Cov hlau nplaum sib nqus yog cov cuab yeej siv taug kev qub siv los txiav txim plaub qhov tseem ceeb: sab qaum teb, sab qab teb, sab hnub tuaj, thiab sab hnub poob. Qhov ntsuas hluav taws xob tau tsim los ntawm rab koob sib nqus uas hloov kho rau lub ntiaj teb cov chaw sib nqus kom nws ib txwm taw tes rau sab qaum teb-qab teb. Yog tias koj poob yam tsis muaj lub koob, koj tuaj yeem ua koj tus kheej siv ib daim hlau uas muaj hlau nplaum thiab ib lub tais dej.

Ntu 1 ntawm 3: Sau Cov Khoom Siv
Kauj Ruam 1. Txiav txim siab lub hom phiaj uas yuav tsum tau ua rau hauv daim duab
Koob txhaj tuaj yeem siv tau txhua yam hlau uas tuaj yeem siv ua hlau nplaum. Xaws koob tau siv ntau zaus, tshwj xeeb tshaj yog vim tias lawv feem ntau muaj nyob hauv cov khoom siv thawj zaug uas yuav tsum tau ua thaum mus kev deb. Koj tseem tuaj yeem sim ua lwm yam "koob":
- ntawv ntawv
- Rab chais hniav
- Tus Pin
- plaub hau clips
Kauj Ruam 2. Xaiv rab koob "hlau nplaum"
Koj tuaj yeem siv rab koob sib nqus ntau txoj hauv kev: kov nws nrog hlau lossis hlau, txhuam nws nrog cov hlau nplaum, lossis txhuam nws nrog lwm yam khoom los nqus nws nrog hluav taws xob zoo li qub.
- Koj tuaj yeem siv cov hlau nplaum hauv tub yees, uas tseem tuaj yeem yuav hauv khw muag khoom siv tes ua.
- Koj tuaj yeem siv cov hlau lossis hlau ntsia hlau, tus nees nees, tus neeg coob, lossis lwm yam khoom siv hauv tsev yog tias koj tsis muaj hlau nplaum.
- Txhob lo lo ntxhuav thiab plaub kuj tseem tuaj yeem siv los nqus cov koob.
- Yog tias txhua yam ua tsis tau, sim siv koj cov plaub hau.
Kauj Ruam 3. Sau cov khoom seem uas seem
Ntxiv nrog rau rab koob thiab hlau nplaum, koj yuav xav tau ib lub tais me me, dej thiab cork.
Ntu 2 ntawm 3: Ua Compass
Kauj Ruam 1. Magnetize koj rab koob
Rub cov hlau nplaum tawm tsam cov khoom koj tab tom siv, txawm nws yog rab koob xaws lossis lwm yam khoom siv hlau. Rub rab koob nyob rau hauv ib qho kev taw qhia, tsis yog rov qab thiab tawm mus, hauv qhov khov kho, txawm tias txav mus los. Tom qab 50 tus cwj nrag, rab koob yuav tsum tau magnetized.
- Siv tib txoj hauv kev los nqus cov koob nrog txhob lo lo ntxhuav, plaub tsiaj, lossis plaub hau. Rub rab koob nrog ib qho ntawm cov khoom 50 zaug kom txog thaum nws dhau los ua cov hlau nplaum. Tsis txhob siv txoj kev no yog tias koj siv rab chais hniav.
- Yog tias koj tab tom nqus cov koob nrog ib daim hlau lossis hlau, coj mus rhaub rau ntawm rab koob kom nqus tau nws. Ntxig lub koob rau hauv cov ntoo thiab ntaus sab saum toj ntawm rab koob 50 zaug.
Kauj Ruam 2. Ntxig lossis tso rab koob rau hauv/ntawm lub cork
Yog tias koj siv rab koob xaws, xov nws kab rov tav rau hauv qhov txiav ntug ntawm lub cork kom lub koob hla lub cork thiab tawm mus rau lwm sab. Laub rab koob kom txog thaum qhov ntev tawm ntawm ob sab ntawm lub cork yog tib yam.
- Yog tias koj siv rab chais rab riam lossis lwm hom koob, cia li muab nws tso rau hauv nruab nrab ntawm lub cork. Koj yuav xav tau ib daim cork loj los tuav rab chais hniav.
- Txhua yam khoom ntab me me tuaj yeem siv tsis tau cov npib cork. Yog tias koj nyob nraum zoov thiab xav tau qee yam kom ntab rab koob, siv nplooj ntoo.
Kauj Ruam 3. Ntab lub compass
Sau lub tais lossis lub tais nrog dej kom siab li ob peb centimeters thiab tso tus pas ntsuas kub saum cov dej. Cov koob hlau nplaum yuav hloov kho rau lub ntiaj teb cov chaw sib nqus thiab taw tes rau sab qaum teb-qab teb.
- Koj lub ntsuas hluav taws xob yuav muaj lub sijhawm nyuaj taw rau sab qaum teb-qab teb nyob rau hauv qhov cua daj cua dub. Sim tiv thaiv rab koob los ntawm cua los ntawm kev siv lub tais siab lossis lub thawv.
- Cov dej hauv dej kuj tseem yuav cuam tshuam nrog cov lus qhia hauv lub koob. Yog li, tsis txhob cia siab tias lub ntsuas hluav taws xob qhia qhov kev taw qhia kom raug yog tias koj ntab cov pas ntsuas hauv pas dej lossis pas dej. Peb pom zoo kom koj siv cov dej uas sawv ntsug.
Ntu 3 ntawm 3: Nyeem Compass
Kauj Ruam 1. Txheeb xyuas tias rab koob yog hlau nplaum
Cov ntab ntab thiab cork lossis nplooj yuav tsum tig maj mam taw tes rau sab qaum teb-qab teb. Yog tias koj lub ntsuas hluav taws xob tsis txav mus, rub los yog coj mus siv rab koob kom nws nqus tau.
Kauj Ruam 2. Nrhiav sab qaum teb
Txij li cov koob txhaj tshuaj sib kis rau sab qaum teb-qab teb, koj tsis tuaj yeem siv nws los saib rau sab hnub tuaj lossis sab hnub poob txog thaum koj pom sab qaum teb. Siv ib qho ntawm cov txheej txheem hauv qab no los txiav txim rau sab qaum teb, tom qab ntawd kos tus ntug ntawm lub ntsuas phoo nrog tus cwj mem lossis tus cim kom koj tuaj yeem siv nws los txiav txim siab lwm cov lus qhia tseem ceeb:
- Nyeem cov hnub qub nyob qhov twg. Nrhiav North Star, uas yog lub hnub qub kawg hauv kev tuav ntawm Me Me Dipper constellation. Xav txog ib txoj kab txuas los ntawm North Star mus rau hauv av. Cov kev taw qhia kab yog taw tes yog sab qaum teb.
- Siv txoj kev ntxoov ntxoo. Muab tus pas txiav rau qhov av. Kos rau qhov chaw uas tus pas nrig tus duab ntxoov ntxoo ntog nrog pob zeb. Tos 15 feeb, tom qab ntawd kos tus duab ntxoov ntxoo ntawm qhov ntxeev ntawm tus pas nrog pob zeb thib ob. Txoj kab txuas ob lub pob zeb yog ntxhab sab hnub tuaj-sab hnub poob. Yog tias koj sawv ntawm sab xis ntawm thawj pob zeb thiab sab laug ntawm pob zeb thib ob, koj tab tom tig mus rau sab qaum teb.
