Weka upya
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 ya Mtandaono
Panga kwa
Kufanya mtihani iodini na vitu tofauti chakula kwa mtihani wa uwepo wa wanga.
Kuchunguza jinsi ya kubadilisha mlolongo wa DNA inaweza kubadilisha ya amino asidi mlolongo wa protini. Protini ni linajumuisha masharti ya muda mrefu ya amino asidi. Protini ni coded kwa ajili ya katika DNA. DNA inaundwa na aina nne tofauti za nucleotides.
Maabara hii inaruhusu wanafunzi kuchunguza jinsi viumbe vilivyo na sifa tofauti huishi mawakala mbalimbali wa uteuzi ndani ya mazingira.
Majaribio ya 1961 classic mashindano ya Connell unaofuata. Unaweza kuchunguza niches msingi na barabara ya aina mbili ya barnacles, Chthamalus na Balanus. Aina moja wanaweza kukua kwa hatua mbalimbali kwa kina lakini inaweza kuwa outcompeted, wakati aina nyingine ni mdogo kwa mwamba wa kina.
Masimulizi hii visualizes utaratibu wa Ukaushaji kote utando semipermeable na husaidia kuchunguza wajibu wa jambo hili katika mwili utendaji.
Lengo letu ni kuonyesha majaribio kwamba mwanga ni muhimu kwa usanidinuru. Wanafunzi wanaweza kutofautiana umbali kutoka chanzo mwanga na rangi ya chujio.
Matokeo ya kujifunza
Kujua watu wangapi ni katika idadi ya watu inaweza kuwa muhimu. Unawezaje kuwaambia jinsi wengi ni wakati kuna wengi mno kuhesabu? Mtindo huu simulates bwawa la tadpoles.
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).
Masimulizi hii visualizes jicho tofauti madhara, kama vile astigmatism, hyperopia na kukosa, na jinsi wao vinaweza kuwekwa na aina tofauti ya lenses ya kioo.
