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.
Kemia
Panga kwa
Na maabara hii utapata nje jinsi mgawanyo wa mchanganyiko ni kufanyika kwa kutumia mbinu zifuatazo:
Kutenganisha mpare
Chromatography
Centrifugation
Kutonesha rahisi
Fractional kutonesha
Maabara hii itakusaidia kujifunza jinsi ya kujenga molekuli isokaboni. Pia utaweza kuchunguza asili ya vifungo kati ya atomi na jinsi elektroni kuwekwa.
Lengo la masimulizi ni kuandaa mchanganyiko na kutumia kiwanja chuma viingilio na kiberiti poda na kutofautisha kati ya haya juu ya msingi wa:
Methyl machungwa ni rangi ya Chungwa, azoic na hutumika kama pH-kiashiria, na mpito kutoka 3.1 kwa 4.4 pamoja dyeing na uchapishaji nguo. Katika maabara hii mbali wanafunzi wanaweza kuchunguza dhana methyl machungwa.
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.
Kufanya mtihani iodini na vitu tofauti chakula kwa mtihani wa uwepo wa wanga.
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.
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.
