Gender stereotypes associated with career choices and entrepreneurial opportunities in social studies

Gender is the state of being male or female in relation to social and cultural roles.

Stereotypes are fixed general ideas or images that assume that a person behaves in a particular way.

Stereotypes limit aspirations and development of talents.

They create gender differences.

These gender differences ought to be addressed using appropriate strategies.

A strategy is a careful plan or method of dealing with an issue

We can address gender stereotypes in career and entrepreneurial opportunities related to social studies through the following strategies

  1. Committing and encouraging both males and females to take a full range of careers and business opportunities
  2. Ensuring representation of both genders in leadership
  3. Treating both males and females equally by using texts and circular that does not promote gender bias
  4. Develop policies, law and decision making process that represent both males and females

Recognising biological difference devoid of stereotypes in career choices and entrepreneurial opportunities in social studies

  • There are biological differences between male and female people.
  • Biological difference should never be a hindrance to one’s career choice and entrepreneurial opportunities
  • Both male and female should be given equal opportunities to pursue their dreams

Demonstrating respect for one’s gender identity in pursuit of social studies careers and entrepreneurial opportunities

Locating places and features on a map using latitudes and longitudes

  • When giving the position of a place or features we with start with the latitude and then longitude

Major latitudes and longitudes

  • Major longitude is called prime meridian also called Greenwich meridian
  • In Africa it passes through:
  • Ghana(Accra)
  • Algeria
  • Burkina faso
  • Mali
  • All other longitudes are measured and named from prime meridian up to 180  ̊ on both sides
  • Major latitude are 3 passing through Africa
  • Equator 0  ̊  – divides Africa into two parts

                         It passes through;

  1. Gabon
  2. Congo
  3. DR congo
  4. Uganda
  5. Kenya

Calculating the time of different places in the world using longitudes

  • Rotation of the earth- This is movement of earth on its own axis
  • Distance between longitudes is measured in degrees
  • There are 360 meridians or longitudes
  • One complete rotation is 360 ̊
  • The direction of the rotation is from west to east i.e. anticlockwise direction.
  • One complete rotation takes 24 hours
  • All places found in the east of the Greenwich meridian will see sunrise first and therefore they are one hour ahead of those to the west

Effects of rotation of the earth

  1. Differences in time along different longitudes
  2. Occurrence of day and night

24hrs = 360 ̊

1hr = ?

360×1 ÷24 =15

Therefore 1hr =15 ̊   or 360  ̊= (24×60)minutes=1440min

̊= 1440÷360 ×1=4min

I Hr the earth covers 15º and 1º it covers 4 minutes

Calculating time of places found to the east of Greenwich Meridian

Example 1

The time in Accra 0 ̊ is 7.00am.calculate time in bermbera 45  ̊E

1hr =15  ̊

?    = 45  ̊ = 45÷15×1 =3hrs

So 3hrs is equivalent to 45  ̊ then add 3hrs   to 7.00am to get 10.00am

Example 2

Suppose the time at GWM is 12 noon what is the local time at Watamu 40◦E?

Time gained=40×4=160min=2 hours 40min

Local time at Watamu is 12.00+2.40=14.40-1200=2.40pm.

Example 3

At Dar-es-Salaam 40◦E time is 12pm what is the time at Ecuador 40◦E?

40◦+20◦=60◦

60×4=240min=4hours

Ecuador is behind in time =12.00-4=8 am.

NB

  • When calculating time to the east of Greenwich meridian, we add the time difference to the local time.

Calculating time of places found to the west of Greenwich Meridian

  • When calculating time to the west of Greenwich meridian we subtract the time difference to the local time

Example 1

A plane leaves off in New York, 74ºW at 7 am local time. What is the local time in Stockholm 18ºE

NB

  • If the places are on the same side subtract the degrees to get the difference and add or subtract from the reference time depending on which side the place is.

Types of maps

  1. Topographical maps ­

This shows selected natural physical features on a small portion of a country.

  • Atlas map this is a collection of maps in one volume
  • Sketch map maps which are roughly drawn.

A good sketch map should have the following characteristics:

  1. Neat and clear
  2. Title
  3. Frame
  4. Key
  5. Compass direction

Importance of maps in day to day lives

  1. Sketch maps are used to summarise information for easy reference.
  2. Used for locating other countries.
  3. Used for comparing sizes of countries.
  4. For locating climatic regions of different parts of the world.
  5. Give information on distribution of geographical phenomena e.g. vegetation on the earth’s surface.
  6. Help travellers to find their way.
  7. Used to calculate distance of a certain place.
  8. Used to locate physical features like landforms.

THE EARTH AND THE SOLAR SYSTEM

Solar system is the group of heavenly bodies comprising the sun and the planets.

The origin of the solar system

  1. The passing star theory

A star with a greater gravitational pull passed near the sun

It attracted large quantities of gaseous materials from the sun

The materials split, cooled and condensed to form planets

The planets were set in orbit by the passing star

  • The nebula cloud theory

There was a slowly rotating cloud of dust and gas called Nebula

It cooled and began to contact

Rotation speed increased and successive rings of gaseous materials were formed.

The rings condensed to form planets

The central gaseous material remained as the sun

Size of the earth

Equatorial diameter-12756km

Equatorial circumference-40085km

Polar diameter-39995km

Surface area of the earth-510×106 km2

Water surface – 73%.

The shape of the earth

The shape of the earth is called geoid/ovoid/oblate spheroid due to being an imperfect sphere by being wide at the equator and flat at the poles.

The position of the earth in the solar system

The 3rd planet from the sun

The earth and the heavenly bodies make the universe

The only planet that supports life

The home of man

Approximately 149m km from the sun

Rotation of the earth

Movement of the earth on its own axis (imaginary line through the centre from N pole to S pole

Rotates through 360º

Takes 24 hours (day) to complete 1 rotation

Rotates in an anticlockwise direction (west to east)

Effects of Rotation of the Earth

  1. Creates day and night because at any one time one side of the earth faces the sun (day) and the other remains in darkness (night).
  2. Causes deflection of winds and ocean currents in the N hemisphere to the left and in the S hemisphere to the right.
  3. It causes rising and falling of ocean tides.
  4. Causes time difference between longitudes

Effects of Rotation of the Earth on human activities

Revolution of the earth

  • Movement of the earth in its orbit around the sun.
  • It’s in anticlockwise direction.
  • The orbit of the earth’s revolution is elliptical.
  • Takes 365 ¼ days in a year or 366 days in a leap year (every 4 years).
  • The sun moves from the tropic of cancer to the equator and then towards tropic of Capricorn and back to the tropic of cancer.
  • 21st march and 23rd September are called equinoxes becausethe length of day and night is equal. The sun is vertically overhead at noon at the equator.
  • 21st June is called summer solstice because its summer in the N hemisphere. The sun is vertically overhead at noon at the tropic of cancer.
  • 22nd December is called winter solstice because its winter in the S. hemisphere. The sun is vertically overhead at noon at noon at the tropic of Capricorn.
  • Solstice is the period of maximum tilting of the earth towards the sun.

Effects of the Revolution of the earth

  1. Causes the four seasons summer, autumn, winter and spring due to the movement of overhead sun causing changes in the heat belt.
  2. Causes variation of day and night’s lengths due to the earth’s axis being inclined to the path of revolution at an angle of 60◦.
  3. Equinoxes have equal lengths of day and night.
  4. Summers have longer days and shorter nights.
  5. Winters have longer nights and shorter days.
  • Causes changes in the altitude of the midday sun due to the earth’s orbit being elliptical.
  • Highest altitude during equinox
  • Lowest altitude during solstices
  • Causes lunar eclipse due to revolution bringing the earth in line with the sun and the moon.

Locating places and features on a map using latitudes and longitudes

  • When giving the position of a place or features we with start with the latitude and then longitude

Major latitudes and longitudes

  • Major longitude is called prime meridian also called Greenwich meridian
  • In Africa it passes through:
  • Ghana(Accra)
  • Algeria
  • Burkina faso
  • Mali
  • All other longitudes are measured and named from prime meridian up to 180  ̊ on both sides
  • Major latitude are 3 passing through Africa
  • Equator 0  ̊  – divides Africa into two parts

                         It passes through;

  1. Gabon
  2. Congo
  3. DR congo
  4. Uganda
  5. Kenya
  6. Somalia
  • Tropic of cancer 231/2  ̊ north of equator

                           It passes through;

  1. Western sahara
  2. Mali

Calculating the time of different places in the world using longitudes

  • Rotation of the earth- This is movement of earth on its own axis
  • Distance between longitudes is measured in degrees
  • There are 360 meridians or longitudes
  • One complete rotation is 360 ̊
  • The direction of the rotation is from west to east i.e. anticlockwise direction.
  • One complete rotation takes 24 hours
  • All places found in the east of the Greenwich meridian will see sunrise first and therefore they are one hour ahead of those to the west

Effects of rotation of the earth

  1. Differences in time along different longitudes
  2. Occurrence of day and night

24hrs = 360 ̊

1hr = ?

360×1 ÷24 =15

Therefore 1hr =15 ̊   or 360  ̊= (24×60)minutes=1440min

̊= 1440÷360 ×1=4min

I Hr the earth covers 15º and 1º it covers 4 minutes

Calculating time of places found to the east of Greenwich Meridian

Example 1

The time in Accra 0 ̊ is 7.00am.calculate time in bermbera 45  ̊E

1hr =15  ̊

?    = 45  ̊ = 45÷15×1 =3hrs

So 3hrs is equivalent to 45  ̊ then add 3hrs   to 7.00am to get 10.00am

Example 2

Suppose the time at GWM is 12 noon what is the local time at Watamu 40◦E?

Time gained=40×4=160min=2 hours 40min

Local time at Watamu is 12.00+2.40=14.40-1200=2.40pm.

Example 3

At Dar-es-Salaam 40◦E time is 12pm what is the time at Ecuador 40◦E?

40◦+20◦=60◦

60×4=240min=4hours

Ecuador is behind in time =12.00-4=8 am.

NB

  • When calculating time to the east of Greenwich meridian, we add the time difference to the local time.

Calculating time of places found to the west of Greenwich Meridian

  • When calculating time to the west of Greenwich meridian we subtract the time difference to the local time

Example 1

A plane leaves off in New York, 74ºW at 7 am local time. What is the local time in Stockholm 18ºE

NB

  • If the places are on the same side subtract the degrees to get the difference and add or subtract from the reference time depending on which side the place is.

Types of maps

  1. Topographical maps ­

This shows selected natural physical features on a small portion of a country.

  • Atlas map this is a collection of maps in one volume
  • Sketch map maps which are roughly drawn.

A good sketch map should have the following characteristics:

  1. Neat and clear
  2. Title
  3. Frame
  4. Key
  5. Compass direction

Importance of maps in day to day lives

  1. Sketch maps are used to summarise information for easy reference.
  2. Used for locating other countries.
  3. Used for comparing sizes of countries.
  4. For locating climatic regions of different parts of the world.
  5. Give information on distribution of geographical phenomena e.g. vegetation on the earth’s surface.
  6. Help travellers to find their way.
  7. Used to calculate distance of a certain place.
  8. Used to locate physical features like landforms.

THE EARTH AND THE SOLAR SYSTEM

Solar system is the group of heavenly bodies comprising the sun and the planets.

The origin of the solar system

  1. The passing star theory

A star with a greater gravitational pull passed near the sun

It attracted large quantities of gaseous materials from the sun

The materials split, cooled and condensed to form planets

The planets were set in orbit by the passing star

  • The nebula cloud theory

There was a slowly rotating cloud of dust and gas called Nebula

It cooled and began to contact

Rotation speed increased and successive rings of gaseous materials were formed.

The rings condensed to form planets

The central gaseous material remained as the sun

Size of the earth

Equatorial diameter-12756km

Equatorial circumference-40085km

Polar diameter-39995km

Surface area of the earth-510×106 km2

Water surface – 73%.

Rotation of the earth

Movement of the earth on its own axis (imaginary line through the centre from N pole to S pole

Rotates through 360º

Takes 24 hours (day) to complete 1 rotation

Rotates in an anticlockwise direction (west to east)

Effects of Rotation of the Earth

  1. Creates day and night because at any one time one side of the earth faces the sun (day) and the other remains in darkness (night).
  2. Causes deflection of winds and ocean currents in the N hemisphere to the left and in the S hemisphere to the right.
  3. It causes rising and falling of ocean tides.
  4. Causes time difference between longitudes

Revolution of the earth

  • Movement of the earth in its orbit around the sun.
  • It’s in anticlockwise direction.
  • The orbit of the earth’s revolution is elliptical.
  • Takes 365 ¼ days in a year or 366 days in a leap year (every 4 years).
  • The sun moves from the tropic of cancer to the equator and then towards tropic of Capricorn and back to the tropic of cancer.
  • 21st march and 23rd September are called equinoxes becausethe length of day and night is equal. The sun is vertically overhead at noon at the equator.
  • 21st June is called summer solstice because its summer in the N hemisphere. The sun is vertically overhead at noon at the tropic of cancer.
  • 22nd December is called winter solstice because its winter in the S. hemisphere. The sun is vertically overhead at noon at noon at the tropic of Capricorn.
  • Solstice is the period of maximum tilting of the earth towards the sun.

Effects of the Revolution of the earth

  1. Causes the four seasons summer, autumn, winter and spring due to the movement of overhead sun causing changes in the heat belt.
  2. Causes variation of day and night’s lengths due to the earth’s axis being inclined to the path of revolution at an angle of 60◦.
  3. Equinoxes have equal lengths of day and night.
  4. Summers have longer days and shorter nights.
  5. Winters have longer nights and shorter days.
  • Causes changes in the altitude of the midday sun due to the earth’s orbit being elliptical.
  • Highest altitude during equinox
  • Lowest altitude during solstices
  • Causes lunar eclipse due to revolution bringing the earth in line with the sun and the moon.

PEOPLE AND POLPULATION

HUMAN ORIGIN

TRADITIONAL STORIES ON HUMAN ORIGIN

This is an attempt by communities of people to explain  their origin.

 It is given through Oral Traditions,  myths and legends.

 It mainly states that the first people were created by God

  1. Kikuyu community

According  to the Agikuyu,  God (Ngai) appeared and created their ancestors (Gikuyu  and Mumbi) at Mukurwe Wa Gathanga near present day Muranga

Gikuyu and Mumbi gave birth to 9 daughters who later formed the nine class

  • Bukusu

The bukusu of wetern Kenya belives that the fist man was called Mwambu.

He was made from mud by WELE KHAKABA (God the creator) at a place called Mumbo which means west.

God created a wife for him. Mwambu and his wife moved from Mumbo to the foothills of Mt. Masaba-mt elgon- where their descendants grew in numbers to become the Abaluhya community

  •  Maasai

Once upon a time Enkai (God) owned all the cattle in the world. One day he opened the sky and replaced all the cattle he owned from heaven to earth using a long rope.

Enkai created 3 communities on earth

The Torrobo(also the Ogiek) , the gikuyu whom God bless with seed and grain and the Maasai whom God blessed with all the cattle of the world

  • Akamba community

The akamba community believes that God was called Mulungu. He created the first man MUNDU and woman KIVETI.

They were then placed on top of Nzaui Hill in makueni.

He blessed them with children and livestock

  • Nandi community

According to the Nandi, the first two people came from the knees of a giant man, which began to swell until they burst. A man came from one knee and a woman from the other. These became the ancestors of the Nandi-speaking people of Kenya. This is an example of myths in certain communities that do not directly refer to God‟s creation.

RELIGIOUS STORIES ON HUMAN ORIGIN

This presents man and everything else as having  been created by  God.

 It is contained mainly in

  1.  The Bible (used by Christians)

God created the heaven and earth according to Genesis chapter 2

  • The Quran (used by Muslims).

Islam believes that all living and non living things were created by Allah

  • Hindu

The universe was created by Brahma. He is regarded as the hindu god of creation

Factors proving that Africa is the cradle of humankind

  • African Savannas were ideal for primates.
  •  The moist, warm and varied climate supported animal and plant life.
  • Archaeological sites were discovered in the Great Lakes region of eastern Africa and along the Great Rift Valley. This confirms that hominids were living  in this region by the time the rift valley  was being formed.
  • The earliest apes and various animals may have first lived around what is now Lake Victoria and the rift valley, then some went northwards into Europe and Asia. This was because, at that time, areas along the Equator (especially central and west Africa) were covered in thick forest. Around the Great lakes of East Africa was the Savannah (grassland with scattered trees and bushes). It was in this environment that man had his first home.
  • Due to earth quakes and volcanic  eruptions during  the formation  of the great rift valley, allot of dust was brought up, which covered places where hominids  had left their weapons, tools, their own bones, and those of other animals.  These became archaeological sites in east Africa
  •  Remains found in Africa especially Eastern Africa are evidence that Africa is the cradle of mankind.
  •    
  •    

Evolution is a natural process of gradual and continuous  change of living  organisms  from a lower (simpler)  state to a better-adapted (complex) and superior one.

Archaeological site or prehistoric site

Is a place where human remains were found

Archaeologists

Are scientists who excavated the human remains for study

Fossils

STAGES OF MAN’S EVOLUTION

  1. Ramapithecus also called kenyapithecus

The 15-12 million year-old remains of Ramapithecus  were found by Mary and Louis Leakey at Fort Ternan near kericho and also at Samburu hills  and in the Lakes Turkana and Baringo  basins. Ramapithecus  and other manlike  creatures were also discovered in Europe, India and China.

  • Had much larger teeth, skull and jaws.
  • His brain was smaller  than modern man‟s, but larger than that of the most intelligent  ape: the Gorilla.
  • Homo habilis (Practical man).

This was the first species of the genus Homo. His two and a half to one and a half million- year old remains  were found at Olduvai Gorge by Jonathan Leakey in 1964, Hadar and Omo River valley  in Ethiopia  and Koobi-For a in the lake Turkana area in 1972.

Characteristics of Homohabilis

  • He was five feet tall.
  • He had a skull similar  to modern man‟s in shape.
  • He was omnivorous.
  • He could grasp objects.

  • He was bipedal (walked on two legs).
  • He made and used tools, such as hand-axes, crude spears and arrowheads from stone,
  • bone and wood.
  • Homo sapiens (Thinking/Intelligent  man). 

Homo sapien appeared between two hundred thousand and a hundred and fifty  thousand years ago. 

Characteristics of Homosapien

  • He was under six feet tall
  • He had small teeth.
  • He had a steep and well-rounded  forehead.
