11. Rockin Quiz! –This is your chance to rock it out in science class so don’t just sit there. At least rock your head or tap your desk etc. –After some intro slides, teacher will call on a student to rock it out on their way to the board. –Student goes to board and touches the picture that represents AC or DC on the AC/DC logo (If using a screen just point and drum the air). –Student will then pick a new student to go to the board as the teacher changes the slide.
