Physics Bell Ringers Unit 3 - 45 Daily Warm-Ups (Grades 9-12)

Start every class with a focused five-minute warm-up. This is Unit 3 of the Physics Bell-Ringers full-year set: 45 daily prompts covering Work, Energy, Power & Thermodynamics.

WHAT'S INSIDE

- 45 daily bell-ringers (Weeks 19-27), organized as nine ready-to-print weekly pages

- One page per week: five prompts, Monday through Friday, with answer space

- A complete answer key for every prompt

- A standards page listing the NGSS and CCSS literacy codes and content covered

TOPICS

- Work, kinetic energy, gravitational and elastic potential energy, conservation of energy, power, simple machines and mechanical advantage, temperature and heat and thermal energy, heat transfer and specific heat and phase change, and the gas laws and the laws of thermodynamics.

WEEKLY ROUTINE

- Monday vocabulary, Tuesday a short reading, Wednesday an analysis question, Thursday a quick check, Friday a claim-and-evidence question

- About five minutes a day; hand out Monday, collect Friday

FORMAT

- Print-first PDF, US Letter, low-ink, two-sided friendly - no logins or apps required

- Reading passages are original writing - no copyrighted text to clear, and no textbook required

- Every calculation resolves to a clean value, so a Wednesday prompt stays a five-minute warm-up rather than turning into a problem set

- Grades 9-12; works as a daily opener, an exit slip, spiral review, or emergency sub work

ALSO WORKS WITH

- Teaching Chemistry too? The Chemistry Bell-Ringers set is the other half of the high school science shelf and runs the same weekly routine.

- Teaching Grades 6-8 as well? The Physical Science Bell-Ringers set covers forces, energy and waves at the middle-school level and is the on-ramp to this one.
