Maak ‘n kissie van klei

Toepassing van verworwe kennis in tegnologiese proses

Kom ons maak ‘n kissie van klei.

Gevallestudie vir ‘n seun

Jy speel elke pouse albaster by die skool en is al baie vaardig. Elke dag wen jy pragtige ghoens wat jy met groot trots elke middag tuis vir jou pa gaan wys. Hierdie ghoens neem jy nie weer skool toe nie, want jy is bang dat jy hulle gaan verloor. Ongelukkig vergeet jy om hulle tuis op ‘n veilige plek te bêre. Vanmiddag het Ma jou vir die derde agtereenvolgende dag berispe omdat jou nuwe albasters in jou skoolbroek se sakke vergete gebly het en hulle in die wasmasjien beland het. Jou ma is baie verleë, want sy moes weer die loodgieter laat kom. Sy vermaan jou om ‘n houer vir jou albasters te kry, anders sou sy hulle stilletjies laat verdwyn. Jy besluit dat hierdie houer nie sommer ‘n leë plastieksak, ‘n glas grondboontjie-botterfles of ‘n leë koffieblik gaan wees nie.

Gevallestudie vir ‘n dogter

Dis klaar moeilik om vroeg op te staan vir skool tydens die winter, maar as ‘n mens se haarrekkies pal op soek is, veral wanneer jy reeds laat is, is dit nodig om ‘n plan te maak, want jy verpas gereeld die skoolbus en dan moet Ma jou met die ou plaasbakkie skool toe neem. Jy gaan vir jou ‘n houer ontwerp en maak. Dan kan jy dit op jou spieëltafel by jou borsel sit en jou haarrekkies daarin plaas die oomblik as jy hulle uit jou hare haal. Julle het nie verniet ‘n groot dam op die plaas waar daar baie klei is nie. Jy wil ‘n houer van klei maak.

1. Navorsing

OPDRAG 1:

a) Wat is die behoefte?

b) Skryf nou ‘n duidelike en kort ontwerpvoorstel neer vir die maak van jou produk.

Ek gaan ‘n ( wat ) ontwerp en maak om by die ( waar )

te gebruik, sodat ek my ( wat )

daarin kan bêre.

LU/AS 1.4

c) Spesifikasies vir die ontwerp en vervaardiging.

SPESIFIKASIES VIR DIE ONTWERP EN VERVAARDIGING
1. Die vorm/fatsoen ‘n Kubus met ‘n los deksel
2 Die grootte Sye van ± 10 cm elk met kante 5 mm dik
3 Materiale gebruik Modelleerklei
4 Afwerking Kreatiewe patrone op buitekant aangebring
5 Duursaamheid Hanteer versigtig, want dit kan breek
6 Veiligheid Hanteer kleimes versigtig

2. Ontwerp

Agtergrond

Die vyf beginsels vir ‘n geslaagde ontwerp is dat die produk ‘n DOEL moet hê, ‘n interessante VOORKOMS sal hê, van gepaste MATERIAAL gemaak sal wees, stewig en sterk VERVAARDIG sal wees en dat dit ‘n positiewe INVLOED op die gebruiker en omgewing sal hê.

OPDRAG 2A:

Ontwerp die houer vir jou haarrekkies/albasters deur ‘n isometriese tekening van die houer sonder deksel te maak. Teken ‘n klomp ontwerpe.

LU/AS 1.5

OPDRAG 2B:

Omkring die beste idee. Onthou ook byskrifte.

LU/AS 1.6

Vereistes

Jy gaan ses los teëls maak wat jy aanmekaar kan heg. Jy moet die buitekant van die houer op ‘n kreatiewe en oorspronklike manier versier deur voorwerpies soos skroewe, naalde en skuifspelde in die sagte klei te druk of deur patrone met ‘n sosatiestokkie daarop aan te bring. Jy gaan nie die horisontale vlak wat die bodem vorm, versier nie en ook nie die deksel nie. Dus gaan jy net die vier vertikale vlakke op dieselfde manier versier.

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?
