Au folosit principii \u00eenv\u0103\u021bate la \u0219coal\u0103, au creat mici experimente \u0219i cu ele au participat la T\u00e2rgul de \u0219tiin\u021be. Sunt elevii \u0218colii Gimnaziale I.D S\u00eerbu din Petrila pe care, de la mic la mare, i-am g\u0103sit \u00een fa\u021ba unor standuri \u00een care puneau \u00een practic\u0103 diverse experimente.<\/p>\n

\"\"<\/p>\n

Pe unele le-au numit haios \u0219i a\u0219a am reg\u0103sit la Petrila Feti\u021bele Powerpuff, un echipaj NASA Junior sau \u201epiperul fricos\u201d.
\n\u201e\u00centr-o farfurie \u00een care am pus un detergent, am pres\u0103rat pu\u021bin piper \u0219i, dac\u0103 atingem cu degetul, vedem cu piperul se \u00eendep\u0103rteaz\u0103. Este un compus chimic din detergent, care face asta. Iar noi am numit acest experiment piperul fricos. Dar este pur\u0103 \u0219tiin\u021b\u0103, chiar dac\u0103 se comport\u0103 ca vampirii care fug de usturoi\u201d, mi-a explicat unul dintre copii. Al\u021bii au inventat ma\u0219ini cu telecomand\u0103, ori un adev\u0103rat barometru. \u201eAvem un giroscop, un dispozitiv \u0219i c\u00e2teva piese electronice, iar cu un mic aparat reu\u0219im s\u0103 citim presiunea atmosferic\u0103, altitudinea, temperatura, radia\u021biile UV \u0219i luminozitatea \u0219i \u00eenclinarea \u0219i acesta este un mini-satelit. Echipa noastr\u0103 se nume\u0219te Orbitron\u201d, mi-a explicat \u0219i un alt mic cercet\u0103tor.
\nAl\u021bii au demonstrat c\u0103, \u00eentr-un vas, un amestec din ap\u0103 \u0219i amidon de porumb se comport\u0103 diferit \u0219i poate fi, \u00een acela\u0219i timp lichid sau solid, demonstr\u00e2nd astfel c\u0103 intensitatea unei lovituri face diferen\u021ba.<\/p>\n

\"\"
\nTo\u021bi \u00eenva\u021b\u0103 din practic\u0103 s\u0103 explice fenomene din natur\u0103 \u0219i legi ale fizicii \u0219i chimiei, iar astfel lucreaz\u0103 \u0219i \u00een echip\u0103 \u0219i \u00eenva\u021b\u0103 s\u0103 fie competitivi.
\n\u201eDin carton, seringi ac\u021bionate cu lichid \u0219i scobitori. Am folosit tuburi \u0219i am realizat un dispozitiv cu ajutorul c\u0103ruia ridic\u0103m o doz\u0103 de suc. Totul poate fi o ma\u0219in\u0103 din viitor, ac\u021bionat\u0103 doar cu pistoane cu ap\u0103\u201d, a spus o alt\u0103 feti\u021b\u0103, \u00een timp ce un alt grup de mici cercet\u0103tori lua amprentele tuturor, ca mai apoi s\u0103 \u00eei grupeze pe categorii, pe to\u021bi cei interesa\u021bi.
\nT\u00e2rgul de \u0219tiin\u021be este cea mai bun\u0103 oportunitate, prin care copiii devin mai buni \u0219i competitivi. \u201eAvem programate activit\u0103\u021bile din S\u0103pt\u0103m\u00e2na verde, iar acest proiect a fost unul foarte a\u0219teptat de copii. La nivelul fiec\u0103rui colectiv, indiferent de v\u00e2rst\u0103, au \u00eencercat s\u0103 identifice activit\u0103\u021bi mai complexe, care s\u0103 \u00eembine, cunoa\u0219terea, spiritul de echip\u0103, colaborarea \u0219i nu \u00een cele din urm\u0103 reu\u0219ita. C\u0103 fiecare vrea s\u0103 fie cel mai bun, s\u0103 ia premiul I \u0219i s\u0103 dovedeasc\u0103 c\u0103 ceea ce \u00eenva\u021b\u0103 la clas\u0103 le este foarte util\u201d, a spus Coculeana Zoril\u0103, directoarea \u0218colii Gimnaziale \u201eI.D S\u00eerbu\u201d din Petrila.<\/p>\n

\"\"
\n\u201eEste a doua edi\u021bie \u0219i acum demonstr\u0103m c\u0103 am \u00eenv\u0103\u021bat din prima, ne-am organizat mai bine, comparativ cu anul trecut. Acum avem \u0219i sponsori, premii, iar acum a ie\u0219it o munc\u0103 de echip\u0103 cu rezultate frumoase. Vrem s\u0103 form\u0103m copiii astfel \u00eenc\u00e2t s\u0103 \u00een\u021beleag\u0103 c\u0103 trebuie s\u0103 lucreze \u00een echipe, c\u0103 fiecare este valoros \u0219i \u00ee\u0219i poate aduce contribu\u021bia\u201d, a spus \u0219i Bianca Popescu, coordonatoarea proiectului.<\/p>\n

\"\"
\nT\u00e2rgul a avut loc la Casa de Cultur\u0103 Ladislau Schmidt, iar fo\u0219ti elevi, acum liceeni, au venit aici cu echipa de robotic\u0103, tocmai pentru a le ar\u0103ta tuturor c\u0103, pornit de la mici experimente, pot ajunge la competi\u021bii de valoare, a\u0219a cum \u0219i ei au ajuns acum cu AlphaBit. \u201eNoi am fost invita\u021bi \u00een juriu. Am fost \u0219i anul trecut, deci este al doilea an \u0219i, \u00eempreun\u0103 cu elevii no\u0219tri, vom evalua proiectele celor mici \u0219i le \u0219i ar\u0103t\u0103m robotul cu care ne-am calificat la toate competi\u021biile de p\u00e2n\u0103 acum\u201d, a conchis Rolland Szedlacsek, profesorul coordonator al Echipei de robotic\u0103 a Colegiului Na\u021bional \u201eMihai Eminescu\u201d de la Petro\u0219ani.
