lab coat Petri dish Bunsen burner loose-fitting clothing
I gave my students this multiple choice question: A student is conducting an investigation using chemicals. Other than goggles and gloves, what else should the student use in order to conduct this investigation safely?

Only one answer is correct among these 4 choices:
- lab coat
- Petri dish
- Bunsen burner
- loose-fitting clothing

Could you tell me which one is correct?
