Å undervise i eksperimentell design og la elevene utvikle sine egne spørsmål og hypoteser tar tid. Disse materialene er laget for å stillas og strukturere prosessen slik at lærere kan fokusere på å forbedre nøkkelideene i eksperimentell design.
En solid forståelse av laboratoriesikkerhetspraksis er avgjørende for at studentene våre skal kunne utføre praktisk arbeid i laboratoriet. Studentene elsker å fullføre praktisk arbeid og kan lære mye av praktiske aktiviteter. Lær mer om laboratoriesikkerhet på Storyboard That!
