Assessment

Memorandum

ACTIVITY1:

1. L × B

(5,6 × 0,5) × (3,4 × 0,5)

2,8 × 1,7

= 4,76 km ²

• L × B

(1,1 × 500) × (0,6 × 500)

550 × 300

165 000 m ²

ACTIVITY 2:

Distance Speed 1. Actual distance = 8 × 0,5 = 4 km

Time =

= $\frac{4\text{km}}{\text{80}\text{km}/h}$

= 0,05 × 60

= 3 minutes

• 7:00 + 3 minutes

= 7:03

ACTIVITY 3:

1. 29 ⁰ 08’ S, 26 ⁰ 15’E
2. Free State
3. ESE
4. ± 70 km
5. Time = $\frac{\text{Distance}}{\text{Speed}}$

= $\frac{\text{70}\text{km}}{\text{120}\text{km}/h}$

= 0,583 × 60

= 34,98 minutes

• 10:00 + 34,88 = 10:34,98
• Origin of Bloemfontein

1. People who migrated from the Cape settled there.
2. In 1846 Major Warden chose it as a suitable place to build a fort and settlement.

Development of Bloemfontein

• Initially it quickly developed into a trading centre.
• Wars and insurrection did not halt the growth.
• Geographic centre of rail, road and air transport.
• Gold-fields 160 km away boost growth.
• Today an important industrial centre.
• Tourism is flourishing thanks to picturesque surroundings.

ACTIVITY 4:

1a) Pointed hill

b) Flat-topped hill (Naval Hill)

3a) 2826 CC

b) 2925 BB

c) 2926 AC

4.

5a) Topographical map = 1:50 000

Orthophoto = 1:10 000

b) Topographical 1:50 000 is a smaller scale

• Motor or motorcycle racing, camping in caravan park, golfing, hang-gliding, flying aeroplanes, visiting zoo, visiting parks, visiting botanical gardens, playing sports on sports fields, swimming in rivers and dams, sailing on dams, visiting observatory, etc.
• Windmills are used to retrieve underground water for consumption. Therefore it must be relatively dry here with intermittent rainfall.

8 (a)

1. Winter
2. January

ACTIVITY 5:

1. Highest point 1499

Co-ordinates: 29 ⁰ 05’ 50” S 26 ⁰ 13’ 20’ E

1. Higher, flat area from where there is a good view.

City lights and pollution have smaller effect here.

3. True North / Bearing : 164 ⁰

Magnetic Declination : 2001 – 2003 = 2 years

2 × 6’ westwards (+)

20 ⁰ 35’ + 12’

= 20 ⁰ 35’ west of true north

Magnetic Bearing = 640 + 20 ⁰ 35’

= 184 ⁰ 35’

4. Map distance = 8,5 cm × 0,5 = 4,25 km

Time = $\frac{\text{Distance}}{\text{Speed}}$

= $\frac{\mathrm{4,}\text{25}\text{km}}{\text{120}\text{km}/h}$

= 0,35 × 60

= 2,1 minutes

1. L × B

(0,9 × 500) × (0,5 × 500)

450 × 250

= 112 500m ²

6. Actual bearing = 266 ⁰

ACTIVITY 6:

1. Vertical
2. Learners do on map
3. Actual distance = 26,6 cm on a 1:10 000 map

26,6 × 0,1

= 2,66 km

1. North-east
2. Defence Force training centre

Many soldiers who live in barracks

6.a) South-east

b) Afternoons

ACTIVITY 7:

In order for a poster to catch the eye, it must be easy to read.

Make use of photos, sketches, etc. and limit the text to a minimum by listing only the most important facts.
