UFAHAMU:

Soma taarifa ifuatayo kisha ujibu maswali:

Mwangeka Mwachoni alizaliwa mwaka wa 1930 katika tarafa ya Mwanda, Wilaya ya Taita-Taveta.

Angalikuwa hai leo bila shaka angalikuwa mmoja wa watu mashuhuri wenye kuheshimiwa kwa ujasiri wao.

Mwangeka alipata taabu mno utotoni wake kwa sababu ya malezi ya shida ya wazazi wake ambao

walishindwa hata kumpeleka shule. Juu ya hivyo aliweza kuinuka na kuwa kijana mahiri sana tena

mkakamavu na mchanga-mfu. Alikuwa akiwatii wazazi wake na kuwaenzi. Alijitwika jukumu la kuiangalia

ile milki yao ndogo waliyokuwa nayo na kuwatumikia bila kinyongo. Ustadi aliokuwa nao Mwangeka

umeweka kumbukumbu ya vitendo vya ushujaa wake wakati angali ni mdogo. Wakati huo, kila siku alikuwa

akichunga ng'ombe wa baba yake milimani kulikokuwa na hatari za kila namna za wanyama wa mwitu. Siku

moja alipowapeleka ng'ombe wao malishoni aliwaona simba wawili katika mlima Vuma waliotaka

kuwashambulia wale ng'ombe. Mwangeka alipambana nao kwa uta na mshale na akaweza kuwaua. Hapo

ndipo sifa zake za ujasiri ziliposambaa Taita nzima.

Mwangeka alikuwa mtu mwenye hekima na busara nyingi na alikuwa mwenye maarifa ya mambo mengi

ya ajabu. Mojawapo ya mambo aliyoyajua ni vipi kajipinga na kujihami na shari za maadni wasiweze

kumwona au kumjua alipo na hali yeye amewakabili na kuwatazama. Basi alipofika umri wa miaka ishirini

18

na tano alianza kuwa mashuhuri na sifa zake zilizagaa kila mahali. Wakati huo alikuwa amekwisha oa.

Alimwoa mwanamke aitwaye Magema, bibi ambaye mwanzo wa kuolewa alionyesha hubo nyingi kwa

mumewe. Lakini baada ya miaka michache alianza kubadilika hulka na kuwa na umbeya na udadisi mwingi.

Kila mara alikuwa akimsaili mumewe kuhusu ushujaa wake na mengi mengine yasiyostahili kuulizwa, bali

mradi aelezwe tu. Alikuwa akistaajabu kumwona mumewe akiweza kuishi msituni kwa muda wa mwezi

mzima bila chakula, na vile alivyoweza kwenda kwa miguu kutoka Kasigau mpaka Mwanda, mwendo wa

kilomita mia mbili, bila kuchoka. Pia, ilikuwa ikistaajabisha vile alivyoweza kupotea asionekane na maadui

zake (ambao wakati huo walikuwa ni wazungu) akiwacha nyuma kivuli chake ambacho ndicho

kikiwashambulia na kuwaua maadui hao.

Siku moja bibi alimbembeleza sana mumewe amweleze maarifa na miujiza atumiayo, lakini Mwangeka

alikataa kabisa kumdokezea habari hiyo. Mwishowe kero lilizidi na Mwangeka hakuweza tena kumkatalia.

Aliona heri amweleze lakini alimkanya asiweze zabizabina na kumweleza mtu yeyote, kwani hiyo ilikuwa

siri yake. Akitoa siri hiyo kumwambia mtu, maisha yake yatakuwa hatarini, mahasimu zake wakikipiga kivuli

chake.

Mwangeka alifanya kazi kubwa katika kuupigania uhuru wa Kenya. Aliwafukuza wazungu na kuwaua

wengi. Huu ndio wakati ambapo Taita, na Kenya kwa jumla, ilipomtambua Mwangeka kuwa ni kiongozi asiye

na kicho, aliyejitolea maisha yake yote kwa ajili ya nchi yake. Yeye ndiye aliyekianzisha chama cha vijana

wa kitaita kilichopigania usawa wa wataita. Alitembelea sehemu nyingi za Kenya na akakutana na Jemadari

Dedan Kimathi, mmoja wa viongozi wa Mau Mau, wapiganaji wa vita vya uhuru. Viongozi hao wawili

walizungumza na kushauriana namna ya kupambana na taabu zilizo wakabili na wakaahidiana kwamba

watakuwa wakitembeleana mara kwa mara.

Huku nyuma nyumbani kwa Mwangeka mambo hayakuwa mema kama alivyofikiria. Baada ya yeye

kuondoka wazungu wawili walifika na kumbembeleza mkewe awaeleze jinsi Mwangeka alivyokuwa

akifanya. Kwanza mkewe alikataa kuwaeleza lakini baada ya kupewa gunia moja la mchele na shilingi kumi

pamoja na kuahidiwa mambo mema kadha siku za mbele, aliwaeleza siri zake zote!

Ilikuwa usiku, tarehe 23 Machi 1966, Mwangeka alipoonekana amelala juu ya jabali kubwa, maiti,

kiwiliwili chake kiasi cha maili tatu hivi kutoka kivuli chake.

MUHTASARI:

Mzee Kondoo: Wenyeji wa kijiji cha maendeleo; mabibi na mabwana pokeeni salamu zangu na shukrani

kwa kuhudhuria mkutano huu. mimi pamoja na wazee wenzangu tuliamua kwa kauli moja kuwaita nyote hapa

ili kujadili maendeleo ya kijiji chetu. Jambo linalotukera sisi wazee ni kwamba hali ya kijiji chetu inazidi

kuzoroteka. Kijiji chetu kiliitwa maendeleo sisi wazazi wake tulipokuwa na rai ya kuleta maendeleo. Wake

19

kwa waume tulijifunga vibwebwe na kwa kweli juhudi zetu zilitoa matunda mema. Sasa nguvu zimeanza

kutuishia; leo tupo, kesho tutakuwa hatupo. Ninyi ndio mtakaoshika usukani. Kama tunavyoona, mambo

yakiendelea namna hii, watoto wenu wataishi maisha ya dhiki. Tungependa ninyi wenyewe mtueleze kwa nini

kijiji maarufu cha maendeleo kinarudi nyuma badala ya kuendelea mbele. Kila anayetaka kutoa hoja zake

atapewa fursa ya kufanya hivyo. Lakini kwanza mzee mwenzangu ana machache ya kusema.

Rojo: Asante sana mzee Kondoo. Kwa upande wangu naona kwamba tumekuwa pweza kujipalia makaa

na kwa mintaarafu hii, maendeleo ya kijiji chetu yakaanza kuzoroteka. Kwa ufupi, tunazaa watoto tusioweza

kuwalea. Ni hivi majuzi tu tulipomkuta mtoto mmoja amezirai …

Jara: Wee! Kaa chini. Usituletee aibu hapa. Sisi ni watu wa kuheshimiwa. Ufahamu kwamba hukupewa

fursa ili uanze kuchambua nyumba za wengine. Mungu mwenyewe alitoa amri kwamba watu wazae mpaka

waijaze dunia.

Jilo: Mimi namwunga mkono Jara. Anayosema Rojo hayafai kuruhusiwa kuzungumzwa tena.

Mzee Kondoo: Hatukuwaita hapa mje mgombane. Rojo hajataja jina la mtu wala hajamaliza kutoa hoja zake.

Endelea bwana Rojo.

Rojo: Nashukuru Mzee Kondoo. Ndugu, mimi nitatoa ule ukweli. Humu kijijini mwetu mna watoto

ambao hawaendi shule. Kazi yao ni kuzurura kila mahali na kuokotaokota mali za watu. Hata huingia

mashambani mwa watu wakaiba matunda, mihogo, mahindi na mazao mengine wakapeleka mijini kuuza.

Mimi kitendo kama hiki nakilaani kwani ndicho kinachorudisha maendeleo ya kijiji chetu nyuma.

Uledi: Hayo usemayo ni kweli. Juzi walikuja usiku mwenyewe siko wakavunja mlango wakafagia

nyumba yangu fyu! Vitendo vya vijana hawa vinadhihirisha ukosefu wa malezi bora. Mabwana na mabibi,

mimi sipingi uzazi lakini yule azaaye atambue jukumu lake la kuwalea vizuri watoto hao hata kama ni ishirini:

awalishe, awavishe, awatibu wawapo wagonjwa, awafunze tabia njema na kupelekwa shuleni ili wakuapo

waweze kujimudu na kushirikiana nasi katika kuendeleza kijiji chetu.

Heri: Mabibi na mabwana mtaniwia radhi kwa vile ambavyo sina mke wala watoto. Hata hivyo sitasita

kutoa maoni yangu. Wasemayo wenzetu ni ya kuungwa mkono. Watoto wakosao malezi bora ndio hatari

katika kijiji chetu. Wakazi wa kijiji hiki wamekuwa waoga hata hawawezi kujenga maduka wakaendesha

biashara zao humu.

Rojo: Mbali na uhalifu wa vijana wetu sisi watu wazima pia twafaa kulaumiwa. Kwanza tumeshindwa

kutimiza wajibu wetu kwa ajili ya ulevi. Tumeshiriki ulevi hata kwamba hatudiriki makazini wala mwetu

majumbani. Vipi tutadumisha nidhamu katika jamii zetu? Pia tusisahau kwamba ili kuwa na jamii ya kuimudu

siku hizi hali ya maisha imepanda juu na tusipokuwa na busara yatatushinda.

Uledi: Zaidi ya hayo inatupasa tuzingatie miradi mbalimbali itakayotuletea maendeleo …

CHEMISTRY

Form three chemistry holiday assignment

1. Below is a passage describing how Sodium chloride is obtained from Lake Magadi in the Rift

Valley? Study it and answer questions that follow. Lake Magadi consists of massive deposits of

trona (Na2CO3.NaHCO3.2H2O) a crystalline solid. This solid material has formed as a result of the

high rate of evaporation on this water mass with high salt content. Below the trona is a mother liquor

of Sodium chloride and Sodium carbonate with a density of 1.26x103kgm-3. The less soluble salt

crystallises out first. This knowledge is made use of in separation of dissolved solids; a process

known as fractional crystallisation. Sodium chloride and sodium carbonate have the same solubility

at 36.10C but sodium chloride is more soluble below this temperature while sodium carbonate is

more soluble above this temperature. During the process of obtaining sodium chloride mother liquor

is made to flow into channels and then pumped into salt fields where initial evaporation by solar

energy occurs. These are the pre-concentration ponds where the liquor flows from one pond to

another by gravity. Precipitation of trona and sodium carbonate monohydrate occurs. Eventually the

concentration of common salt equals that of sodium carbonate and the two form 16% of the mother

23

liquor. The liquor is pumped into salt making ponds where further evaporation occurs. During hot

months of the year the daily temperatures of this liquor can be as high as 400C but generally below

36.10C. During night temperatures average 200C. Became of the difference in solubility of salt and

carbonate and the high variation of temperatures between day and night, the two deposits at different

times. Impure salt is obtained which is purified by washing with saturated sodium chloride solution.

The purified salt is then iodised to produce coarse salt. Some of the coarse salt will be treated by

adding red oxide (Iron (II) Oxide for cattle.

Coarse salt contains 99.5% NaCl, 0.03% NaF,

0.4% sodium carbonate and 0.0037% iodine.

b) What does the precipitation of trona and sodium carbonate monohydrate in the pre-concentration

ponds tell you about the relative concentration of sodium carbonate compared to sodium chloride

in the lake?

c) What is the mass of sodium chloride in 1000kg of mother liquor when concentration of salt

equals concentration of sodium carbonate?

15. In an experiment to determine g, the acceleration of free fall, it is necessary to make careful

measurements both of length and time. Values for these two quantities are then substituted in an

appropriate formula to enable of to be calculated:

(i) Draw a diagram of the arrangement of the apparatus you would use to determine g, indicate on

the diagram the exact length that must be measured for the calculations.

(ii) Describe fully how the time internal needed in the calculation is measured.

(iii) Write a relationship of the form g = 4𝜋2

𝑇2L which would enable the acceleration of free fall to be

calculated using the measurements of length and time you have described in your answers to (i)

and (ii). How could you improve the reliability of your determination of g?

16. The following table gives the scale readings of the pointer for different attached masses:
