Cov me nyuam yeej ib txwm nyiam physics. Kev sim hauv tsev yuav pab koj paub txog cov kev cai ntawm ntuj thiab kawm ntau yam tshiab thiab nthuav. Txhawm rau ua qhov no, nws tsis yog qhov tsim nyog los tos txog qhov pib ntawm lub sijhawm kawm ntawv. Xws li lub chaw kuaj mob tuaj yeem yooj yim teeb tsa hauv tsev. Txawm tias muaj cov menyuam kawm ntawv preschool, koj tuaj yeem npaj cov kev ua si uas tsis tas yuav muaj kev txawj tshwj xeeb thiab kev cob qhia rau cov neeg laus. Txawm li cas los xij, tsis txhob hnov qab txog kev nyab xeeb ntawm cov menyuam yaus thiab coj lawv tsuas yog nyob rau hauv kev saib xyuas ntawm niam txiv. Tom qab ntawd nws yuav ua tau kom tsis txhob muaj xwm txheej txaus ntshai rau tus menyuam lub neej.

Tsim huab

Cov kev kawm theem pib hauv kindergarten yuav txaus siab rau cov menyuam yaus. Tom qab tag nrho, lawv yuav muaj peev xwm tsim tau huab tiag tiag lawv tus kheej. Ua li no, ncuav dej kub rau hauv ib lub hub peb-liter. Tom qab ntawd, koj yuav tsum muab cov dej khov rau ntawm daim ntawv ci thiab muab tso rau saum lub hub. Thaum huab cua nyob rau hauv nce, nws yuav pib txias. Cov vapor nws muaj condenses, ua rau huab. Zoo, ua li cas yog tias nws tsis los nag? Cov te uas tau sov hauv av zoo li nce siab. Nyob ntawd lawv cling rau ib leeg los ntawm qhov txias, tsim huab. Thaum lawv sib ntsib, lawvloj hlob, ua hnyav heev thiab poob. Los nag li no.

Volcano on the table

xov xwm zoo li no rau me nyuam yuav tsim los ntawm leej niam - tus dab phem nyob hauv tsev. Ua li no, koj xav tau ib tug "magic wand", manipulating uas, koj yuav tsum cam khwb cia ib tug spell, thiab lub "eruption" yuav tam sim ntawd pib. Cov lus zais ntawm qhov ua kom yuam kev no yooj yim heev. Nws yog txaus kom ntxiv dej qab zib slaked nrog vinegar rau cov dej zoo tib yam. Cia li noj ntau cov dej qab zib. Txhawm rau ua kom txhua yam zoo li muaj tseeb, koj tuaj yeem tsim lub roob hluav taws tiag tiag tawm ntawm plasticine ua ke nrog koj tus menyuam. Tom qab ntawd, koj yuav tsum tau ua ib lub qhov nyob rau hauv nws, ncuav dej qab zib muaj thiab maj mam ncuav nyob rau hauv vinegar. Tom qab ib pliag, qhov pom yuav dhau los ua qhov zoo heev: ua npuas ncauj yuav pib tawg tawm ntawm lub roob hluav taws. Yog li cov txiv neej yuav tau paub txog yuav ua li cas cov kua qaub cuam tshuam nrog alkali, thiab pom kom meej cov tshuaj tiv thaiv neutralization.

Cov kev paub txog menyuam yaus yuav tsum tau hais tawm txhua lub sijhawm. Cov menyuam yaus yuav tsum tau hais kom peb txhua tus ua pa, uas muaj ntau yam roj. Lawv nyuaj heev kom paub qhov txawv vim lawv tsis hnov tsw, thiab tsis pom lawv. Ib tug ntawm lawv yog carbon dioxide. Nws kuj yog ib feem ntawm cov dej carbonated. Koj tuaj yeem sim ua kom pom tseeb hauv tsev. Txhawm rau ua qhov no, koj xav tau ob lub raj los ntawm ib qho dej cawv, uas txawv ntawm ib leeg hauv txoj kab uas hla. Qhov nqaim yuav tsum haum nruj heev rau hauv qhov dav. Tom ntej no, koj yuav tsum tau ua ib lub qhov nyob rau hauv lub cork los ntawm ib lub raj mis yas thiab ntxig ib tug straw nyob rau hauv ob qho tib si kawg. Tom qab ntawd koj yuav tsum dilute tej jamib khob dej, thiab ncuav ib spoonful ntawm dej qab zib rau hauv lub raj mis thiab ncuav 100 g ntawm vinegar. Tom qab ntawd, sai heev koj yuav tsum tau ntxig ib lub cork nrog ib tug straw rau hauv lub raj mis, thiab qis nws lwm kawg rau hauv ib lub khob nrog diluted jam. Tus menyuam yuav tsum tau piav qhia tias vim yog kev sib cuam tshuam ntawm cov dej qab zib nrog vinegar, carbon dioxide raug tso tawm, uas nce thiab tawm hauv cov npuas. Qhov no yog ua li cas cov dej ua carbonated.

Tsab ntawv nrog tus zais

Qhov kev paub zoo li no rau cov menyuam yaus tuaj yeem ua tiav nrog kev ua si hu ua "Nrhiav cov khoom muaj nqis". Lossis koj tuaj yeem sau ib tsab xov rau qee tus txheeb ze. Muaj ob txoj hauv kev los ua ib tsab ntawv zoo li no. Txhawm rau ua qhov no, txhuam txhuam hauv cov mis nyuj thiab sau cov ntawv rau ntawm daim ntawv dawb. Nws yuav tsum tau tso cai kom qhuav. Txhawm rau nyeem nws tom qab, daim ntawv yuav tsum tuav hla lub ncu. Qhov tseem ceeb tshaj plaws yog kom tsis txhob hlawv. Koj tseem tuaj yeem ua rau nws nrog cov hlau kub. Cov kev sim yooj yim no rau cov menyuam yaus yuav nyiam cov neeg laus thiab, thiab yuav pab tau tsev neeg sib sau ua ke ntau dua. Koj tuaj yeem sau nrog kua txiv qaub lossis citric acid yaj hauv dej. Tom qab ntawd, txhawm rau daws cov lus, koj yuav tsum tau yaj ob peb tee ntawm iodine hauv dej thiab ntub cov ntawv nrog nws me ntsis.

S alt wonders

Nws yuav siv sijhawm thiab ua siab ntev los tsim kev paub ntxiv rau cov menyuam yaus. Tom qab tag nrho, koj yuav tsum loj hlob tiag tiag crystals. Txhawm rau ua qhov no, koj yuav tsum tau npaj cov kua qaub uas muaj zog heev. Nws yuav tsum yog li ntawd concentrated kom cov crystals tsis yaj lawm. Tom qab ntawd, koj yuav tsum tau txo nwshlau, thaum kawg ntawm uas yuav muaj ib lub voj me me. Tom qab ib pliag, crystals yuav pib tsim muaj. Koj tuaj yeem sim los ntawm kev xa cov xov woolen nyob rau ntawd es tsis txhob xaim. Tom qab ntawd cov crystals yuav pib loj hlob nyob rau hauv ib txoj kev sib txawv kiag li. Yog tias cov menyuam yaus nyiam qhov kev sim no tiag tiag, tom qab ntawd koj tuaj yeem ua ib qho khoom siv tes ua los ntawm cov hlau, thiab tom qab ntawd poob rau hauv cov tshuaj. Qhov kev ua ub no yuav ua rau tus menyuam ntxim nyiam, uas yuav saib xyuas qhov tshwm sim nrog kev txaus siab heev.

Lub ntsiab lus ntawm kev sim

Yog li, nws tsim nyog sau cia tias txhua qhov kev paub rau menyuam yaus tseem ceeb heev. Lawv tau nthuav tawm raws li kev ua si lossis kev lom zem, tab sis lawv yuav ua rau muaj txiaj ntsig zoo rau cov menyuam yaus. Lawv muaj peev xwm txhim kho erudition thiab ua rau kom cov menyuam nyiam kawm ntawv, uas yog ib qho tseem ceeb tshaj plaws rau kev npaj rau tsev kawm ntawv. Cov chav kawm no yuav ua tau txawm tias cov neeg uas tsis muaj kev paub tshwj xeeb hauv chemistry thiab physics. Txhawm rau ua qhov kev sim no, koj tsis tas yuav muaj cov khoom siv tshuaj tshwj xeeb, uas yog kim heev. Txhua yam koj xav tau rau zaj lus qhia no tuaj yeem nrhiav tau hauv tsev. Tsis txhob ntshai mus sim. Kev sim tuaj yeem sib txawv thiab nyuaj. Nws tag nrho yog nyob ntawm lub siab xav, kev xav thiab hnub nyoog ntawm tus menyuam nws tus kheej. Tab sis tsis txhob hnov qab: cov menyuam yaus yuav tsum nkag siab tias lawv ua dab tsi. Yog li ntawd, txhua qhov kev ua yuav tsum tau hais tawm thiab cov txheej txheem txuas ntxiv tau piav qhia.
