Experiments Lesson Plans

Sigurnost Laboratorija

Oliver Smith

Čvrsto razumijevanje laboratorijskih postupaka sigurnosti ključno je za naše studente da praktični rad obavljaju u laboratoriju. Studenti vole dovršiti praktični rad i mogu mnogo naučiti iz praktičnih aktivnosti. To je učinkovit način podučavanja principa znanstvenog ispitivanja, razvijanje vještina učenika u mjerenju i promatranju te motiviranja i angažiranja učenika, ali sigurnost uvijek mora biti na prvom mjestu. Dobar je prvi korak osiguravanje da bilo koji praktični rad odgojitelj pravilno i temeljito procijeni prije nego što se aktivnost izvrši. Odgajatelji bi trebali prvo pokrenuti eksperiment ili demonstraciju prije lekcije kako bi razumjeli rizike.
