ib yam uas piav txog qhov teeb meem. Pawg . Tus nqi ntawm cov teeb meem hauv ib yam khoom, Matter. Txhua yam uas muaj pawg thiab siv qhov chaw.
Ib yam li ib tug yuav nug, qhov ceev hauv science qib 6 yog dab tsi?
Qhov ntom yog ib lo lus uas peb siv los piav txog qhov chaw ntau npaum li cas ib yam khoom lossis cov khoom siv (nws ntim) ntsig txog qhov muaj pes tsawg leeg ntawm cov khoom ntawd lossis cov khoom (nws qhov loj). Yog li, yog tias peb paub qhov ntim thiab qhov loj ntawm ib qho khoom, peb tuaj yeem suav qhov ceev siv qhov sib npaug ceev = loj / ntim.
Tom qab ntawd, lo lus nug yog, dab tsi yog qhov loj hauv science? Pawg yog ib qho kev ntsuas ntawm tus nqi ntawm cov khoom hauv ib yam khoom. Pawg feem ntau yog ntsuas hauv grams (g) lossis kilograms (kg). Pawg ntsuas qhov muaj nuj nqis ntawm cov teeb meem tsis hais nws qhov chaw nyob hauv lub ntiaj teb thiab lub zog gravitational siv rau nws. Koj pawg nyob ntiaj teb thiab lub hli yeej zoo ib yam.
Yog li ntawd, qhov ntim hauv science qib 6 yog dab tsi?
Ntim . Tus nqi ntawm qhov chaw uas ib yam khoom lossis khoom siv nyob. Meniscus. Curved nto ntawm kua. Nco ntsoov nyeem hauv qab ntawm lub meniscus.
Dab tsi yog qhov hnyav thiab qhov hnyav hauv science?
Nyob rau hauv scientific ntsiab lus, pawg yog tus nqi ntawm "teeb meem" nyob rau hauv ib yam khoom (txawm hais tias "teeb meem" tej zaum yuav nyuaj rau txhais), whereas hnyav yog lub zog exerted rau ib yam khoom los ntawm lub ntiajteb txawj nqus. Cov khoom nyob rau saum npoo ntawm lub ntiaj teb muaj hnyav , txawm tias qee zaum cov hnyav yog qhov nyuaj rau ntsuas.

Cov ntsiab lus science qib 7 yog dab tsi?
Txawm hais tias tsis muaj ib qho kev qhia tshwj xeeb ntawm kev kawm ntawm qib 7th-kev tshawb fawb, cov ntsiab lus ntawm kev tshawb fawb txog lub neej muaj xws li kev faib tawm scientific; cell thiab cell qauv; heredity thiab noob caj noob ces; thiab tib neeg lub cev thiab lawv txoj haujlwm
Dab tsi yog cov ncauj lus hauv kev ua lej hauv tsev kawm qib siab?
Cov ntsiab lus tseem ceeb uas tau qhia hauv chav kawm no yog teeb tsa txoj kev xav, lub cim logic, geometry thiab kev ntsuas, kev qhia txog kev sib txuas lus, qhov yuav tshwm sim thiab piav qhia cov txheeb cais, thiab keeb kwm ntawm lej
Lub zog hauv science rau Qib 5 yog dab tsi?
Lub zog yog lub peev xwm ua haujlwm. Koj xav tau lub zog los yuam kom ib qho khoom txav mus. Koj xav tau lub zog los hloov qhov teeb meem. Cov cua tshuab, lub hnub sov so thiab nplooj poob yog tag nrho cov piv txwv ntawm lub zog siv
Dab tsi feem ntau yog pab pawg ua haujlwm thiab vim li cas cov pab pawg no tseem ceeb?
Cov pab pawg ua haujlwm tau txuas mus rau carbonbackbone ntawm cov organic molecules. Lawv txiav txim siab tus yam ntxwv thiab tshuaj lom neeg reactivity ntawm molecules. Cov pab pawg ua haujlwm tsis tshua muaj kev ruaj ntseg dua li cov pa roj carbon monoxide thiab zoo li yuav koom nrog cov tshuaj tiv thaiv
Qib kev ntsuas rau qib kev zoo siab yog dab tsi?
kev cai Hais txog qhov no, qhov ntsuas kev zoo siab yog dab tsi? Yooj yim muab tso, kev noj qab nyob zoo yog txhais raws li koj qhov kev ntsuam xyuas ntawm a) koj tus kheej lub neej, thiab b) koj lub siab xav thiab kev xav-li no daim ntawv lo "
