20 questions
Question 1: Is it permissible to pressure students into participating in an experiment, such as one investigating reaction time, if it is for a class activity?
A. Yes
B. No
Explanation: Students should not be forced to participate against their will or feel pressured to take part in experiments involving them.
Question 2: It is acceptable to directly touch chemicals, such as a hazardous liquid, if you are wearing gloves to protect your skin from contact.
A. Yes
B. No
Explanation: The study materials explicitly state: 'Never directly touch any chemicals (even if you're wearing gloves).'
Question 3: When working with electronics, using a low enough voltage and current helps prevent wires from overheating.
A. Yes
B. No
Explanation: To prevent wires from overheating and potentially melting, and to avoid damaging components like blowing a filament bulb, it is essential to use a low enough voltage and current when working with electronics.
Question 4: After using an immersion heater to heat liquids, it is recommended to immediately wipe it dry with a cloth before storage to prevent any liquid from leaking inside the heater.
A. Yes
B. No
Explanation: When using an immersion heater, you should always let it dry out in air after use, just in case any liquid has leaked inside the heater, rather than wiping it dry immediately.
Question 5: When using a laser, it is a required safety rule to always wear laser safety goggles.
A. Yes
B. No
Explanation: The study materials state: "If you're using a laser, there are a few safety rules you must follow. Always wear laser safety goggles..."
