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.

Maabara hii inaruhusu wanafunzi kutazama aina tofauti za molekuli kuunda imara, kioevu, au gesi.
Jaribu pH ya mambo kama kahawa, mate, na sabuni kuamua kama kila tindikali, msingi, au upande wowote. Piga twasira ya nambari ya jamaa ya hydroxide Ions na hydronium Ions katika ufumbuzi. Badilisha kati ya Skeli logarithimiki na mizani ya mstari.
Kutumia GoLab molekuli wajenzi unaweza kuchunguza sifa na asili ya molekuli 20 tofauti ya kikaboni.
Stirio molekuli Kionyeshi cha mradi, molekuli ni inayotolewa katika mazingira ya 3d, makadirio katika 3d kutumia geowall ya. Apuleti ya pia Zungusha, Kuza, kutafsiri, na kupima sehemu nyingi za molekuli ya.
Ukaushaji inaeleza jinsi chembe ya jambo hoja kupitia viowevu vingine na gesi (ikiwa ni pamoja na hewa). Ukaushaji anaelezea jinsi umati wa chembe na joto ni kuhusiana na jinsi haraka chembe kuenea nje juu ya eneo.
Mtihani pH ya vitu kama kahawa, mate, na sabuni ili kuamua kama kila ni tindikali, msingi, au upande wowote. Taswira idadi jamaa ya hydroxide ions na hydronium ions katika ufumbuzi. Kubadili kati ya mizani Logariti na mstari.
Pampu ya gesi molekuli kwenye sanduku na kuona nini kinatokea kama wewe mabadiliko ya kiasi, kuongeza au kuondoa joto, na zaidi. Kupima joto na shinikizo, na kugundua jinsi mali ya gesi hutofautiana katika uhusiano na kila mmoja.
Michoro hii inaonyesha ngozi mnururisho wa miali fiche butu kwa CO2 katika troposphere ya na collisional kukosa nishati hii kufyonzwa kwa jirani N2 na O2 ya molekuli. Katika uhuishaji hii mtumiaji anaweza kufagia kupitia mkoa wa IR na excite baadhi ya namna vibrational za CO2.
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.
