Every part, two ways
Each part of the bundle opens right here on the site, projectable in any browser, and downloads as an editable file, never a locked PDF. Adapt them to your set, your timing and your school's calendar.
Lesson plan
The 45-minute plan, with the simulation hook, the idea of g, examiner traps and a timing and contingency note.
Worksheet and answers
Six original questions with a full worked answer key and marking notes.
Slides
Your actual slides, presented right in the browser, with the live simulation linked beneath; the download is fully editable.
21st century skills activity
Question rounds run as Numbered Heads Together, with answers and a full facilitation guide so the structure runs faithfully.
Send learners to the lesson online
This bundle pairs with the student topic page Free fall, and the hook runs on the site simulation The Hammer and The Feather: drop both with air resistance on and off and watch what changes.
One idea, made unforgettable
The simulation shows the whole idea in one drop: with the air removed, a hammer and a feather land together, because the acceleration of free fall g is the same for every mass. The lesson then fixes the speed-time picture, a straight line of gradient g, and the relationship v = g t.
Numbered Heads Together then rehearses the precise statements and a calculation, and because nobody knows who will be called, every learner prepares. The activity ships with a full facilitation guide so it can be run faithfully by any teacher, and the traps it pre-empts are the classic ones: heavier objects falling faster, and confusing g with a speed or a weight.
