Ntau cov khib nyiab muaj cov qauv siv lead ua, thiab cov kev daws teeb meem sib txawv tuaj yeem tsim ntau qhov ntau thiab tsawg thiab cov duab ntawm cov muaju. Ob txoj kev crystals tuaj yeem tsim yog los ntawm nag lossis daus.

Ntxhais

Ntxhais dej tshwm sim thaum cov tshuaj tau ua kom sov, thiab cov kua dej ntau dua yog yaj dua li cov kuab tshuaj ib txwm tuav ntawm chav tsev kub. Qhov no tsim cov tshuaj supersaturated. Ib qho ntxiv solute uas tau ntxiv yuav ua rau ntau dhau "poob" tawm ntawm cov tshuaj thiab tsim ib qho crystal precipitate. Cov txheej txheem no haum rau txhua lub hnub nyoog, tab sis cov me nyuam yau yuav xav tau ib tug neeg laus ua cov cua sov tshaj qhov cub.

Materials

  • Pan
  • cub lossis phaj kub
  • Ob khob dej
  • Phau mus rau rau khob granulated qab zib
  • Food coloring
  • diav loj
  • Cov kaus poom loj loj
  • String
  • Cwj mem
  • Tape
  • paper clip
  • Plastic qhwv

  1. qhwv txoj hlua ib ncig ntawm tus cwj mem ob peb zaug thiab tuav nws nrog ib daim kab xev.
  2. Muab cov xaum hla lub qhov ncauj ntawm lub hub thiab txiav txoj hlua kom nws nyob li ib nti ntawm hauv qab ntawm lub hub.
  3. Kaw daim ntawv clip mus rau qhov kawg ntawm txoj hlua.
  4. Nqa ob khob dej rau hauv lub lauj kaub rau ntawm qhov cub.
  5. Ntxiv li ib feem peb khob suab thaj ib zaug, do hauv qab zib kom txog thaum nws yaj. (Ceeb toom: nws yuav nyuaj rau do hauv cov suab thaj raws li cov tshuaj ze rau saturation. Cia nplawm kom txog thaum koj tsis tuaj yeem yaj ntxiv.)
  6. Tshem lub lauj kaub los ntawm tshav kub thiab ntxiv cov zaub mov xim (xim tsaus ua haujlwm zoo dua).
  7. Cia cov tshuaj txias li tsib feeb.
  8. Ua tib zoo muab txoj hlua khi rau hauv cov tshuaj thiab tom qab ntawd yob hauv cov suab thaj qhuav qhuav.
  9. Phos cov tshuaj rau hauv lub hub thiab hloov cov cwj mem hla lub qhov ncauj nrog txoj hlua submerged rau hauv lub hub.
  10. Npog lub thawv nrog yas qhwv thiab muab tso rau qhov txias.

Crystals yuav tsum pib tsim ntawm txoj hlua hauv ob peb teev, tab sis lawv yuav siv sijhawm li 10 hnub kom tiav daim ntawv.

Evaporation

Crystal tsim los ntawm evaporation yuav tsim muaju loj nyob rau hauv ib lub sij hawm ncua li ntawm ib lub lim tiam. Hloov cov crystals ntog tawm ntawm cov tshuaj, cov kua ib feem ntawm cov tshuaj yuav evaporate tawm hauv qab cov khoom muaju. Cov kua nplaum sib txawv yuav tsim cov duab sib txawv. Cov txheej txheem no ua haujlwm rau txhua lub hnub nyoog.

Materials

  • Tsib tablespoons Epsom ntsev
  • Tsib tablespoons zaub ntsev
  • 11 tablespoons dej kub
  • Red zaub mov coloring
  • Blue zaub mov coloring
  • Ob lub khob yas
  • ob diav
  • Ob lub hub me nyuam noj (los yog lwm lub khob me me)

txheej txheem

  1. Muab tsib tablespoons Epsom ntsev rau hauv ib lub khob yas.
  2. Ntxiv tsib tablespoons dej kub thiab do kom txog thaum ntsev yaj.
  3. Ntxiv peb mus rau plaub tee ntawm cov zaub mov xiav xim thiab muab tso tseg.
  4. Muab tsib tablespoons ntsev rau hauv lwm lub khob yas.
  5. Ntxiv rau 6 tablespoons dej kub thiab do kom txog thaum nws yaj.
  6. Ntxiv peb mus rau plaub tee ntawm cov zaub mov xim liab.
  7. Pob ib tablespoon ntawm Epsom ntsev tov rau hauv ib lub hub khoom me nyuam.
  8. Pob ib tablespoon ntawm cov lus ntsev tov rau hauv lwm lub hub khoom me nyuam.
  9. Muab cov hub tso tseg thiab cia cov kua evaporate li ib asthiv.

Cov muaju yuav tsum pom nyob rau hauv ob peb hnub, tab sis nws yuav siv li ob lub lis piam ua ntej cov kua tau evaporated.

Ntau Crystal Experiments

Yog tias koj tab tom nrhiav kev lom zem ntau dua los tsim cov muaju, muaj ntau yam kev sim hauv online. Cov txheej txheem hauv qab no siv cov ntaub ntawv sib txawv thiab ua rau qee qhov kev tshawb fawb zoo nkauj.

  • Borax, tshuaj ntxuav, ua kom muaj kuab lom zem. Cov txheej txheem tshwj xeeb no yuav ua rau cov muaju uas ua rau cov duab snowflake.
  • Alum ua kom loj, ib qho muaju. Koj tuaj yeem pom alum hauv cov txuj lom ntawm cov khw muag khoom noj. Nrog kev ua siab ntev me ntsis, ib leeg, loj, ntshiab crystal yuav tsim los ntawm daim ntawv qhia no.
  • Aragonite crystals yuav loj tuaj rau saum pob zeb nrog ib co dawb vinegar.

Kev zoo nkauj ntawm Crystals

Crystals ua rau kev tshawb fawb los ua neej. Nrog kev ua siab ntev me ntsis thiab cov txheej txheem tsim nyog, koj tuaj yeem tsim cov pob zeb zoo nkauj ntawm cov duab sib txawv thiab ntau thiab tsawg.
