Geography

Grade 4

Map work

Map symbols

Module 5

A large area is usually shown in a small picture on a map. Numbers, letters and pictures are then used to indicate rivers, roads, railway lines, buildings, etc. They are called map symbols. To explain the symbols on a map, a symbol key is used.

1.the plan (map) of my classroom

Tom has drawn a map (plan) of his classroom:

Tom’s classroom

Scale: 1 square = 1 step

The classroom was too big to be drawn on a sheet of paper, and TOM had to REDUCE the classroom. For each step that he took, he used one square on the paper. The tables and other items were also reduced in the same way.

Activity 1

To draw a plan of the classroom [lo 1.3]

Use the symbol key given and draw a plan of your classroom as you think it will look from the air. You can add to the key if you want to. You can use colour, but work in pencil first to plan it. Use one step for each square. Work on your own.

My classroom

Key

That looks very nice!

Your educator will now give you a plan of your classroom that he/she has drawn up.

Activity 2

To compare two plans with one another [lo 1.3]

1. Compare your educator’s plan with the one that you drew for your classroom. Check to see where you made mistakes.

2. Measure the length of the classroom in steps. It is steps long.

3. Measure the width of the classroom in steps. It is steps wide.

  1. Colour your desk red.
  2. Draw the shortest route to the door of the classroom with a red arrow.

2.a plan of the school grounds

  • Today we are going to study a bigger plan. We are going to represent the ENTIRE SCHOOL GROUNDS on a plan (map).
  • However, we must first do FIELDWORK to gather all the knowledge required.

Activity 3

To represent the school grounds on a plan [lo 1.4]

Take a piece of paper and a pencil with you to make notes and sketches of everything you see. Look carefully at the following:

1. The location and shape of the school building.

2. The location and shape of other buildings on the school grounds.

3. The location and shape of the sports fields.

4. The location and shape of the playing fields.

5. The location and shape of the flower gardens.

6. The location of the main entrance gate.

7. The names of the streets on all sides of the school grounds.

8. Make sure where the four main directions are located.

Back in the classroom

Your educator will now hand out a completed plan of the school grounds:

1. Turn your desks so that you all face NORTH.

2. Study the plan of the school grounds carefully and decide where the four main directions are. Indicate these on the plan.

3. Study the plan of the school grounds carefully and compare it with your notes. Do you agree with the location of the buildings and other objects?

4. Use the key to your plan and colour in the plan accordingly: Example: school buildings – red sports fields - green

5. If you have a problem, your educator can take you outside again to make sure of your facts.

6. Indicate the route from your classroom to the principal’s office with a red arrow.

7. In what direction does the front door of your school face?

8. Write down the names of the various streets around the school in the correct places on the plan.

3. Our immediate surroundings

  • This is a street plan of a portion of Cape Town

Activity 4

To read a street plan [lo 1.5]

1. Why do we need a street plan of a city?

……………………………………………………………………………………….

……………………………………………………………………………………….

2. In what direction does building A lie from building C?

……………………………………………………………………………………….

3. Use red to indicate the shortest route from point C to point D on the map (take one-way streets into consideration).

4. You are standing on the corner of Loop and Leeuwen Streets. Explain to a tourist how to get from that position to point D.

………………………………………………………………………………………

………………………………………………………………………………………

………………………………………………………………………………………

Your educator will later give you a map just like this one of your own environment. However, today we are first going to do FIELDWORK again in our own environment.

Your educator will now give each of you a map of your immediate environment. Answer the following questions (note the key to the map):

1. Find your school on the street plan and colour it in.

2. Find your own home, or that of someone you know well, on the map. Colour it in with a different colour.

3. Indicate the route that you followed on your fieldwork outing on the map.

4. Which street is south of your school? ……………………………….

5. Indicate on your own map the important buildings and other features that your educator pointed out during the outing.

Assessment

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];

1.5 identifies important political boundaries and key human and physical features on large-scale maps [works with sources].

Memorandum

  1. Not to get lost

To find places

To find the shortest routes

  1. S

4. 2 blocks east (in Leeuwen)

2 blocks south

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?

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

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?

not now but maybe in future only AgNP maybe any other nanomaterials

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?
