# 1.5 A grid network

 Page 1 / 1

## A grid network

• To indicate the location of a specific place or characteristic is much easier if there is a grid network. These are lines drawn on the map, which divide the map into small squares. At the top of the map, each square is then numbered 1, 2, 3, and so on. In the left and/or right margins, you find the letters A, B, C, etc.

We then use these letters and numbers to give each square a name.

Example:

 1 2 3 A A B B C C 3 2 3

If now you want to indicate where the aeroplane is, we say it is in block B2 .

## To indicate location by means of a grid network [lo 1.3, 1.4]

Indicate the location of the following objects as they appear in the example:

1. man …………………………………………………………………………………

2. tree …………………………………………………………………………………

3. dog ………………………………………………………………………………….

4. house ………………………………………………………………………………

Study this grid:

 1 2 3 4 5 A e n r g l A B j q b t p B C w k v x d C D c y o I v D E h m f s a E 1 2 3 4 5

Now study the following coded message that has been written according to the grid network code and decipher it. A semi-colon (;) indicates the end of a word.

D4; A5 D4 D5 A1; D4 A2; D1 E5 B5 A1; B4 D3 C1 A2; C1 E1 A1 A3 A1; C5 D3; D2 D3 B2; A5 D4 D5 A1

Now write your own secret message by using the grid network code. Swap your secret message with a classmate and decipher each other’s messages.

## Learning outcome 1: geographical enquiry

The learner will be able to use enquiry skills to investigate geographical and

environmental concepts and processes.

## Assessment standard

We know this when the learner:

1.3 identifies symbols used in different kinds of maps (including plan view, grids and map keys) [works with sources].

1.4 locates places using a simple grid referencing system and directions [works with sources].

what are the products of Nano chemistry?
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
learn
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level
learn
da
no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts

ya I also want to know the raman spectra
Bhagvanji
I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think
Professor
Nasa has use it in the 60's, copper as water purification in the moon travel.
Alexandre
nanocopper obvius
Alexandre
what is the stm
is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
Damian
How we are making nano material?
what is a peer
What is meant by 'nano scale'?
What is STMs full form?
LITNING
scanning tunneling microscope
Sahil
how nano science is used for hydrophobicity
Santosh
Do u think that Graphene and Fullrene fiber can be used to make Air Plane body structure the lightest and strongest. Rafiq
Rafiq
what is differents between GO and RGO?
Mahi
what is simplest way to understand the applications of nano robots used to detect the cancer affected cell of human body.? How this robot is carried to required site of body cell.? what will be the carrier material and how can be detected that correct delivery of drug is done Rafiq
Rafiq
if virus is killing to make ARTIFICIAL DNA OF GRAPHENE FOR KILLED THE VIRUS .THIS IS OUR ASSUMPTION
Anam
analytical skills graphene is prepared to kill any type viruses .
Anam
Any one who tell me about Preparation and application of Nanomaterial for drug Delivery
Hafiz
what is Nano technology ?
write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
