Chidwi Science: mmene mungagwiritsire zinachitikira kunyumba umagwirira choti mwanayo?

Mu sekondale, anayamba umagwirira mpaka grade 8, chovuta kutenga izi ana sayansi. Koma kukonzekera wophunzira nkhani kungakhale ndithu kusangalala ndi zophweka - ndi kukonza zambiri umagwirira kunyumba. Izi mini-zatsopano kudzakuthandizani kuyang'ana sayansi Komano, bwanji za "Chemical zidule" pa phwando ana kwambiri kuonjezera digiri zosangalatsa.

fireproof bilu

Kuchita amazipanga chidwi koma losavuta tsenga, muyenera:

• bilu;
• amadzimadzi mowa njira ndi okhutira ndi mowa pafupifupi 50%;
• mchere;
• forceps kapena tweezers.

A uzitsine mchere ayenera zidzawonjezedwa kwa njira. Kenako mu njira ntchito tweezers anaika bilu. Anthu amene kwa nthawi yoyamba akugwirizira zoterezi zambiri zimapangidwira, ndi bwino kutenga ang'onoang'ono bilu ulemu!

Kamodzi ndalama ndi vymoknut zabwino, iwo ayenera kunyamula tweezers ndi modekha sansani madzi owonjezera ndi pepala. Tsopano n'zotheka potentha! Moto zidzachitika mu bilu koma palibe amene m'mphepete ngakhale browns. Ichi ndi chifukwa mowa moto ali njira. Nawonso madzi amene akhathamiritsa pepala alibe nthawi asanduke nthunzi.

nsupa

Crystal kukula - mmodzi wa masewera otchuka, amene amapereka umagwirira zimasangalatsa. Zatsopano ndi crystallization zambiri timathera shuga, koma makhiristo shuga sizachilendo. Tikupereka pamaso latsopano ndi zachilendo - timibulu atakula pa mazira!

nsupa akhoza akamagwira:

• alum (chogulitsidwa pharmacies);
• PVA zomatira;
• utoto.

The makhiristo pa mazira kukula mofulumira kwambiri, mu tsiku. M'pofunika Pre-kusamba zipolopolo bwinobwino ndi kupukuta izo. Kenako mazira topaka zomatira ndi kuwaza alum. Tsopano ayenera kugona kwa maola ochepa kuti ziume kachiwiri.

Komanso, utoto ayenera zidzasungunuka mu makapu awiri madzi opanda. Kuchuluka kwa utoto akhoza anasankha paokha, mu nkhani iyi, koma mphamvu ya mtundu zimatengera timibulu kwa izo. mazira anayikidwa mu utoto tsiku kapena usiku. The yaitali dzira lagona pa njira makhiristo Nthiti zimacheperapo. Konzekani mazira galasi azitha - iwo ndi osalimba kwambiri.

Zibaluni pa botolo

Monga mmene mpweya zibaluni popanda helium popanda kuchita khama thupi? Kuti tichite zimenezi, mukhoza kugwiritsa ntchito wamba soda ndi vinyo wosasa, amene kuima m'kabati m'khitchini lililonse amayi. Kuchita kuyesera mu zimapangidwira, adzafunika:

• ndi zibaluni;
• botolo;
• 3-4 teaspoons wa koloko;
• viniga.

Koloko anatsanulira mwachindunji mu mpira ndi thandizo la nyuzi kapena supuni. Pambuyo umene kuvala botolo ndi pang'ono vinyo wosasa. Pamene koloko mpira wayamba kudzuka botolo, iwo amayamba pathupi, ngati helium. Ichi ndi chifukwa chakuti viniga ndi anachitira ndi koloko, kumasuka mpweya. mpira ndi mpweya chifukwa mpweya masekondi angapo okha ndi kugwira!

zigawo Mipikisano wachikuda mu botolo

The kuyesera lotsatira umagwirira mwana kufotokoza momveka bwino mfundo osalimba a madzi. Zosowa izi:

• kotala chikho cha mafuta mpendadzuwa;
• kotala chikho cha madzi, zosasonyeza mtundu wake weniweni mtundu uliwonse yowala;
• kotala chikho cha shuga madzi (kwa cholinga zothandiza, izo ndi zofunika kuwonjezera utoto).

Mwana akhoza kuganiza zimene zidzachitike pamene kusakaniza onse zakumwa izi. Iye monga chotsatira - madzi zikukhazikitsa pansi monga yowirira kwambiri, madzi ndi pakati, ndi mafuta adzatsala pamwamba. Mukhoza kuyetsa mitundu ndi madzi, kupanga sangaganize zikuchokera. Mwachitsanzo, powonjezera milingo yosiyanasiyana ya shuga mu madzi, adzakhala kupeza ena zakumwa ya machulukidwe osiyana.

Laboratory mayesero mu umagwirira kungakhale ndithu si kosangalatsa. Ochititsa chidwiwa koma yosavuta zidule kuthandiza amakopa mwana kuphunzira sayansi ndi chabe kusangalatsidwa pa tsiku la mvula.
