Japhia Huhndorf is accused of helping students get high on chloroform and having explosives in her Livingston High School classroom.
She appeared in court Friday over a video screen from jail. The defense attorney asked to postpone entering a plea, and the judge agreed. Outside the courtroom, Huhndorf's sister and other supporters who did not identify themselves spoke out on her behalf.
Attorneys for both sides did not want to comment. Huhndorf is scheduled to appear in court again on Wednesday. Her bail remains at a half million dollars.
