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.
Kujenga chembe nje protons, neutrons na elektroni, na kuona jinsi elementi, malipo, na mabadiliko ya molekuli. Kisha kucheza mchezo mtihani mawazo yako!
Asidi ya nguvu na kuwa dhaifu tofauti gani? Kutumia zana za maabara kwenye tarakilishi yako ili kujua! Kuzamisha karatasi au uchunguzi wa katika ufumbuzi kupima PH ya udongo, au kuweka katika electrodes kupima conductivity ya. Kisha angalia jinsi ukolezi na nguvu huathiri pH.
Na maabara hii utapata nje jinsi mgawanyo wa mchanganyiko ni kufanyika kwa kutumia mbinu zifuatazo:
Kutenganisha mpare
Chromatography
Centrifugation
Kutonesha rahisi
Fractional kutonesha
Nini kinachoamua mkusanyiko wa suluhisho? Jifunze kuhusu uhusiano kati ya fuko, lita, na molarity kwa kurekebisha kiasi cha ujazo wa solute na ufumbuzi. Mabadiliko solutes kulinganisha tofauti ya misombo ya kemikali katika maji.
Dhamana (kutoka kufahamiana katika kemia) husaidia wanafunzi kujifunza kuhusu solubility na precipitation ya chumvi. Dhamana ina database na maelfu ya chumvi na ions kawaida, na maelezo kuhusu solubility na rangi. Usanidi wa ni sawa na wanafunzi angefanya nini katika maabara ya kemia halisi.
Unajuaje kama Mlinganyo kemikali ni uwiano? Nini unaweza kubadili kusawazisha Mlinganyo? Kucheza mchezo mtihani mawazo yako!
Malengo ya msingi ya maabara:
Kutumia ya kuita jina m kikaboni maabara ya olecules unaweza kuchagua kutoka kwenye orodha ya molekuli namba na mazoezi katika kuita jina yao.
Lengo letu ni kujifunza tofauti ya uwezo wa seli wa Zn│Zn2 + ││Cu2 + │Cu seli na mabadiliko katika mkusanyiko wa elektroliti (CuSO4 na ZnSO4) katika chumba cha joto. Wanafunzi kuelewa masharti, electrochemical seli, seli ya electrolytic, Daniell seli, daraja ya chumvi, EMF.
Jaribu pH ya mambo kama kahawa, mate, na sabuni kuamua kama kila tindikali, msingi, au upande wowote. Piga twasira ya nambari ya jamaa ya hydroxide Ions na hydronium Ions katika ufumbuzi. Badilisha kati ya Skeli logarithimiki na mizani ya mstari.
Katika shida hii ya kupunguza reagents, wanafunzi huchanganya pamoja ufumbuzi katika uwiano tofauti katika jaribio la kuzalisha suluhisho la mwisho ambalo lina bidhaa 1 tu.
