Geography

Grade 5

Resources

Module 16

Natural resources: plants

Make use of what you have learnt previously to try to complete the following definition concerning NATURAL RESOURCES.

People need natural resources such as plants,......................................,

soil, ........................................... and water to survive. All of this is obtained from

nature. Examples of fossil fuels are gas and coal while minerals such as salt, rocks, gold, silver, iron and calcium are formed in the earth by nature.

Activity 1:

To identify resources

[lo 1.3]

Study the sketch of a production line for the manufacturing of cars and list the natural resources that you think may be necessary for the production of a modern motor vehicle.

Natural resources:

Are you able to think of other resources besides natural resources that are also

utilised in the production of cars? (Take another look at the sketch on page 1.)

Utilisation of natural resources by our predecessors

Our predecessors and the people of early civilisations were very aware of their dependence on natural resources. From the earliest times, people settled where they had access to food and water. They lived as nomads, wandering around in search of grazing, food and water. In time they became farmers and settled down for longer periods of time in places where the natural resources were adequate. Eventually people discovered mineral resources, e.g. iron and copper. This made it possible to produce objects for adorning themselves and for domestic wares, as well as weapons like arrowheads that helped them to hunt animals for food and defend themselves against their enemies.

Although we are less aware of our dependence on natural resources, we do need many different resources for our survival.

  1. Plants as a natural resource

Activity 2:

To listen to the uses of natural resources

[lo 1.2; 1.3]

Competition time! See who is able to draw up the longest list of uses of plants as a natural resource .

Forestry as a natural resource

Forestry is the important resource that enables you to write and communicate successfully day after day. For this, thousands of trees are felled every day, merely to produce enough paper to produce daily newspapers. Although people plant plantations, they are better suited to some climatic regions than to others and are therefore spread out across the country.

Forestry in South Africa and Namibia

Activity 3:

To investigate products that are derived from wood

[lo 1.1]

  • Investigate every room in the school through which you move and make a list of all the products/articles that are made of wood.

Assessment

LO 1

GEOGRAPHICAL ENQUIRY

The learner will be able to use enquiry skills to investigate geographical and environmental concepts and processes.

We know this when the learner:

1.1 with guidance, selects and uses sources of useful geographical information [finds sources];

  • distinguishes between facts and opinions [works with sources];
  • categorises information [works with sources];
  • uses an index to find places on global atlas maps [works with sources];

1.6 identifies and explores possible solutions to problems [answers the question];

1.7 demonstrates knowledge and under-standing of the issue through projects, discussion, debate and charts [communicates the answer].

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
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
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?
