Eksperimentālā dizaina mācīšana un ļaut studentiem pašiem izstrādāt savus jautājumus un hipotēzes prasa laiku. Šie materiāli ir izveidoti, lai izveidotu un strukturētu procesu, lai skolotāji varētu koncentrēties uz galveno ideju uzlabošanu eksperimentālajā dizainā.
Stingra izpratne par laboratorijas drošības praksi ir būtiska, lai mūsu studenti varētu veikt praktiskus darbus laboratorijā. Studentiem patīk pabeigt praktiskos darbus, un viņi var daudz mācīties no praktiskām aktivitātēm. Uzziniet vairāk par laboratorijas drošību vietnē Storyboard That!
