Speed-time graphs and acceleration

The third lesson of motion, made lesson-ready: read and sketch speed-time graphs, and define acceleration as the change in velocity per unit time. Plan, worksheet with answers, slides, and a Jigsaw activity with a full facilitation guide, built around the site simulation Acceleration from a Velocity-Time Line.

21st century skills activity

Expert cards run as a Jigsaw, with a recording sheet, answers, and a full facilitation guide so the structure runs faithfully.

The matching topic page and simulation

Send learners to the lesson online

This bundle pairs with the student topic pages Acceleration and Motion graphs, and the hook runs on the site simulation Acceleration from a Velocity-Time Line: learners shape the line to a target gradient and see that the slope is the acceleration.

How it is built

Read the slope, define the change

The simulation shows that the slope of a speed-time line is the acceleration, then the lesson reads the graph: a horizontal line is constant speed, a slope up is speeding up, a slope down is slowing down, and acceleration is a = change in velocity over time, in metres per second squared.

The Jigsaw then makes every learner the expert on one feature, who teaches it to their home group, and because the activity ships with a full facilitation guide it can be run faithfully by any teacher. The traps it pre-empts are the classic ones: confusing the two graph types, and giving the acceleration in the wrong unit. Extended learners take the gradient and the area further in the next graph lesson.
