Unit 02 · shared stop · 7th & 8th grade

Safety is a skill.

Before we measure, heat, mix, build, or investigate, we learn how to protect ourselves, our classmates, and the evidence. The first move is not “try it.” The first move is pause, look, and ask.

The briefing · four moves

When in doubt, make the safe move boringly obvious.

Safety is not a bravery test. It is a repeatable routine that keeps a small problem from becoming a big one.

01

Pause

Stop your hands and your feet. Do not improvise with an unfamiliar material, tool, smell, sound, or spill.

02

Protect

Use the required protective equipment and give the hazard space. Keep hair, sleeves, bags, food, and phones out of the work zone.

03

Tell

Tell the teacher or supervising adult what happened, plainly and immediately. Questions are data, not trouble.

04

Prevent

Follow the adult’s directions for cleanup, first aid, evacuation, or disposal. Never hide a mistake to protect a grade.

Watch · Khan Academy candidate

See the routine before you need it.

This is the selected middle-school candidate. It opens as a supplement; the teacher’s directions and the official contract remain the authority.

Cards · vocabulary

Know the words before the moment.

Flip the cards. The deck stays in this browser only; it does not record a grade or create an account.

Read · Eleo explains

Safety is how we make science possible.

A short companion article turns the rules into decisions you can make under pressure.

Sketch · sketchnotes

Practice the safe move on paper.

Three duplex sets turn the official English safety contract into desk-ready practice. Print the workbook, complete it, then check your thinking against the key.

What would you do next?

Choose a situation. The safe answer starts with stopping the action, creating space, and telling the supervising adult.

Practice · math + teacher assessment

Make the safe choice measurable.

Use the print sheet to practice unit conversions, averages, and reading a simple safety-check data table. Your teacher’s existing safety assessment comes after the briefing; this page stores no results.

Assessment lives with your teacher.

Complete the assigned lab-safety assessment after reviewing this page and the official contract. Ask your teacher where to submit it and what counts as passing.
