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!

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
