1. what is the most important safety rule to remember during lab activities?

wear gloves, goggles, and protective clothing.
thoroughly wash your hands after every scientific activity.
follow your teachers instructions and the textbook directions exactly.
read the entire procedure before beginning your experiment.

Explanation:

Following teacher's instructions and textbook directions exactly is crucial. Teachers have lab - safety knowledge and experience. Textbook directions are standardized. Ignoring them can lead to accidents like chemical spills or incorrect equipment use. Wearing gear (first option) is part of safety but depends on instructions. Washing hands (second option) is post - activity. Reading the procedure (fourth option) is good but following instructions precisely (third option) encompasses it and ensures overall safety.

Answer:

Follow your teacher’s instructions and the textbook directions exactly.
