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.

Workbench hii mtandaoni inaruhusu kuamua mkusanyiko wa tindikali nguvu isiyojulikana na kuangalia majibu. Wanafunzi wanaweza kutumia matoleo ya mtandaoni ya vifaa vya maabara kufanya majaribio yao.
Kuchunguza miundo ya molekuli kwa kujenga molekuli katika 3D! Kujua jinsi ya molekuli umbo mabadiliko kama Ongeza atomi katika molekuli ya.Malengo ya msingi ya maabara ni:1) Recognize kwamba sura ya molekuli ni kutokana na repulsions kati ya atomi
Kuchunguza miundo ya molekuli kwa kujenga molekuli katika 3D! Jinsi umbo molekuli kubadilika na idadi tofauti ya vifungo na jozi ya electron? Kujua kwa kuongeza moja, mara mbili au mara tatu vifungo na majozi lone atomi kati. Kisha, Linganisha mfano wa kuigwa kwa molekuli halisi!
Atomi yote ya kipengele ni sawa? Je, unawezaje kuwaambia Isotopi moja kutoka kwa mwingine? Kutumia sim ya kujifunza kuhusu isotopes na jinsi wingi inahusiana na atomia wastani wa kipengele.
"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:
Jinsi gani Rutherford kufikiri muundo wa atomi ya bila kuwa na uwezo wa kuona? Igiza majaribio maarufu ambayo yeye disproved mfano saladi ya Plum wa atomi ya kwa kuchunguza chembe alpha bouncing mbali atomi na kubaini kwamba lazima kuwa na msingi ndogo.
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.
Maabara hii husaidia kuelewa vyema matukio yafuatayo:Uwezo wa mwingilianoKufahamiana atomicVan der Waals nguvu
Kujenga chembe nje protons, neutrons na elektroni, na kuona jinsi elementi, malipo, na mabadiliko ya molekuli. Kisha kucheza mchezo mtihani mawazo yako!
