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 Predict-Observe-Explain plan, with the force story, the simulation, examiner traps and a timing and contingency note.
Worksheet and answers
Six original Extended 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
An Anticipation / Reaction Guide run as Predict-Observe-Explain: a statement sheet with answers and reasons, a parachute extension, and a full facilitation guide so it runs faithfully.

This bundle pairs with the student topic pages Terminal velocity and Free fall, and the lesson runs on the site simulation The Skydiver Force Balance, where the weight and air-resistance arrows change as the speed-time line flattens.
Predict, observe, explain
Learners commit to six agree-or-disagree statements about a falling skydiver before any teaching, then watch the simulation, then return to the same statements with a force reason for each. The simulation makes the two forces visible: the weight stays the same while the air resistance grows with speed, until the two are equal and the speed-time line goes flat.
The reaction round is where the physics is fixed, and the traps it pre-empts are the classic ones: that balanced forces mean stopped, that air resistance is constant, and that a parachute brings the skydiver to a halt rather than to a new lower terminal velocity. The activity ships with a full facilitation guide so the cycle can be run faithfully, including by a cover teacher.
