Grade 8


Module 37


Activity 1:

To be able to explain the value of eco-tourism and to develop a product that can be used to inspire others

[lo 1.1; lo 1.2; lo 1.3; lo 3.2]

Ecotourism refers to an industry that encourages tourists to experience and appreciate the country’s natural beauty and ecologically pristine areas.

South Africa is the only country on earth in which all the members of a specific plant kingdom are found naturally within its borders. This plant kingdom is the FYNBOS of the Western Cape.

It is an area that stretches around the mountains of the Boland, and includes various unique plant species such as the protea (our national flower) and heather. It has the greatest concentration of endemic plant species. Endemic means that it does not occur naturally anywhere else.

St Lucia and other marshlands are the birthplace of many species. These areas have a very delicate balance which can easily be disturbed by 4x4 enthusiasts and pleasure boat adventurers.

One reads news articles about these and other sensitive areas all the time. Unfortunately there are constantly reports about insensitive people who do not know how to utilize, appreciate and conserve these precious areas.

Our game parks such as the Kruger National Park, the Kgalagadi, Hluhluwe and Pilanesberg are widely known amongst overseas tourists.

NATURE CONSERVATION is of the utmost importance in all these areas. Strict rules apply and are generally adhered to by considerate tourists.

  • Design a colourful brochure that you could give to a tourist from overseas in order to introduce them to the natural beauty of South Africa, and its ecological treasures.
  • You may choose one or more topics.
  • You will have to research the natural beauty, sensitivity and uniqueness (plants and animals) of a specific environment and incorporate the findings in the brochure.
  • Hand the brochure in on the date that has been determined by your teacher.

Alternatively: Compile a video clip or photo album of such a natural area and show it to the class.

Assessment of the BROCHURE: Were you able to PLAN and CONDENSE FACTS in a visual presentation? [LO 1.1; LO 1.2; LO 1.3]

  • Now write 270 words on the value of ecotourism. Refer to your research.

[ LO 3.2]


LO 1: Scientific investigations:

The learner will be able to act confidently on curiosity about natural phenomena, and to investigate relationships and solve problems in scientific, technological and environmental contexts.

This is evident when the learner:

  • plans investigations;
  • conducts investigations and collects data;
  • evaluates data and communicates findings.

LO 3: Science, Society and the Environment

The learner will be able to demonstrate an understanding of the interrelationships between science and technology, society and the environment.

This is evident when the learner:

3.2 understands sustainable use of the earth’s resources.


Activity 1: Brochure or video

  • Learners are required to design a colourful brochure that could be given to a tourist from abroad to introduce the natural beauty of South Africa as well as the country's ecological treasures. The learner may choose one or two subjects.
  • Assess this in conjunction with the paragraph on the value of ecotourism. Note the following:
  • Problem statement (planning)
  • Sources used for information
  • Quality of information (did the learner make a selection or simply accept what was found first?)
  • Layout / presentation / reasoning (communicating).

hmm well what is the answer
how do they get the third part x = (32)5/4

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

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

abeetha Reply
I start with an easy one. carbon nanotubes woven into a long filament like a string
many many of nanotubes
what is the k.e before it land
what is the function of carbon nanotubes?
I'm interested in nanotube
what is nanomaterials​ and their applications of sensors.

what is system testing?
preparation of nanomaterial
Victor Reply
Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
Himanshu Reply
good afternoon madam
what is system testing
what is the application of nanotechnology?
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
anybody can imagine what will be happen after 100 years from now in nano tech world
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
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
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?
