Which items are required to bring every week to the lab and TA office hours?

• A. Safety sheets, pants, proper shoes
• B. Lab manual, notebook, safety goggles
• C. Calculator, ruler, safety gloves
• D. Water bottle, snacks, headphones

Answer: (A)

The main idea here is safety basics in the lab and having quick access to hazard information. Bringing safety sheets (the hazard information) and wearing protective clothing like pants and closed-toe shoes ensures you’re prepared to handle any chemical or spill hazards and protect your skin and feet during weekly lab activities or while meeting with the TA.

Other items are less universally required. A lab manual or notebook is helpful for recording work, but not necessarily required every week for office hours. A calculator, ruler, or gloves might be handy for specific tasks, but they aren’t guaranteed essentials for weekly attendance. Water, snacks, and headphones are not appropriate for safety and focus in the lab environment.
