Question 16

When you don't understand experiment instructions, the best practice is to ask the teacher for clarification to ensure safety and accuracy. Guessing, copying, or skipping can lead to mistakes or safety issues.

In a science lab, directly smelling chemicals is unsafe as many chemicals are toxic, corrosive, or irritating. Proper identification methods (like using labels, MSDS) should be used.

Working with a laptop near a sink in a science lab is unsafe because water from the sink can spill onto the laptop, causing damage or electrical hazards.

Answer:

A. Ask the teacher for clarification.
