I encourage teachers order at least 1 day in advance. So I have time to prepare and assist better. For example, some chemicals doesn’t dissolve fast. Limewater needs to be shaken every few hours for a period of 24 hours to ensure that as much calcium hydroxide dissolves as possible. And I encourage teachers keep basic equipment in their classrooms, such as glass rod, test tube. And teachers take care of them. It’s better if students can wash them and put them back in the cabinets, since we don’t have a Laboratory glassware washer. If there is one or two difficult to be washed, no problem, the teacher can give it to me, I can soak it and find a solution.
