Poučevanje eksperimentalnega načrtovanja in omogočanje učencem, da razvijejo lastna vprašanja in hipoteze, zahteva čas. Ti materiali so bili ustvarjeni za oder in strukturo procesa, ki učiteljem omogoča, da se osredotočijo na izboljšanje ključnih zamisli v eksperimentalnem načrtovanju.
Dobro razumevanje laboratorijskih varnostnih praks je bistvenega pomena za naše študente pri izvajanju praktičnega dela v laboratoriju. Dijaki radi opravljajo praktično delo in se lahko veliko naučijo iz praktičnih dejavnosti. Izvedite več o varnosti v laboratoriju na Storyboard That!
