ROCK AND THEIR FORMATION

What is rock?
Rock refer to the combination of different materials. Rock can be classified according to their formation (origin)

TYPES OF ROCK
1. Igneous rocks
2. Sedimentary rocks
3. Metamorphic rocks

1. IGNEOUS ROCKS
These are rocks which formed through the process of solidification and compacted of molten material called Magma either within or outside the earth crust.

*Why Igneous rocks refers to the mothers rock?
1. The other rock it's owe their origin
2. Formation of soil fertilite
3. It's not originated from another rock it made up itself

Characteristic of Igneous rocks 
1.They do not occur in layer
2. Most of them are crystalline
3. They do not contain fossils
4. The origin of another rock

2. SEDIMENTARY ROCK
These rock are formed after accumutation of deposited material of rock and compacted together.The process of formating this rock is called sedimentation
It occur after accumutation of sediment material and compacted together and cementation.

                        The rock cycle

Characteristic of sedimentary rock
1. They are non crystalline
2. Sometimes contain fossils 
3. Are found in layer
4. Originated from igneous rock
*Due to the mode of formation sedimentary rock are formed in three process like this below

1. Mechanically formed
Formed by accumutation of material deriven from other rock which have been cemented together eg.sandstone

2. Organically formed
Formed due to remains of plants and animals eg.chalks and coal

3. Chemically formed
Formed through chemical precipitation of solution eg.rocks, salts.

3. METAMORPHIC ROCK
These rock are formed when Igneous and Sedimentar rock are subjected to heat and pressure then rock change their appearance and chemical properties

IMPORTANT OF ROCK FOR HUMAN 
1. Construction activities

UPIMAJI WA KIELIMU NA AINA ZAKE

UPIMAJI WA KIELIMU

Dhana ya Upimaji wa kielimu

Ni mchakato unaotumika katika kupata data na mabadiliko ambayo mwezeshaji huweza kujua uwezo na ujuzi wa mwanafunzi na mabadiliko ya kitabia.

Malengo ya Upimaji wa kielimu

(a) kuangalia kiwango ambacho malengo ya mada yamefikiwa na mwanafunzi

(b)kuamsha ari ya mwanafunzi kujifunza zaidi

(c)kumpa mwezeshaji dira ya kumwongoza katika kuboresha ufundishaji

(d)kusaidia katika uwekaji wa kumbukumbu za kila mwanafunzi

(e) kupata taarifa za mabadiliko katika stadi, ujuzi na mwenendo wa mwanafunzi

Umuhimu wa Upimaji

Katika elimu Upimaji wa maendeleo ya mwanafunzi hufanywa ili kujua maendeleo ya mwanafunzi na hasa kujua ni kiasi gani mwanafunzi amepata stadi na maarifa yatakayomwezesha kuishi maisha bora na kuwa na manufaa katika jamii anamoishi.

Umuhimu wa Upimaji wa maendeleo ya mwanafunzi

1.kumwezesha mwezeshaji kutoa uamuzi wa mafundisho ya kila siku.

2.kujua iwapo mitaala na ufundishaji unastahiri unakidhi mahitaji ya mwanafunzi ili kusaidia katika

Kuwapanga wanafunzi ili waweze kufundishwa kulingana na uwezo wao

Kujua kama wanafunzi wako tayari kwa mafunzo mapya

• Kuonyesha maendeleo ya mwanafunzi kwa ujumla
• Kuamsha ari ya wanafunzi katika kujifunza
• Kutambua sehemu maalumu zinazohitaji kurudiwa
• Kugundua matatizo au ugumu wanaoupata wanafunzi katika kujifunza
• Kugundua wanafunzi ambao wako nyuma
• Kuonyesha ubora au ubovu wa ufundishaji
• Kujua kiasi ambacho mwanafunzi amemudu katika kupata stadi za lazima

3.Kumsaidia kuboresha ufundishaji

4.Kuonyesha uwajibikaji wa mwalimu na mwanafunzi

5.Kusaidia uchaguzi wa mwanafunzi na utoaji wa vyeti.

AINA ZA UPIMAJI WA MAENDELEO YA MWANAFUNZI

Zipo aina nne za Upimaji wa maendeleo ya mwanafunzi.Aina hizo ni:

• Upimaji awali
• Upimaji endelevu
• Upimaji wa mwisho au tamati
• Upimaji tatuzi

UPIMAJI AWALI

Upimaji wa aina hii humsaidia mwalimu kuelewa mahali ambapo mwanafunzi anapaswa kuanzia katika kujifunza.hivyo unapaswa kuzingatia nyanja zote za kielimu kama utambuzi, mwenendo na vitendo anavyomudu mwanafunzi anapoandikishwa shule.hapa unaweza andaa maswali ya kuwauliza mfano utaweka picha na kuwatawala waeleze wanachokiona katika picha na kumtaka mmoja mmoja ajibu.

Fomu ya Upimaji awali

UPIMAJI ENDELEVU

Upimaji wa aina hii hutolewa wakati mwalimu anaendelea kufundisha.mfano mwalimu anapofundisha mada fulani basi anaweza kutoa zoezi au jaribio kila baada ya kufundisha kipengele kimoja.upimaji huu unalenga kuona kama mwanafunzi amemudu kipengele hicho kabla ya kipengele kinachofuata kufundishwa.Hivyo katika upimaji huu mwalimu anaweza kutumia zana zifuatazo:

1.Orodha hakiki ya kupima taaluma

Ni zana mojawapo ya Upimaji inayotumika kupima mabadiliko na mwelekeo wa mwanafunzi kimwelekeo,kiustadi na kiujuzi .

2.Mazoezi

Ni zana nyingine ambayo mwalimu anaweza kutumia kupima maendeleo ya mwanafunzi.mazoezi yanaweza kutolewa kama maswali na maelekezo ya utekelezaji ili kupima kiwango cha uelewa wa mwanafunzi kuhusiana na somo lililofundishwa.vilevile mazoezi yanaweza kutumika kama njia ya kukazia maarifa mapya yaliyofundishwa kwa kila mada.

3.Majaribio

Majaribio hupima kiwango cha ufahamu,uelewa na mabadiliko ya mwenendo na ujuzi/vitendo vya mwanafunzi katika mambo mbalimbali.jaribio linaweza kutolewa kabla ya kufundisha au baada ya kufundisha.Zana hii humwezesha mwanafunzi kuelewa uwezo wake na kumpa ari ya kujibidiisha zaidi katika kujifunza.

UPIMAJI TAMATI

 huu unatumika kujua kama wanafunzi amepata maarifa, stadi na mielekeo katika nyanja zote za kielimu kama ilivyoorodheshwa katika mhtasari wa somo husika.Upimaji wa aina hii hutolewa mwisho wa kipindi cha mafunzo au baada ya mwanafunzi kumaliza ngazi fulani ya elimu.Upimaji huu una lengo la kupima kiwango cha mafanikio kwa ajili ya kuendelea na mafunzo ya juu pamoja na kutunuku mwanafunzi cheti.

UPIMAJI TATUZI

Wanafunzi hutofautiana katika kujifunza.Kuna wanafunzi ambao huelewa haraka na wengine ambao ni wazito kujifunza.Tofauti hizo zinapojitokeza mwalimu ajaribu kufanya Upimaji tatuzi ili kuona mwanafunzi ana matatizo gani katika kujifunza kisha ayatatue.Endapo mwalimu ataona kuwa mwanafunzi anaendelea kuwa mzito katika somo itabidi afanye uchunguzi wa kina ili atatue tatizo Hilo.Lengo la Upimaji wa aina hii ni kutafuta kwa undani sababu zinazomfanya mwanafunzi awe mzito wa kujifunza ili ziwekewe mkakati wa kuziondoa.

NYANJA ZA UPIMAJI WA KIELIMU NA NGAZI ZAKE

Nyanja ni maeneo makuu ya ujuzi,matendo na mwelekeo ambao mwanafunzi anatarajiwa kuwa nayo baada ya mafunzo.Nyanja hizo ni utambuzi, vitendo na mwelekeo/mwenendo

NYANJA ZA UTAMBUZI (COGNITIVE)

Hapa tutajikita zaidi katika kipengele cha utambuzi.

Kipengele cha utambuzi huhusisha:

• Maarifa
• Ufahamu
• Matumizi
• Uchambuzi
• Uundaji
• Tathmini

1.Maarifa

Kinacholengwa katika kipengele hiki ni kujenga taswira ya dhana, tukio au tendo liote mzizi kwenye sehemu inayohifadhi mambo ndani ya ubongo wa mwanandamu. Mwanafunzi anatakiwa aweze kukumbuka kile alichofundishwa na kutaja kwa kauli au maandishi.

2.Ufahamu

Katika kipengele hiki mwanafunzi anatakiwa aweze:

Kutafsiri

Kufupisha

Kubashiri

Kuandika kwa muhtasari

Mifano ya vitenzi vya upimaji ni: fupisha, bashiri, andika muhtasari.

Mfano :- andika namba inayofuata katika mfululizo huu: 2,4,6,8……

3.Matumizi

Hapa kinachosisitizwa ni matumizi ya maarifa hali halisi. Mwenendo unaojengwa hapa ni ule uwezo wa mwanafunzi kutumia ujumbe, kanuni na fikra za maarifa ya ufahamu alionao katika mazingira halisi. Mfano wa vitenzi vya upimaji ni:- tumia, badili sentensi zifuatazo kuwa katika hali fulani, chambua nomino, kitenzi, onesha, kazia, n.k.

4.Uchambuzi

Kipengele hiki kinahusu;

• Uchambuzi wa dhana
• Tukio
• Maarifa fulani

Katika uchambuzi, ufundishaji hulenga kumwezesha mwanafunzi kuchunguza na kutaja uhusiano wa mambo. Mifano ya vitenzi vya upimaji ni:- chambua, husianisha, fafanua, tofautisha, pangua, tenganisha, pambanua, n.k

Advertisement

Mfano: Chambua sentensi ifuatayo: Mtoto anasoma kitabu

5.Uundaji

Katika kipengele hiki, upimaji hulenga uwezo wa mwanafunzi katika kugundua, kuvumbua au kuunda jambo. Mfano: kuandika sentensi kwa namna ya kipekee, kugundua kanuni, kutoa jumuisho, n.k.

Mifano ya vitenzi vya upimaji ni:- Unda, unganisha, panga, weka pamoja, jumuisha, panga maneno yafuatayo ili yalete maana au sentensi kamili. Anapika kitamu mama chakula jikoni.

6.Tathmini

Kipengele hiki ni kama mwamvuli wa vipengele vingine vyote. Kinachoongezeka hapa ni vigezo vinavyowekwa katika upimaji wa uhalaliau ubatili wa jambo; mfano Uzuri wa jambo, n.k. mifano ya vitenzi vya upimaji ni:- tathmini, toa uamuzi, chagua, toa maoni yako, n.k. mfano: Ipi kati ya njia zifuatazo ni sahihi kuhifadhi mazingira? “kupanda miti au kulima kando kando ya vyanzo vya maji”

Mbinu na Zana za Tathmini

Tathmini ya elimu inaweza kutekelezwa kwa kutumia mbinu na zana tofauti kulingana na mahitaji ya wanafunzi ambayo ni:-

1.Kuchunguza kwa makini

2.Mitihani

3.Maswali ya dodoso

4.Mahojiano ya ana kwa ana, n.k.

          NB: Mitihani hutumika zaidi katika tathmini ya elimu

UTAMADUNI WA MTANZANIA

UTAMADUNI

Maana ya Utamaduni

Ni mfumo mzima wa maisha ya watu fulani,jamii au nchi,mila na desturi zao za asili,jadi au Imani.Utamaduni hutambulisha na kuwaunganisha watu wa jamii husika kwa njia ya lugha, chakula,mavazi, nyimbo, michezo, Mila na desturi.

UTAMADUNI WA MTANZANIA

Ni mfumo wa maisha ya watanzani jinsi wanavyoishi kwa kufuata mila, desturi,jadi, Imani michezo na maendeleo yao kijamii,kiuchumi na kisiasa.Tanzania inamakabila yasiyopungua 120 yote yana mila na desturi zao za namna tofauti.Aidha utamaduni wa MTANZANIA umeunganishwa na lugha moja ya kiswahili ambayo ni lugha ya Taifa na ni lugha ya mawasiliano katika nchi za Afrika ya Mashariki.

VIELELEZO VYA UTAMADUNI WA MTANZANIA

Utamaduni wa Mtanzania unajitokeza katika mambo mbalimbali kama vile lugha,mila, desturi, michezo, Sanaa na mavazi.

LUGHA:Ni chombo cha mawasiliano ambacho hutumika kama utambulisho wa jamii katika kuelimisha,kupashana habari na kubadilishana mawazi

MILA:Ni jumla ya mambo yanayofanywa na jamii husika kulingana na asili, mazingira na mienendo ya jamii hiyo.mfano wa mila ni jando na unyago

DESTURI:Ni mambo ya kawaida yanayofanywa mara kwa mara na wanajamii;Pia huweza kubadilika kulingana na mahali na wakati.mfano jamii zingine hutambuliwa kulingana na mavazi,vinywaji na vyakula

MICHEZO:Ni mambo yafanywayo kwa ajili ya kujifurahisha,kujichangamsha au kupitisha wakati.kwa Tanzania kuna aina mbili za michezo ambayo ni michezo ya jadi na michezo ya kisasa.michezo ya jadi ni kama vile kurusha mkuki,kucheza BAO,kukimbia,kubembea na kuruka Jamba.michezo ya kisasa ni kama vile mchezo wa ngumi, mchezo wa kuogelea na michezo mingine.

SANAA:Ni ufundi anaoutumia mtu ili kuwakilisha fikra au mawazo yake katika namna inayoburudisha na kufikirisha.tunaweza kuiona kazi ya sanaa kupitia fasihi,uchoraji,ususi,ushonaji,uchongaji na ufinyanzi

Sanaa hizi zimegawanyika katika makundi matatu ambayo ni

(a) Sanaa za maonyesho mara nyingi huoneshwa kwa umbo maalumu za zinaweza kuhifadhiwa kwa matumizi ya baadaye.mfano ufinyanzi.

(b)Sanaa ghibu ni zile sanaa zisizoonekana katika umbo maalumu au kushikika bali hugusa hisia mfano ushairi,uimbaji na muziki.

(c)Sanaa za vitendo huonekana katika uzuri wa umbo na hufanyika kwa vitendo mfano uigizaji,vichekesho,majigambo na nyimbo

NJIA ZA KUBAINI PANDE KUU NNE ZA DUNIA
Pande kuu za Dunia zinaweza kubainishwa kwa kutumia njia mbalimbali kama vile
(i) Kubaini pande kuu za Dunia kwa Kutumia mawio na machweo ya jua
(ii) Kubaini pande kuu za Dunia kwa Kutumia uelekeo wa kivuli
(iii) Kubaini pande kuu za Dunia kwa Kutumia uelekeo wa nyota
(iv) Kubaini pande kuu za Dunia kwa Kutumia ramani.
(v) Kubaini pande kuu za Dunia kwa Kutumia dira


(i) Kubaini pande kuu za Dunia kwa Kutumia mawio
Kuangalia jua linapochomoza wakati wa asubuhi na jioni unaweza kubaini pande kuu za Dunia. Hivyo wakati wa asubuhi ukisimama kuliangalia jua linapochomoza upande huo ni Mashariki na upande wako wa kulia huwa kusini na upande wako wa kushoto huwa kaskazini na Magharibi huwa nyuma ya mgongo wako. Vilevile ukisimama kuliangalia jua linapozama jioni upande huo ni Magharibi na upande wako wa kulia huwa kaskazini na upande wako wa kushoto huwa kusini.

(ii) Kubaini pande kuu za Dunia kwa Kutumia uelekeo wa kivuli
Uelekeo wa kivuli chako wakati wa asubuhi na jioni unaweza kubaini pande kuu za dunia.Kwa kawaida unapotembea wakati wa asubuhi upande ambao kivuli chako kilipo ndio Magharibi na unapotembea wakati wa jioni upande ambao kivuli chako kilipo ndio Mashariki.
NB: Vigumu kufanya utambuzi wa pande kuu za Dunia wakati wa mchana kwa kuangalia uelekeo wa kivuli chako.

Picha ya kubaini pande kuu za dunia kwa Kutumia uelekeo wa kivuli

(iv) Kubaini pande kuu za Dunia kwa Kutumia ramani

Ramani ni mwongozo mmojawapo unaotumika kubaini pande kuu za Dunia. Miongoni mwa vipengele muhimu vya ramani ni alama ya uelekeo wa kaskazini na hutumika kurahisisha kubaini pande kuu za Dunia yaani Kaskazini, Kusini ,Mashariki na Magharibi.

Mchoro wa ramani kuonesha uelekeo wa kaskazini 

(v) Kubaini pande kuu za Dunia kwa Kutumia dira

Dira ni kifaa kinachotumiwa kutambua uelekeo wa kaskazini.Zipo aina mbili za dira ambazo ni

(i)Dira ya kidijitalia hutumia teknolojia kuonesha uelekeo na imeunganishwa kwenye GPS saa za kisasa simu janja na vyombo vya usafiri kama magari boti na ndege

(ii)Dira ya analojia ambayo hutumia vipande vya sumaku au sindano yenye sumaku kuelekeza upande wa kaskazini.

KIPIMIO CHA RAMANI

Ni uwiano kati ya umbali halisi na umbali ulioko kwenye ramani.

Zipo aina tatu za ramani ambazo ni
1.Kipimio kikubwa cha ramani
Hiki ni kipimio ambacho hutumika kuwakilisha maeneo madogo kama vile majengo, viwanja vya michezo na mashamba. Kipimio hiki huoneshwa kwa tarakimu kati ya 1:5,000 au 1:10,000 na 1:25,00

2.Kipimio cha kati cha ramani
Hiki ni kipimio ambacho hutumika kuwakilisha maeneo ya miji, mkoa na wilaya. Kipimio hiki huoneshwa kwa tarakimu za kati ya 1:50,000 na 1:250,000.

3.Kipimio kidogo cha ramani 
Hiki ni kipimio ambacho hutumika kuwakilisha maeneo makubwa sana kama vile nchi, mabara na dunia. Kipimio hiki huoneshwa kwa tarakimu zenye thamani kubwa kati ya 1:5000,000 na 1:1,000,000

Uwasilishaji wa ramani 
Kipimio cha ramani kinaweza kuwasilishwa kwa njia tatu ambazo ni
1.Njia ya sentensi 
Mfano:Namna ya kuonesha kipimio hicho kwa njia ya sentensi itakuwa:"sentimeta moja kwa kilometa moja"
2.Njia ya uwiano au sehemu 
Njia hii ya kuonesha kipimio cha ramani Kwa uwiano au sehemu vikiwa katika thamani au vipimo vya aina moja kwa mfano 1:50,000 au humaanisha sentimeta moja kwenye ramani inawakilisha sentimeta elfu hamsini kwenye ardhi.Ikiwa sentimeta moja kwenye ramani inawakilisha kilometa moja kwenye ardhi ni lazima kilometa hiyo moja ibadilishwe kwenye sentimeta
                            Km1=M1000
                              M1=Sm100
            Kwa hiyo Km1=Sm100×1:100,00
Kwa njia ya uwiano hii itaoneshwa hivi 1:100,000
Kwa njia ya sentensi itaoneshwa hivi ¹/100,000
3.Njia ya mstari
Njia hii mstari huchorwa na kugawanywa katika sehemu mbili.sehemu ya kwanza kipimio kimegawanywa katika sehemu ndogondogo na sehemu ya pili inaonesha vipimio kamili

MAP SCALE

A map scale is a crucial element of a map that shows the relationship between distances on the map and the actual distances on the ground. It allows the user to understand how much real-world distance is represented by a specific distance on the map. There are three main types of map scales:

1. **Ratio Scale (or Representative Fraction)**: This scale expresses the ratio between map distance and ground distance as a fraction or ratio, such as 1:50,000. This means that one unit of measurement on the map (e.g., 1 inch or 1 centimeter) represents 50,000 of the same units on the ground. For example, 1 cm on the map equals 50,000 cm (or 500 meters) in reality.

2. **Bar Scale (or Graphic Scale)**: This scale is a visual representation, usually a bar or line marked with units of distance. It allows the user to measure distances directly using the scale bar. It remains accurate even if the map is enlarged or reduced.

3. **Verbal Scale (or Statement Scale)**: This scale uses words to describe the ratio of map distance to ground distance, such as "1 inch equals 1 mile" or "1 centimeter equals 10 kilometers." It provides an easy-to-understand description of the scale.

The concept of scale is essential in various contexts for several important reasons:

1. **Accuracy in Representation**: Scale allows for the accurate representation of large areas or objects on a smaller medium, such as a map or blueprint. This enables us to visualize and analyze geographical regions, architectural designs, or any other spatial information effectively.

2. **Understanding Proportions**: Scale helps us understand the relative size and proportion of different elements within a representation. For example, in a scaled drawing, we can accurately compare the sizes of rooms, buildings, or landscapes.

3. **Navigation and Travel**: In maps, scale is crucial for determining distances between locations. It helps travelers and navigators estimate travel times and plan routes efficiently.

4. **Data Visualization**: Scale is important in creating graphs, charts, and diagrams. It ensures that data is presented accurately and proportionally, making it easier to interpret and analyze trends, patterns, and relationships.

5. **Scientific Research**: Scale is vital in various scientific fields, such as biology, astronomy, and geology. It allows researchers to study phenomena at different levels, from the microscopic to the cosmic, and understand their implications in a broader context.
