Kuj paub, cov piv txwv ntawm kev tshawb xyuas qhov project yog dab tsi?
Kev Tshawb Fawb Kev Ua Haujlwm Piv Txwv
- Cogon Nyom Cardboard Khoom noj khoom haus Ntim.
- Basella Rubra Biological Stain.
- Wastepaper thiab Coir nrog Okra Mucilage.
- Kab laug sab Silk Textile Fiber.
- Mollusk Plhaub-Based Adhesive li Mortar.
- Ua Hluav Taws Xob los ntawm cov txiv hmab txiv ntoo.
- Kev sim kom pom cov txiv hmab txiv ntoo twg tuaj yeem tsim hluav taws xob.
- Lub teeb me me (tsawg voltage, tsawg 2.
Ib yam li ntawd, koj ua li cas sau ib txoj haujlwm tshawb nrhiav kev tshawb fawb? A Kev Tshawb Fawb Txog Kev Tshawb Fawb (SIP) siv lub kev tshawb fawb txoj kev kawm thiab sim ib lub tswv yim txog yuav ua li cas ib yam dab tsi ua haujlwm.
Part 1 Employing the Scientific Method
- Nug ib lo lus nug.
- Tshawb nrhiav koj lub ntsiab lus.
- Tsim ib qho kev xav.
- Tsim koj qhov kev sim.
- Ua koj qhov kev sim.
- Sau thiab txheeb xyuas koj cov txiaj ntsig.
Tsis tas li ntawd, dab tsi yog cov ncauj lus zoo tshaj plaws rau cov haujlwm tshawb nrhiav?
Cov kev kawm dav dav rau cov haujlwm tshawb fawb suav nrog biology, chemistry, ib puag ncig, ntiaj teb kev tshawb fawb, physics, astronomy thiab lub neej txhua hnub. Cov tub ntxhais kawm yuav tsum mus txog qhov teeb meem thiab sim ib lub tswv yim (hypothesis), tshawb fawb lub ntsiab lus, teb cov lus nug thiab xav txog qhov kev kawm.
Dab tsi yog life science tshawb nrhiav qhov project?
Cov lub neej sciences muaj xws li biology, botany, entomology, thiab lwm yam strands kev kawm uas tshawb nrhiav tej yam muaj sia. Kev tshawb nrhiav tej yaam num siv lub kev tshawb fawb txoj kev pib nrog cov lus nug uas tuaj yeem tshawb nrhiav, tsim cov kev xav, ua qhov kev sim, sau thiab txheeb xyuas cov ntaub ntawv, thiab kos cov lus xaus.

Ib qho piv txwv ntawm kev xav hauv kev tshawb fawb yog dab tsi?
Piv txwv ntawm kev tshawb xav txog kev tshawb fawb yog: Issac Newton's "System of the World" uas yog thawj qhov kev xav hauv lub ntsiab ntawm physics. Einstein's Special Relativity thiab General Relativity. Darwin's Theory of Evolution by Natural Selection. Thermodynamics, txoj kev xav uas suav nrog plaub txoj cai ntawm Thermodynamics
Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Cov piv txwv ntawm kev sim ua yuam kev yog dab tsi?
Melting point tshwm sim los ntawm ib pawg ntawm kev sim siab yog ib qho piv txwv ntawm qhov kawg. Blunders ( yuam kev). Tib neeg yuam kev. Kev soj ntsuam qhov system yuav ua rau yuam kev. Kev ua yuam kev vim muaj kev cuam tshuam sab nraud. Tsis yog txhua qhov kev ntsuas muaj qhov ntsuas tau zoo. Qauv
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
