Start every physics class with a question already on the board. These warm-ups — 83 across the full year — activate prior knowledge, surface misconceptions before they harden, and buy you three quiet minutes to take attendance. Every set includes answer keys and matches our unit sequence for grades 9–12.
Which one do I need? The Warm-Ups Bundle collects all eight units in one download — the whole year of bell ringers, ready before first period. Per-unit sets work if you want to try one unit first.
