Scientific Method hi eng nge ni tak tak?
A awlsam zawngin sawi ila, scientific method hi kan chhehvela thil kan hmuhte chhui chian a, chutiang chungchanga zawhna chhanna kan hmuhna atana kan hman dan tur ruahmanna felfai tak, mumal tak a ni. Hei hi a chang chuan ‘hypothetico-deductive method’ an ti a, mahse chu hming chuan bum che suh.
Hetiang hmanrua kan hman huna kan thil tum ber chu:
- Kan thil hmuh chungchanga zawhna zawh leh a chhan leh a rah chhuah inzawmna zawng chhuah tum .
- Kan thil hmuhchhuah chungchangah hian a theih ang anga finfiahna khawlkhawm . He finfiahna hian kan zawhna chhânna hmu tûrin min ṭanpui ang.
- A tawp berah chuan heng evidence kan khawlkhawm zawng zawng hi kan dah khawm a, kan zawhna chhanna dik tak kan siam thei ang em tih kan en a ni.
Philosopher Francis Bacon leh Rene Descartes te chu kum zabi 16 leh 17-naah he method hi formalise-a siamtu an ni. Anni chuan zirchianna chu ngaihdan siam lawk a\anga kalpui ni lovin, thil dik tak dik tak (logically examining) hmanga tih tur a ni, tiin an sawi.
Scientific method hmanga step te chu engte nge ni?
Scientific method hi harsatna sutkian dan step by step a ni. Hemi kawngah hian kan zawm tur pawimawh tak tak a awm. Hriatthiam awlsam takin han thlir ila.
| Step hrang hrang | A awlsam zawngin... |

| 1. Enfiahna | I chhehvel khawvel ngaihven. Hetah hian i tan harsatna a lo chhuak thin. I rilruah harsatna i nei tawh maithei. Chumi chungchâng lehkhabu tam zâwk i chhiar a ngai a, mi dangte i zawt a, hriatna i neih a ngai bawk. |
| 2. Zawhna zawh | I thil hmuh chungchangah zawhna zawh, "Engvangin nge hetiang hi a lo awm?" "Engtin nge he thil hi a lo thlen?" He zawhna hi a chiang hle a ngai a ni. Tin, experiment-a i thlak danglam theih tur (variable) leh i teh theih tur thil i neih a ngai bawk. |
| 3. Hypothesis siam | I zawhna chhangtu educated guess , "Hei hi hetiang thil hi a thlen chhan pawh a ni mai thei." Hei hi hypothesis kan ti a. Hypothesis tha tak chu a dik lo a nih chuan a dik lo tih finfiah theih a ni. |
| 4. Checking tih a ni | I hypothesis dik leh dik loh test nan. A chang chuan test theih loh chuan enfiah leh data khawlkhawm a ngai thin. Experiment pakhat result hi thil thleng mai mai a nih theih avangin vawi tam tak test a tha zawk . |
| 5. Thutlukna siam | Experiment atanga data te thlirlet a, i hypothesis dik leh dik loh thutlukna siam. I hypothesis dik lo a nih chuan hypothesis thar siam nan i hmang thei ang. |
| 6. Results insem darh | Scientific research hi mahni chauha tih tur a ni lo. I thil hmuhchhuahte chu midangte hnena i sawi chhuah a ngai a ni.

Zing lama chhang toast turin toaster-ah chhangphut slice pahnih i dah a, button i hmet a, mahse engmah a thleng lo ang tih han ngaihtuah teh. Toaster chuan hna a thawk lo! Tunah chuan scientific method hmangin he harsatna hi chingfel ila.
- Observation: Ka toaster hian hna a thawk lo.
- Zawhna: Engvangin nge he toaster hian hna a thawh loh?
- Hypothesis: Toaster ka plug na power outlet ah hian thil dik lo a awm mai thei.
- Prediction: Chuvangin, plug point dang i plug chuan toaster hian hna a thawk tur a ni.
- Test: Toaster chu i unplug a, kitchen chhunga plug point dang ah i plug a.
- Thutawp: Chu plug point-a i plug lai khan toaster chu a thawk ta ang u. Tichuan i hypothesis chu a support ta a ni . Chu chu a dik theihna chance tha tak a awm tihna a ni. Mahse toaster chu a la thawk lo a nih chuan i hypothesis chu a dik lo tihna a ni .
- Next step: Toaster hian hna a thawk lo a nih chuan hypothesis thar i siam chhuah a ngai a ni. Entirnan, "Toaster wiring-ah hian thil dik lo a awm mai thei." Tichuan technician hnenah i check tir thei ang.
- Results insem: Hetiang thil tenau tak hi research paper ziah a ngai lo a nih pawhin, i chhungte hnenah, "Chu plug point chu a thawk lo, engmah plug suh," tiin i hrilh thei ang. Chu pawh chu hriatna insemna a ni.
