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.

Je unashangaa jinsi gesi na chafu huathiri hali ya, au kwa nini tabaka la ozone ni muhimu? Matumizi sim kuchunguza jinsi mwanga kuingiliana molekuli katika mazingira yetu.
Kwa nini puto fimbo na sweater yako? Kusugua puto juu ya sweater, basi hebu kwenda kwenye puto na nzi juu na vijiti kwa sweater. Angalia mashtaka katika sweater, balloons, na ukuta.
Malengo ya kujifunza
Maabara hii inatoa wigo wa mionzi eletormagnetic katika suala la urefu wimbi na marudio.
Mweupe ingiliani shughuli ambapo wanafunzi kujenga chembe kwa kuburuta elektroni, neutrons na protons kwenye kiolezo. Elementi taarifa kisanduku inaonyesha kama ni sahihi. Uhuishaji pia inaweza kutumika kwa kuonyesha jinsi ions fomu.
Kuchunguza aina mbalimbali za vivutio kati ya molekuli. Wakati molekuli wote wanavutiwa kwa kila mmoja, Vivutio baadhi ni imara zaidi kuliko wengine.
Kuchunguza nini kinatokea katika ngazi ya Masi wakati mabadiliko awamu. Tatu kawaida kimwili majimbo ya jambo (pia huitwa awamu) ni imara, kioevu na gesi. Jambo kubadilisha awamu na Aidha au ya joto. Molekuli ni daima katika mwendo.
Kuchunguza nini kinatokea wakati nguvu kutumika kwenye nyenzo kauri. Kuna aina nyingi tofauti za vifaa. Kila nyenzo ina muundo Masi fulani, ambao ndio wenye dhamana kwa ajili ya sifa za mitambo na vifaa.
Wakati molekuli wote wanavutiwa kwa kila mmoja, Vivutio baadhi ni imara zaidi kuliko wengine. Molekuli visivyo polar wanavutiwa kupitia London utawanyiko kivutio; molekuli ya Polar wanavutiwa kupitia London utawanyiko nguvu na mvuto wa dipole-dipole imara.
