Umphumela wokushisa Kuyinto yemvelo evumela ukuthi Umhlaba ugcine izinga lokushisa elifanele ukuphila. Kodwa-ke, imisebenzi yabantu iyawuqinisa lo mphumela ngenxa yokukhishwa kwegesi amagesi angcolisayo, okudala imiphumela emibi kakhulu ngesimo sezulu sale planethi. Ukuqonda ukuthi lesi simo sisebenza kanjani kubalulekile, futhi enye yezindlela ezingcono kakhulu zokwenza kanjalo ukudlula ukuhlola kanye nemisebenzi yokufundisa elungiselelwe ngokukhethekile izingane kanye nabantu abasha. Ukuze uqonde kangcono lo mqondo, kuhle ukufunda mayelana yini edala umphumela we-greenhouse.
Lesi sihloko sethula iqoqo lokuhlangenwe nakho okusebenzayo okulula kakhulu ukuphindaphinda ekhaya noma ekilasini. Ngezinto ezilula, zansuku zonke, noma yimuphi uthisha noma umndeni ungasiza izingane ziqonde ukuthi uyini umphumela we-greenhouse, ukuthi udalwa kanjani, nokuthi kungani kubaluleke kangaka ukuqaphela umthelela wako.
Ukuhlolwa kwebhokisi lezicathulo: ukulingisa indawo ebamba ukushisa encane
Okukodwa kokuzivocavoca okuyimifanekiso kakhulu ukukhombisa ukuthi ukushisa kunqwabelana kanjani ebukhoneni be Amagesi abamba ukushisa kuhlanganisa ukusebenzisa a ibhokisi lesicathulo. Kungumsebenzi ofundisa kakhulu futhi ofanele ukwenziwa eqenjini noma ngabanye, njalo ngokugadwa kwabantu abadala.
Izinto ezidingekayo:
- Ibhokisi lezicathulo
- Ikhadibhodi
- Glue
- Ingilazi esobala noma ipulasitiki
- I-thermometer yemvelo
Okokuqala, i-cardboard ifakwe ngaphakathi kwebhokisi eyenza i-angle efanele, ngaleyo ndlela ihlukanise isikhala sangaphakathi. I-thermometer ibekwe ohlangothini olunomthunzi. Ibhokisi libekwe elangeni imizuzu engu-15 futhi izinga lokushisa liyaphawulwa. Bese umboza ngengilazi bese ulinda enye imizuzu engu-15. I-thermometer izokhombisa ukwanda okukhulu kwezinga lokushisa, iveze ukuthi ukushisa kubambeke kanjani ngaphakathi, okufana nendlela amagesi abamba ukushisa asebenza ngayo emkhathini, into ehlobene umphumela we-anthropogenic greenhouse.
Lokhu kuhlola kubonisa ngokucacile ukuthi izinto ezibonisa ngale zivumela kanjani ukukhanya ukuthi kudlule kodwa hhayi ukushisa, okubangela ukwanda kwezinga lokushisa ezindaweni ezivaliwe, njengoba kwenzeka ezingeni lomhlaba jikelele nge-carbon dioxide noma i-methane.
Ukwakha i-thermometer yasekhaya ukukala izinguquko ezishisayo
Indlela ejabulisayo nefundisayo yokwethula amagama afana nalawa izinga lokushisa, ukudluliswa kokushisa y amagesi angcolisayo ukwenza i-thermometer yasekhaya. Akusizi nje kuphela ukuqonda umphumela we-greenhouse, kodwa futhi wethula imiqondo eyisisekelo ye-physics ne-chemistry.
Izinto ezisetshenziswa umbhangqwana ngamunye:
- Amabhodlela epulasitiki amabili anezivalo
- Ama-straw amabili
- Utshwala
- udayi owuketshezi
- Ubumba
Gcwalisa ibhodlela ingxenye eyodwa kwezintathu ngotshwala bese wengeza umbala ukuze wenze uketshezi lubonakale. Utshani lube selufakwa esivalweni (ngaphandle kokuthinta phansi) bese luvalwa nge-plasticine ukuze kungangeni umoya. Ukuphakama koketshezi otshanini kumakwa njengereferensi.
Isinyathelo esilandelayo siwukubeka le thermometer esitsheni sepulasitiki esikhanyayo, usivale bese usibeka elangeni noma isibani esifudumele. Imiphumela iqhathaniswa nenye i-thermometer efanayo engekho ngaphakathi ebhodleleni. Ukwenyuka kwezinga lokushisa ngaphakathi kwesiqukathi kubonisa ukuthi ukushisa kuvalwa kanjani endaweni evalekile., belingisa isimo somhlaba wonke ngamagesi abamba ukushisa. Ukuze ujule kulo mqondo, ungabonisana umsuka wokufudumala kwembulunga yonke.
Ukuqhathanisa izimbiza ezimboziwe nezingamboziwe: isilingo sakudala
Lona ukuhlolwa okuqondile nokumelela kakhulu kwe-greenhouse effect, njengoba kusivumela ukuthi sibone ngezenzo umehluko oshisayo phakathi kwendawo ekhululekile nevaliwe.
Izinto ezidingekayo:
- Izimbiza ezimbili noma izimbiza
- Ama-thermometers amabili
- I-aluminium foil noma ukugoqa kwepulasitiki ukumboza enye yazo
- Umthombo wokukhanya (okungcono okwemvelo)
Ama-thermometers afakwa kuzo zombili izimbiza. Enye ishiywa ivuliwe kuyilapho enye imboziwe ukuze ilingise umoya obamba ukushisa. Zombili zichayeka ekukhanyeni futhi, ngemva kwesikhashana, izinga lokushisa liyahlolwa. Lesi sivivinyo sibonisa indlela i- ukushisa isiqhingi umphumela kungaba isici esibalulekile ekufudumaleni kwendawo.
Imbiza emboziwe ivamise ukuba nayo izinga lokushisa eliphakeme, njengoba ukushisa kugcinwa ngaphakathi. Le nqubo ikhiqiza futhi ngezinga elincane okwenzeka emkhathini woMhlaba lapho amagesi abamba ukushisa avimbela imisebe yelanga ebonisiwe ukuthi ingaphunyuli emkhathini.
I-Melting Ice Experiment: Imithelela Yezinga Lolwandle
Ngaphezu kokuqonda ukuthi iplanethi ifudumala kanjani, kubalulekile futhi ukukhombisa imiphumela ebonakalayo lokho kufudumala, njenge ukuncibilika kweqhwa nokukhuphuka kwamazinga olwandle. Lesi sivivinyo esilula sikwenza kucace lokhu.
Izinto zokwakha:
- Isiqukathi esisobala
- Isitsha noma isitendi esilingisa isiqhingi noma izwekazi
- Amanzi
- I-Ice
- Umaka noma itheyiphu yokunamathisela ukumaka amazinga
Isitsha sibekwe sibheke phansi ngaphakathi kwesitsha futhi kuthelwe amanzi kuze kube yilapho sivala ingxenye yesitsha. Bese kubekwa iqhwa endishini. Izinga lokuqala lamanzi limakwa futhi iqhwa lilindelwe ukuba lincibilike. Lokhu kuhlolwa kubalulekile ekuqondeni imiphumela yokufudumala kwembulunga yonke ezingeni lolwandle.
Njengoba iqhwa liphenduka amanzi, izinga liyakhuphuka, lilingisa okwenzeka emhlabeni. Lo mphumela unemiphumela emibi kakhulu ezindaweni ezisogwini. kanye nezindawo zokuhlala zezinhlobo ze-polar njengebhere elimhlophe.
I-Cloud in Jar Experiment: Ukwakhiwa Kwamafu nesimo Sezulu
Olunye ucwaningo olubukwayo nolunelukuluku yilolo lwe ifu esitsheni, okuvumela izingane ukuba zichaze ukuthi amafu akheka kanjani nokuthi iyini indima yawo ekulawuleni isimo sezulu.
Izinto ezidingekayo:
- Isitsha seglasi noma ingilazi
- Amanzi ashisayo
- Umdlalo
- Ipuleti elibandayo noma isikhunta sensimbi esineqhwa
Amanzi ashisayo athululelwa embizeni futhi anyakaziswa ngobumnene. Umuntu omdala ube eselayitha umentshisi, awucime, awufake phakathi kwembiza. Ngokushesha, vala ngesitsha esipholile. Kancane kancane kwakheka ifu elibonakalayo ngaphakathi. Lesi simo singahlotshaniswa ne- amafu anda e-Arctic.
Intuthu yokufanisa ikhiqiza izinhlayiya ezimisiwe, okuthi, lapho zixutshwa nomhwamuko futhi zishaya indawo ebandayo, zidale ukujiya. Lokhu kulingisa inqubo engokwemvelo yokwakheka kwamafu, nayo ethonywa ama-aerosol, ukungcola, nokushintsha kwesimo sezulu.
Lolu hlobo lokuzivocavoca lusenza sikwazi ukuchaza umehluko phakathi isimo sezulu nesimo sezulu, nendlela ukushisa okwandayo okukushintsha ngayo ukwakheka kwamafu, imvula neziphepho.
Ukufunda nokuqwashisa: ukuzindla ngesayensi
Amandla eqiniso alezi zivivinyo azikho nje kuphela kulokho ezikubonisa ngokubonakalayo, kodwa futhi nasemandleni abo okwenza khiqiza imibuzo futhi akhuthaze ukucabanga okujulile phakathi komncane. Kungani izinga lokushisa likhuphuka kangaka? Yini esiyenzayo engalungile njengomphakathi? Singawunciphisa kanjani umthelela wethu kwezemvelo? Ukuze uqonde kangcono lezi zindaba, kubalulekile ukwazi imiphumela yokuguquguquka kwesimo sezulu esizayo.
Kusemqoka ukuthi, uma ucwaningo selwenziwe, abafundi bacabange ngalo: Ukuthi zihlobana kanjani nokufudumala kwembulunga yonke, indima edlalwa amagesi abamba ukushisa nokuthi yiziphi izinyathelo esingazithatha emazingeni ngamunye kanye neqembu ukunqanda ukuguquguquka kwesimo sezulu.
Lezi zinhlobo zemisebenzi zisiza ukugxilisa izindinganiso zemvelo kusukela zisencane, ziguqule izingane zibe ama-agent oshintsho. Ngaphezu kwalokho, ilukuluku lesayensi liyakhuthazwa futhi ulwazi lwefiziksi, ibhayoloji, nesayensi yezemvelo luhlanganiswe ngendlela esebenzayo nejabulisayo.
Ukuhlanganisa umdlalo, ukubukela, kanye nokuhlola nokuqwashisa ngemvelo kuyindlela esebenzayo yokukhiqiza intshisekelo kanye nogqozi mayelana nenye yezindaba ezicindezela kakhulu zesikhathi sethu: ukulwa nokuguquguquka kwesimo sezulu.
Ukuhlola umphumela we-greenhouse ngokusebenzisa lezi zivivinyo kuyindlela ewusizo kakhulu yokufundisa isayensi kuyilapho ukhuthaza ukunakekelwa kweplanethi. Ngezinto ezifinyeleleka kalula kanye nezinqubo ezilula, into enjalo eyinkimbinkimbi ingachazwa ngendlela ejabulisayo, eqondakalayo, nejabulisayo kubo bonke ubudala. Imisebenzi evezwe lapha inikeza ukuqonda okucacile kokuthi ukushisa kunqwabelana kanjani ezindaweni ezivalekile, ukuthi amafu akheka kanjani, nokuthi kungani amazinga olwandle enyuka. Ziphinde zinikeze amathuba ezingxoxo, ukuhlaziya, kanye nokwenza okuthile ukuze kuvikelwe indawo ezungezile.
