Maabara mtandaoni yanawapa wanafunzi wako uwezekano wa kuendesha majaribio ya kisayansi katika mazingira ya mtandaoni. Maabara yanayoendeshwa kwa mbali (maabara ya mbali) yanakupa fursa ya kujaribu mitambo halisi kutoka sehemu za mbali. Maabara ya mtandaoni yanapatia uhai mtambo ya kisayansi. Mipangilio ya data inawasilisha data kutoka katika majaribio ya maabara yaliyofanywa awali. Tafadhali tumia vichujio kwenye upande wa kulia ili kupata maabara mtandaoni yanayofaa darasa lako. Maabara yanaweza kuunganishwa kwa Programu tumizi maalum ili kuunda Nafasi za Kusoma za Kiulizio(ILSs).
Ikiwa unatafuta maabara ya mtandaoni hasa yanafaa kwa somo la Benin, Kenya au Nigeria, tafadhali tembelea ukurasa wetu wa Makusanyo.

Unajuaje kama Mlinganyo kemikali ni uwiano? Nini unaweza kubadili kusawazisha Mlinganyo? Kucheza mchezo mtihani mawazo yako!
Malengo ya msingi ya maabara:
Na maabara hii utapata nje jinsi mgawanyo wa mchanganyiko ni kufanyika kwa kutumia mbinu zifuatazo:
Kutenganisha mpare
Chromatography
Centrifugation
Kutonesha rahisi
Fractional kutonesha
Kuchunguza shinikizo katika kiwango cha atomic. Kila jambo ni alifanya juu ya atomi, ambayo yanafanya molekuli. Atomi na molekuli hizi ni daima katika mwendo. Wakati atomi na molekuli zilizomo, tunaweza kupima kiasi cha shinikizo la wao kuweka kwenye kontena hilo.
Kuchunguza maingiliano kusababisha maji na mafuta ya tofauti kutoka kwa mchanganyiko. Mafuta ni molekuli yasiyo ya polar, wakati maji ni molekuli polar. Wakati molekuli wote wanavutiwa kwa kila mmoja, Vivutio baadhi ni imara zaidi kuliko wengine.
Dhamana (kutoka kufahamiana katika kemia) husaidia wanafunzi kujifunza kuhusu solubility na precipitation ya chumvi. Dhamana ina database na maelfu ya chumvi na ions kawaida, na maelezo kuhusu solubility na rangi. Usanidi wa ni sawa na wanafunzi angefanya nini katika maabara ya kemia halisi.
Lengo letu ni kujifunza tofauti ya uwezo wa seli wa Zn│Zn2 + ││Cu2 + │Cu seli na mabadiliko katika mkusanyiko wa elektroliti (CuSO4 na ZnSO4) katika chumba cha joto. Wanafunzi kuelewa masharti, electrochemical seli, seli ya electrolytic, Daniell seli, daraja ya chumvi, EMF.
Masimulizi hii inaruhusu taswira mchakato wa dissociation ya natrium kloridi katika maji.
Katika shughuli hii, wanafunzi kutumia maabara virtual kujenga ufumbuzi wa hisa kuanzia chumvi imara. Wanafunzi lazima kwanza mahesabu ya kiasi sahihi ya imara kufanya ufumbuzi. Kisha, huandaa suluhisho kwa kutumia kioo sahihi.
Simulation hii inaruhusu wanafunzi kufanya mara mbili hisia za makazi kwa kutumia sodiamu kiberiti na ufumbuzi Bari kloridi.
