While waiting to run your unknown samples, what other task will you be doing?

The correct choice emphasizes the importance of preparation and organization in the laboratory setting. Checking all the glassware and equipment ensures that everything needed for running the unknown samples is present, clean, and in good condition. This proactive step is crucial for preventing delays or issues later in the experiment, as using dirty or broken equipment can compromise results and safety.

Additionally, this task aligns with good laboratory practices, where ensuring the adequacy of resources helps promote an efficient workflow. Having all necessary tools prepared in advance enables an orderly and focused approach once the actual experiments begin. This attention to detail is a key aspect of being a responsible and effective lab student.

Other tasks listed, such as writing a lab report or reading the lab manual, are valuable but do not directly contribute to the immediate preparation for running samples. Consulting with a peer may foster collaborative learning, but it does not address the necessity of verifying the readiness of equipment and supplies for the specific task at hand.
