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.

Mtindo huu ni masimulizi ya kulingana na wakala watu genetics. Programu ina zana kufanya majaribio virtual kukiuka dhana ya nadharia ya Hardy-Weinberg (idadi ndogo, uteuzi, walivyoelezea, uhamiaji na yasiyo ya nasibu kujaminiana).

Maabara hii inaweza kutumika kwa kufahamu dhana ya uzalishaji wa umeme katika mtambo wa osmotic. Unategemea mfano rahisi wajumuisha vigezo kijiografia. Wanafunzi wanaweza kuchagua mahali pa mtambo wao osmotic na Linganisha kwa mfano huko Norway.

Mtindo huu simulates mfano uteuzi wa asili katika rangi ruwaza katika peppered moths (Biston betularia). Wakati uchafuzi wa hewa ni chini, lichens kufunika miti na moths mwanga ni vizuri udanganyifu unaofanywa kwa siri. Wakati uchafuzi wa hewa ni juu, miti kuwa giza na moths mwanga kusimama nje.
