Interesting Science: sei kupedza musha ruzivo kemisitiri kuti kutifadza mwana?

Chesekondari, akatanga kemisitiri kusvikira giredhi 8, kuoma kutora ichi kuvana sayenzi. Asi kuti agadzirire mudzidzi nenyaya inogona kunyatsonanga kunakidza uye nyore nenzira - nekuronga ruzivo kemisitiri kumba. Izvi Mini-kuedza kuchabatsira kutarira nesayenzi Ukuwo, anovanza "Chemical mazano" panguva chevana bato chaizvo kuwedzera mwero mafaro.

fireproof bhiri

Kuti aite chinhu chinopa zvinoshamisa, asi nyore Wandinyengedzerei, unofanira:

• bhiri;
• aqueous-doro mhinduro ane doro zviri vanenge 50%;
• munyu;
• forceps kana tweezers.

A kwekushinywa munyu inofanira kuwedzerwa kuti chigadzikiso. Next iri mhinduro vachishandisa tweezers vakagovera bhiri. Avo vari kekutanga akabata chiitiko chakadaro kemisitiri, zviri nani kutora maduku bhiri chiremera!

Kana mari zvakanaka vymoknut, vanofanira zvakare kunhonga tweezers uye zvinyoronyoro zuzai zvakawandisa zvokunwa neKwayedza. Zvino zvinobvira kuisa moto! Fire kuchaitika panyika bhiri, asi hapana munhu unopinza kunyange yavanaBrown. Izvi imhaka rinopisa doro huri mhinduro. Uyewo, mvura kuti zvakakangwa bepa haana nguva sasana.

mechanical balls

Crystal kukura - chimwe chezvinhu dzakakurumbira zvinhu, izvo inopa kunakidza kemisitiri. Kuedza vane crystallization kazhinji pazvinhu shuga, asi shuga crystals chinhu chitsva. Tinopa itsva uye kujairika kuona - the crystals akura mazai!

Crystal balls chingawanikwa:

• alum (inotengeswa Pharmacies);
• PVA guruu;
• Dhayi.

The crystals pamusoro mazai kukura nokukurumidza, chete pazuva. Zvakakosha kwerubwinyo rwakagara rwuripo-kugeza anoshongwa zvakasimba nokuomesa nayo. Pashure iyo mazai akazorwa guruu ndokusasa alum. Zvino vanofanira pasi kuti maawa mashoma kuti aiyanika panze zvakare.

Uyezve, dhayi ikaparara mu makapu maviri pachena mvura. Huwandu dhayi zvinogona kusarudzwa vakazvimiririra, muchiitiko ichi, chete kusimba ruvara kunoenderana crystals pauri. The mazai inoiswa dhayi zuva kana usiku. The refu zai iri mhinduro, ivo crystals kukura yakakura. Gadzirira mazai sekristaro vanofanira kunyatsoongorora - vava kusimba.

Chibharuma pamusoro bhotoro

Sezvo inogona inflated chibharuma pasina nehelium pasina kuita panyama nesimba? Kuti aite izvi, unogona kushandisa zvake kubikira pasoda uye vhiniga, izvo mumire rimwe kabati mukicheni amai ose. Kuti aite kuedza iyi kemisitiri, vanofanira:

• chibharumu;
• bhodhoro;
• 3-4 spoon ose pasoda;
• vhiniga.

Mushaba akadira zvakananga kupinda bhora achibatsirwa munhu fanera kana chipunu. Pashure pacho rakaiswa pamusoro guchu shoma vhiniga. Kamwe soda kuti bhora anotanga padzinomuka muguchu, rwunotanga kuzvimba, sokunge kuti nehelium. Izvi imhaka yokuti muvhiniga iri akaita pamwe pasoda, kusunungura carbon dioxide. Bhora ari inflated nokuda gasi mukati masekonzi mashoma chete uye kubata!

Multi-mavara akaturikidzana muguchu

Chinotevera Kuedza kemisitiri mwana ichatsanangura zvakajeka pfungwa arambe achirema nemvura. Nokuti vanoda ichi:

• mumwe kota kapu mafuta sunflower;
• mumwe kota mukombe wemvura, tinted chero inopenya ruvara;
• mumwe kota kapu shuga manyuchi (nokuti chinobudirira pfungwa, zvakakodzerawo kuwedzera dhayi).

Mwana vangafungidzira pachine chii chichaitika kana nokusanganisa ose mvura izvi. Iye akafanana mugumisiro - manyuchi unoburukira sendarama gobvu, mvura iri pakati, namafuta achagara pamusoro. Unogona kuedza mavara uye zvinwiwa, kuita sanzwisisika akafanana. Somuenzaniso, nokuwedzera uwandu shuga yakasiyana muna manyuchi, achakwanisa kuzochera mvura pamusoro densities siyana.

Laboratory kuedza muna kemisitiri inogona kunyatsonanga non-hakunakidzi. Izvi zvinoshamisa uye asi nyore mazano kubatsira anyengedzera mwana kuti kudzidza sayenzi nyore kuvaraidzwa pazuva kuchinaya.
