Nov yog qhov hloov pauv xim yooj yim uas zoo rau menyuam thiab cov laus. Zoo nkauj zoo nkauj hauv chav uas tsis pom kev, zoo rau hnub so, thiab ua kom pom kev tsaus ntuj zoo nkauj.

Kauj ruam 1: Cov ntaub ntawv

Rab Phom Phom - Peb tab tom siv rab phom kub kub. Nws mob thaum cov kua nplaum kov koj cov tawv nqaij tab sis nws tsis hlawv koj cov tawv nqaij 3V BatteryFilm Canister - Nrog sab hauv kaw lub hau (Fuji style) 5mm RGB LEDTwo Magnets - Ib qho yuav tsum muaj qhov nyob hauv nws thiab tsis loj dua li lub roj teeb. Lwm cov hlau nplaum yuav tsum yog me me txaus kom haum rau hauv lub hau ntawm zaj duab xis canister Txhua qhov ntawm no tuaj yeem yuav los ntawm e-bay. Peb yuav muag cov khoom siv ntawm Cat's Science Club yog tias txaus siab. Cat's Science Club

Kauj Ruam 2: Ua "Tswmciab"

Coj koj lub LED thiab khoov ntev dua (zoo) ceg ntawm 90 degree kaum. Ntxig cov ceg luv (tsis zoo) los ntawm lub qhov hlau nplaum. Khoov ceg luv thiab nce ib ncig ntawm cov hlau nplaum raws li qhia. Ntxiv lub roj teeb tsis zoo (-) sab ntsib cov hlau nplaum thiab LED. Khoov ceg ntev nyob ib ncig ntawm lub roj teeb sab nraud raws li qhia. Peb nyiam khoov ceg zoo nyob ib puag ncig kom nws tsis kov lub roj teeb. Muaj me ntsis ntawm lub caij nplooj ntoo hlav hauv xaim. Ua li no, thaum peb teeb "tswm ciab" rau ntawm lub hauv paus qhov rub ntawm cov hlau nplaum yuam kom txhais ceg kov lub roj teeb, ua rau lub teeb ci mus ntxiv. Cov kua nplaum kub ib puag ncig ntawm lub teeb ntawm LED. Tsiv lub roj teeb ib puag ncig los kho raws li xav tau. Cat's Science Club

Kauj Ruam 3: Ua Lub Hauv Paus

Nqa cov hlau nplaum thib ob thiab tshawb xyuas nws qhov polarity. Peb tsis xav kom cov hlau nplaum tawm tsam ib leeg thaum peb sim txuas lawv. Nqa cov hlau nplaum thib ob thiab muab lo rau hauv lub hau ntawm zaj duab xis. Yog tias qhov tseeb yog qhov tseeb nws yuav rub "tswm ciab" rau hauv qhov chaw. Tsis txhob tso "tswm ciab" rau lub hauv paus tseem. Kuaj polarity ua ntej gluing. Ntxiv cov kua nplaum nyob ib ncig ntawm sab saum toj ntawm cov hlau nplaum uas nyob hauv lub hau. Tsis txhob ua dhau. Ib txheej nyias nyias uas nyob sab hauv ntawm lub hau ua haujlwm zoo tshaj plaws. Cia tag nrho cov kua nplaum qhuav. Cat's Science Club

Kauj ruam 4: Tag nrho

Tam sim no nws yog lub sijhawm los muab rau nws tag nrho. Thaum cov kua nplaum qhuav tag, muab cov LED, hlau nplaum, roj teeb ("tswm ciab") tso rau hauv zaj duab xis lub raj mis hau, cov hlau nplaum (hauv paus). Kho raws li xav tau kom tau lub teeb qhib. Muab zaj duab xis tso rau saum lub teeb thiab ntsaws rau hauv qhov chaw. Yooj yim, yooj yim, thiab saib txias heev. Cat's Science Club

Kauj Ruam 5: Kev Xaiv / Tswv Yim

Hloov cov hlaws ntawm cov nplaum rau saum cov hlau nplaum hauv lub hau, ntxiv lub tshuab ntxhua khaub ncaws rau lub hau. Nws muab rau kev sib txuas zoo dua nrog roj teeb, nplaim nplaim taws teeb "tswm ciab" rau, thiab nws zoo li zoo dua. TAB SIS nws tsis tsim nyog. Lub teeb tuaj yeem tua tau yooj yim yooj yim tsuas yog los ntawm zawv zawg nws tawm me ntsis kom tsis txhob xaim hluav taws xob los ntawm kev ua tiav lub Circuit Court (kov lub roj teeb ntawm ob qho zoo thiab tsis zoo). teeb los yog khaws cia. Light tsis qhib? Sim zawv zawg lub roj teeb ib puag ncig kom kho qhov twg nws tau kov ob txhais ceg ntawm LED. Puas yog txhais ceg zoo ua rau sab zoo ntawm lub roj teeb? Puas yog lub roj teeb rov qab? Cat's Science Club
