• All of the above

What should you do if a piece of lab equipment starts malfunctioning during an experiment?

• Continue using it

• Try to fix it yourself

• Inform your classmates

• Turn it off and inform the science instructor

After handling lab equipment and substances, you should always

• apply hand sanitizer

• rinse your hands with water only

• wash your hands thoroughly with soap and water

• wipe your hands on a lab coat

Imagine you're a scientist and a fire suddenly breaks out in your lab. What's your first move?

• Finish your mission and see a doctor after school

• Immediately inform your science instructor about the incident

• Use your secret agent skills to apply first aid yourself

Imagine you're in a science lab, and your friend suggests some horseplay or practical jokes. What's your response?

• "No way, that's always against the rules!"

• "Sure, why not?"
