Dnes 17. 10. jsme nav\u0161t\u00edvili DOV. Byli jsme na programu ne\u017eiv\u00e1 voda. Nau\u010dili jsme se, \u017ee voda m\u00e1 t\u0159i skupenstv\u00ed: pevn\u00e9, plynn\u00e9, kapaln\u00e9. D\u011blali jsme pokusy: vypa\u0159en\u00ed vody, zmra\u017een\u00ed vody bez mraz\u00e1ku. P\u0159i pokusu vypa\u0159en\u00ed vody jsme dostali ochrann\u00e9 br\u00fdle, pl\u00e1\u0161\u0165 a zapalova\u010d. N\u00e1\u0161 \u00fakol byl zap\u00e1lit kahan, kter\u00fd m\u011bl oh\u0159\u00e1t vodu. Kdy\u017e nastal \u010das na pokus s mra\u017een\u00edm vody, tak n\u00e1s to bavilo. Sice se to v\u011bt\u0161in\u011b nepovedlo, ale bavilo n\u00e1s to. <\/p>\n\n\n\n

Pan\u00ed instruktorka n\u00e1m pov\u011bd\u011bla o molekl\u00e1ch vody. Molekula vody se skl\u00e1d\u00e1 z vod\u00edku a kysl\u00edku. Kapka vody m\u00e1 1 000 000 000 000 000 000 000 molekul vody. Kdy\u017e je voda pevn\u00e1 a m\u011bn\u00ed se na kapalnou, \u0159\u00edk\u00e1 se tomu t\u00e1n\u00ed. Kdy\u017e je tomu naopak \u0159\u00edk\u00e1 se tomu tuhnut\u00ed. Pokud je voda v pevn\u00e9m skupensv\u00ed a m\u011bn\u00ed se na plynn\u00e9, \u0159\u00edk\u00e1 se tomu sublimace. Pokud je tomu naopak, \u0159\u00edk\u00e1 se tomu desublimace. A jestli je voda plynn\u00e9ho skupenstv\u00ed a m\u011bn\u00ed se na kapalnou, \u0159\u00edk\u00e1 se tomu zkapaln\u011bn\u00ed. Kdy\u017e je to naopak, \u0159\u00edk\u00e1 se tomu vypa\u0159ov\u00e1n\u00ed. <\/p>\n\n\n\n

Byla to z\u00e1bava, bavili n\u00e1s experimenty a nau\u010dili jsme se hodn\u011b zaj\u00edmavost\u00ed.<\/p>\n\n\n\n
