Txoj Kev 1 ntawm 3: Tsim Cov Hluav Taws Xob Hluav Taws Xob nrog Cov thom khwm thiab Ntaub Pua Tsev
Kauj Ruam 1. Muab cov thom khwm huv, qhuav
Cov hnab looj tes ntxhua khaub ncaws ntxhua khaub ncaws, ua kom lawv muaj hluav taws xob zoo dua. Cov thom khwm ntub lossis ntub tsis tuaj yeem rub tawm hauv av kom txaus kom lawv tsis muaj peev xwm tsim hluav taws xob zoo li qub.
- Cov thom khwm sov uas nyuam qhuav tau siv tshuab qhuav yog cov khoom siv hluav taws xob zoo tshaj plaws.
- Thaum cov thom khwm feem ntau tuaj yeem siv hluav taws xob zoo li qub, cov thom khwm wool feem ntau yog qhov zoo tshaj plaws.
Kauj Ruam 2. Maj mam txhuam koj txhais taw rau ntawm cov ntaub pua plag
Taug kev nrawm thaum txhuam koj txhais taw ntawm cov ntaub pua plag. Txawm li cas los xij, tsis txhob rub koj txhais taw lossis taug kev los ntawm kev tso siab ntau dhau ntawm cov ntaub pua plag. Qhov no yuav ua rau hluav taws xob raug tso tawm ntxov dhau los kom lub zog tsis muaj zog ntxiv lawm.
Cov ntaub pua plag Nylon feem ntau zoo tshaj rau kev siv hluav taws xob. Txawm li cas los xij, cov ntaub pua plag feem ntau tuaj yeem tsim hluav taws xob zoo li qub
Kauj Ruam 3. Kov lwm tus neeg lossis khoom siv hlau
Tom qab txhuam cov thom khwm ntawm cov ntaub pua plag, rub koj txhais tes thiab kov ib tus neeg lossis cov khoom hlau ze koj. Yog tias koj tuaj yeem hnov hluav taws xob los yog poob siab ntws los ntawm koj lub cev mus rau lwm yam khoom lossis tib neeg, koj tau ua tiav tsim hluav taws xob zoo li qub.
- Yog tias koj tsis xav tias muaj hluav taws xob zoo li qub, txuas ntxiv txhuam cov thom khwm ntawm cov ntaub pua plag thiab sim dua.
- Nug lwm tus neeg tso cai ua ntej koj kov nws. Nco ntsoov, tsis yog txhua tus nyiam nyiam hluav taws xob zoo li qub.
Kauj Ruam 4. Tsis txhob kov cov khoom siv hluav taws xob
Cov khoom siv hluav taws xob muaj microchips uas tuaj yeem ua haujlwm tsis zoo lossis tseem raug puas ntsoog los ntawm hluav taws xob zoo li qub. Yog li, ua ntej kov cov khoom siv hluav taws xob, hle koj lub thom khwm thiab kov lwm yam kom tso cov hluav taws xob zoo li qub.
Txawm hais tias lawv muaj txheej txheej tiv thaiv, cov khoom siv hluav taws xob tseem tuaj yeem ua rau muaj hluav taws xob zoo li qub
Txoj Kev 2 ntawm 3: Rub Cov Balloons nrog Wool
Kauj Ruam 1. Tshem lub zais pa thiab khi qhov kawg
Rub lub caj dab ntawm lub zais pa thiab tso lub qhov rau ntawm daim di ncauj. Ua pa tob tob thiab tom qab ntawd ua pa rau hauv lub zais pa kom txog thaum nws puv lawm. Tom qab ntawd, khi qhov kawg ntawm lub zais pa hauv txoj hlua kom lub dav hlau sab hauv tsis khiav tawm.
Hauv qhov kev sim no, koj yuav tsum siv lub zais pa roj hmab. Balloons hlau tsis ua hluav taws xob zoo li qub thaum txhuam nrog ntaub plaub
Kauj Ruam 2. Rub lub zais pa nrog ntaub plaub rau 5-10 feeb
Tuav lub zais pa nrog ib txhais tes thiab ntaub plaub nrog lwm tus. Nias cov ntaub plaub tiv thaiv sab saum toj ntawm lub zais pa thiab rub ob qho ua ke sib zog rau 5-10 vib nas this.
Yog tias koj tsis muaj ntaub plaub nyob hauv tsev, koj tuaj yeem txhuam lub zais pa nrog koj lub taub hau
Kauj Ruam 3. Tuav lub zais pa ze ntawm kab rov tav dej qab zib tau
Txhawm rau ntsuas hluav taws xob zoo li qub, tso cov dej qab zib tuaj yeem ua kab rov tav ntawm qhov ua kom du, tiaj. Tom qab ntawd, tso lub zais pa ze ntawm lub poom, tab sis tsis txhob cia ob leeg kov. Yog tias cov dej qab zib tuaj yeem txav deb ntawm lub zais pa, lub zais pa tau ua hluav taws xob.
Koj tseem tuaj yeem sim ntsuas hluav taws xob los ntawm kev tso lub zais pa ze koj cov plaub hau. Yog tias koj cov plaub hau nce thiab tsoo lub zais pa, koj tau ua tiav tsim hluav taws xob zoo li qub
Kauj Ruam 4. Tshem tawm cov hluav taws xob zoo li qub ntawm lub zais pa los ntawm kev txhuam nws tawm tsam cov khoom hlau
Hlau yog tus neeg xyuas pib muaj zog thiab tuaj yeem tso hluav taws xob rau ntawm lub zais pa. Ib yam li koj xav nrog ntaub plaub, tsuas yog txhuam cov hlau tawm tsam saum lub zais pa li 5-10 feeb.
Txoj Kev 3 ntawm 3: Ua Electroscope
Kauj Ruam 1. Ua 2 qhov hauv qab ntawm Styrofoam iav thiab ntxig ib lub quav los ntawm nws
Muab tus xaum xaum los yog tus pas txhuam hniav hla 2 cov ntsiab lus hauv qab ntawm Styrofoam iav. Tawm qhov nrug deb nruab nrab ntawm lub qhov thiab ntug ntawm iav. Ntxig cov yas quav hla txhua lub qhov kom ib nrab ntawm nws dai sab nraum lub qhov.
Ceev faj thaum siv cov khoom ntse xws li cov nqaij ntshiv
Kauj Ruam 2. Muab 4 lub pob zeb me me tso rau hauv lub qhov ncauj ntawm lub khob, tom qab ntawd muab lawv tso rau ntawm daim ntawv ci
Ua 4 lub pob zeb me me ntawm qhov loj me, kwv yees li 1.5 cm los ntawm txhais tes, tom qab ntawd lo lawv ntawm 4 cov ntsiab lus sib npaug hauv lub qhov ncauj ntawm iav. Tom qab ntawd, tig lub iav dua thiab muab tso rau hauv nruab nrab ntawm lub lauj kaub txhuas.
Tom qab muab lub iav tso rau hauv lub lauj kaub, cov quav yuav tsum taw ncaj
Kauj Ruam 3. Txiav ib daim xov thiab khi nws mus rau 2.5 cm daim ntawm txhuas ntawv ci
Txiav ib daim ntawm txhuas ntawv ci nrog ib sab ntev ntawm 2.5 cm. Tom qab ntawd, txiav ib txoj hlua 2-3 zaug ntawm qhov nruab nrab ntawm cov quav thiab cov ntug ntawm lub lauj kaub. Tom qab ntawd, cua cov ntawv ci ntawm ib kawg ntawm cov xov.
Kauj Ruam 4. Kaw lwm qhov kawg ntawm cov xov rau cov quav
Khi cov xov rau ob qho kawg ntawm cov hlua tawm ntawm iav thiab tom qab ntawd lo rau qhov kawg ntawm cov xov kom lawv tsis txav mus. Tom qab ntawd, kho qhov chaw ntawm cov quav nplej kom cov ntawv ci dai thiab me ntsis kov lub ntug ntawm lub lauj kaub.
Yog tias xov ntev dhau thiab tsis dai saum huab cua, txo qhov loj me raws li xav tau
Kauj Ruam 5. Kuaj lub tshuab ntsuas hluav taws xob los ntawm kev muab nws tso rau ib sab ntawm lub zais pa uas siv hluav taws xob
Ua lub zais pa uas siv hluav taws xob los ntawm rub nws tawm ntawm koj cov plaub hau lossis ib daim ntawm cov khoom plaub thiab tom qab ntawd muab tso rau ntawm lub rooj. Muab lub tshuab hluav taws xob tso rau ib sab ntawm lub zais pa. Yog tias lub zais pa tuaj yeem ua hluav taws xob, cov ntawv ci yuav tsum txav deb ntawm nws.
