1.8: Dit is duidelik wanneer die leerder die gepaste simbole in berekeninge gebruik om probleme op te los:

Assesseringstandaard 1.10: Dit is duidelik wanneer die leerder die volgende tegnieke gebruik:

1.10.1 opbou en afbreek van getalle;

1.10.2 verdubbeling en halvering;

1.10.3 gebruik van konkrete apparaat (bv. tellers);

1.10.4 getallelyne.

Questions & Answers

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?
ninjadapaul

algebra 2 Inequalities:If equation 2 = 0 it is an open set?
Kim Reply
or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
Azam
anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
Ali Reply
the Beer law works very well for dilute solutions but fails for very high concentrations. why?
