Za podučavanje eksperimentalnog dizajna i dopuštanje učenicima da sami razviju pitanja i hipoteze potrebno je vrijeme. Ovi materijali su stvoreni da osnuju i strukturiraju proces kako bi omogućili nastavnicima da se usredotoče na poboljšanje ključnih ideja u eksperimentalnom dizajnu.
Čvrsto razumijevanje sigurnosnih praksi u laboratoriju ključno je za naše studente za obavljanje praktičnog rada u laboratoriju. Učenici vole obavljati praktični rad i mogu puno naučiti iz praktičnih aktivnosti. Saznajte više o sigurnosti u laboratoriju na Storyboard That!

Risk Management
Seeing how fast you can run 100 m
• Students could fall and hurt themselves • Asthma attack if students have asthma • Strained muscles
• Clear the running track of objects that people could fall over • If the participant has asthma check that they have their inhaler • Warm up and cool down effectively
Heating
Heating with a Bunsen burner
• Students could burn themselves • Students could set their hair alight • Students could damaged their eyes
• Leave the equipment to cool before touching it • Switch their Bunsen burner off when they finish heating • Wear safety googles when heating and tie hair back
Dissection
Dissecting a sheep's heart with scissors and scalpel
• Students could cut themselves while using scalpel or scissors • Students could get food poisoning from contaminated hearts
• Don't walk around with scalpel or scissors • Wear gloves during dissection and wash hands after dissection • Disinfect desks and materials after the dissection
