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.

Asidi ya nguvu na kuwa dhaifu tofauti gani? Kutumia zana za maabara kwenye tarakilishi yako ili kujua! Kuzamisha karatasi au uchunguzi wa katika ufumbuzi kupima PH ya udongo, au kuweka katika electrodes kupima conductivity ya. Kisha angalia jinsi ukolezi na nguvu huathiri pH.
Lengo la masimulizi ni kuandaa mchanganyiko na kutumia kiwanja chuma viingilio na kiberiti poda na kutofautisha kati ya haya juu ya msingi wa:
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.
Maabara hii inakuruhusu kufanya majaribio ambayo itakusaidia kuelewa sifa za asidi na Besi.
Mfano kusaidia kuonyesha ufunguo mambo kuathiri viwango vya majibu. Si mzuri kwa ajili ya kizazi cha viwango vya data lakini husaidia wanafunzi visualise michakato ya.
"Kioo mazito ya pombe darker, chini ya nuru hupitia." Kufanya ufumbuzi rangi ya kujilimbikizia na kuondokana na kuchunguza kiasi mwanga kunyonya na kusambaza kutumia spectrophotometer pepe!Malengo ya msingi:
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.
Zoezi la kubuni suluhisho la buffer na mali maalum.
