The lesson plan for Does Water Always Boil at 100°C? Here’s What You Should Know helps parents and carers explore this fascinating scientific question with their children. While we often learn that water boils at 100°C, this lesson explains why that’s not always true. Using simple, clear language, the plan covers how altitude, air pressure, and added substances like salt affect the boiling point of water.

It provides a flexible structure with activities, discussion questions, creative tasks, and deeper thinking prompts. The tasks are designed to suit a wide range of ages and abilities, and the plan can be used as a one-off lesson or part of a wider science project on states of matter, weather, or kitchen chemistry.

Whether your learner prefers hands-on experiments, reading, or drawing, you’ll find something in this lesson to spark their curiosity. Parents don’t need any science background—just follow the plan and learn together! It’s ideal for Elective Home Education families who want a ready-to-use lesson that still leaves room for personalisation and creativity.
