You can go to the website of the Physics Experiment Center and send a short message to both teachers, saying that you have staggered the experimental reports, or it may be better to contact the teachers themselves, because the teachers don't know when they will go to the website of the Physics Experiment Center. . . . . . Or go to the teacher in person, but I am thinking that all the teachers' preview reports are signed. When correcting the experiment report, the teacher should find Bush's own signature or the experiment that he is not responsible for, and give it to another teacher.
