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.

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.
Wanafunzi kufanya kazi katika umbali katika ILSs mbili tofauti kushiriki masimulizi ya Jenitikia ya Sungura. Mabadiliko yaliyofanywa katika toleo moja la masimulizi kwa wakati huo huo huonyeshwa katika toleo la.
Chunguza jinsi nakala ya mRNA ya DNA imetengenezwa. Protini complexes tofauti ya DNA helix kuruhusu zaidi mRNA nucleotides kwa kumfunga mlolongo wa DNA. Jozi ya nucleotides ni maalum sana.Lengo la msingi la maabara ni:1) kujifunza kuhusu DNA na nucleotides
Mtindo huu ni wa urekebishaji wa majaribio classic uliofanywa na Buri wa Peter (1956), ambayo kumbukumbu drift chembe za damu katika idadi ya maabara ya Drosophila.
Kuchunguza maingiliano ya jinsi hydrophobic na hydrophilic kusababisha protini mara katika maumbo maalum. Protini, alifanya juu ya amino asidi, hutumiwa kwa madhumuni mengi tofauti katika seli. Seli ni mazingira yenye maji (maji ya kujazwa).
Maabara hii ni kutumika kujifunza kiwango cha upumuaji katika mimea mbegu kuwa na dutu tofauti kama vile ngano (wanga), haradali (mafuta) na maharage (protini).
Maabara hii, kupitia kuunda na majaribio, inaonyesha kwamba dioksidi ya kaboni iliyotolewa wakati wa upumuaji aerobic. Maabara hii pia inaweza kutumika kujifunza athari ya joto kwa kiwango cha upumuaji.
Masimulizi hii visualizes jicho tofauti madhara, kama vile astigmatism, hyperopia na kukosa, na jinsi wao vinaweza kuwekwa na aina tofauti ya lenses ya kioo.
