Choose, Test & Improve a Thermal Protector

Library package prepared 2 November 2026. Revised guides are marked with that date; unchanged teacher and student/core editions retain their file labels. Use the matching current guide supplied beside each task.

Keep this package with the teacher. Choose one stage at a time. Distribute only its student files and required sources. Teacher keys and reserved independent/follow-up/later tasks have separate folders. A teaching model may intentionally contain an answer; keep checks for later use aside during teaching.

PDF and available native editable files are included. Open the linked preparation page for accessible browser versions, current printing directions and any additional equipment. Online links need an internet connection. Timings are planning estimates; these materials do not establish classroom effectiveness or test equivalence.

Choose, Test & Improve a Thermal Protector

Compare every design criterion, justify a choice, propose a redesign, and use new evidence to reassess it.

Prerequisites: Read table headings, °C, starts and changes; compare fresh trials and conditions; distinguish observed results from explanations. The included prerequisite mini-lesson teaches criteria, constraints, prediction/result and whole-design versus feature claims.

Prepare: Read the supplied teacher quick start; preparation time depends on the selected route. Timing: Plan the selected lesson with the teacher guide
