⒊ Don't talk loudly.
⒋ Don't run or play here.
⒌ Don't disturb (打扰) others when they do experiments.
⒍ Don't take things into the lab to do experiments until the teacher agrees.
⒎ Follow the teachers' instructions (指令) to do experiments.

⒐ Don't touch (碰) anything until the teacher asks you to do so.
⒑ Need to put all the things back after you finish the experiments.
