Die geheimsinnige see

Die geheimsinnige see

Ons praat van die wêreld waarin ons leef as die “aarde.” Eintlik is dit verkeerd, want daar is baie meer water as vasteland (mainland). As ons die wêreld sou verdeel in see en vasteland, sal daar 70% see en 30% vasteland wees. As die sirkel hieronder die aarde voorstel, hoe kan jy dit verdeel om aan te dui watter persentasie is water en watter persentasie is vasteland?

Duisende jare gelede het die mense net die land geken en byna niks geweet van die wye en geheimsinnige oseaan nie. Die land was al wat belangrik was. Ons kan dit sien op hierdie “Wêreldkaart” wat 2 500 jaar gelede geteken is deur ‘n Griekse geleerde, Hekatäus. Hierdie kaart stel die aarde voor as Europa, Asië en Noord-Afrika en die Middellandse See.

Die wêreldkaart van die Griekse geleerde Hekatäus (ongeveer 500 v.C.)

Die wêreldkaart vandag

Verdeel nou in groepe en bespreek die volgende:

Wat is die grootste verskille tussen die twee kaarte?

  • Hoeveel vastelande is daar op ons wêreldkaart?
  • Watter lande kan julle herken op Hekatäus se kaart?
  • Wat is hulle name?
  • Hoekom word die Middellandse See so genoem?
  • Wat is die Griekse naam vir die oseaan?

Seediere

Die see is die tuiste van talle plante en diere. Die meeste seediere kom in die kuswaters naby die land voor. Kan jy enige van die volgende herken? Werk saam met ‘n maat en skryf die name neer van die seediere wat julle herken. Kies uit die lys hieronder.

seeperdjie; kreef; haai; rob; dolfyn; paling; pikkewyn; walvis:

LU 6.1.2

Leer nou die spelling van hierdie seediere se name.

Mondeling

Jy het nou ‘n gesprek tussen ‘n haai en ‘n duiwelvuurvis ontsyfer. Hier gaan nou nog ‘n gesprek volg, maar hierdie slag is jy ook ‘n vis. Jy kan enige vis of seedier wees. Jou maat gaan die onderstaande vrae vra en jy moet hulle kan beantwoord. Jy sal dus ‘n bietjie inligting moet insamel oor die vis of seedier wat jy wil wees. Jy en jou maat gaan beurte maak om die vrae te stel. Ons kan mos ook sê julle gaan beurte maak om ‘n onderhoud te voer. Onthou om in volsinne te antwoord.

ONDERHOUD

Julle kan die antwoorde neerskryf as julle wil.

  1. Wat is jou naam? (Watter soort seedier of vis is jy?)
  1. Beskryf hoe jy lyk:
  1. Waar of wat is jou woonplek?
  1. Wat eet jy en hoe kry jy jou kos in die hande?
  1. Wie of wat is jou vyande en hoekom?
  1. Hoe plant jy voort? (How do you reproduce?)
  1. Hoe beweeg jy?
  1. Het jy enige eienaardige gewoontes? (Do you have any strange habits?) Vertel ons daarvan.
LU 2.1.1
LU 2.3.6

ASSESSERING: MONDELING – onderhoud voer

Skriftelike werk

Skryf nou ‘n kort verslag oor die seedier of vis waaroor jy gepraat het. Beskryf dieselfde dinge soos wat jy dit gedoen het terwyl jy mondeling gepraat het.

  • watter soort seedier of vis jy is;
  • jou voorkoms;
  • jou woonplek;
  • jou kos;
  • jou vyande;
  • waar jy jou eiers lê;
  • hoe jy beweeg;
  • enige eienaardige gewoontes

Skryf ongeveer ag tot tien sinne. Die titel moet die naam van jou vis of seedier wees.

LU 4.1.3

Stilleestoets

Lees die onderstaande leesstuk oor visse se uitwendige kenmerke. Beantwoord die vrae.

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

or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

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.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
