A complete IB DP Physics hands-on practical for Topic A.1 Kinematics, SL and HL, first assessment 2025, offered free as a full-quality sample of the premium catalogue: students measure the acceleration of free fall, g, by timing an object falling from rest through a range of heights, then linearise s = ½gt² and read g from the gradient of an s-against-t² graph. Not a cut-down teaser but the complete practical, nothing watermarked.

This is a structured IB Inquiry lab worksheet, not an expository lesson. Students state and explain a prediction, set out the independent, dependent and controlled variables, justify the range of heights and the repeat readings, and address the safety hazards of the rig. They collect repeat fall times on an electronic millisecond timer, compute t² with propagated uncertainties, and read g from the gradient. They compare their value to the accepted 9.81 m s⁻², judge whether it lies within range, and evaluate random and systematic error.

IB skills span Tool 1: Experimental techniques, Tool 2: Technology, Tool 3: Mathematics and the Inquiry cycle:

  • Measuring time and length to an appropriate precision (taught).
  • Recording and propagating uncertainties, through a power and a gradient (taught).
  • Linearising a relationship, and drawing uncertainty bars and maximum and minimum gradient lines (taught).
  • Plotting with proper scales and axes, drawing the line of best fit, justifying a conclusion against the accepted value, and explaining realistic improvements such as light gates or video analysis (practised).

What’s included:

  • Student Worksheet - 10 pages, answers stripped
  • Teacher Key - 13 pages, every answer, model data and marking point
  • Worked Solutions - 8 pages, with the model graph
  • Assessment - 7 pages, a questions-only write-up copy with IB mark allocations
  • Lesson deck - 36 slides, staged reveals for the prediction, the processing and the graph

This is a skills practical: it does not teach a new IB understanding, but exercises the topic’s Tool and Inquiry skills against the free-fall context. Worksheet and deck open in any browser with nothing to install, and the worksheet is fully editable, so the data and heights adapt to your class. Suitable for grades 11-12 (ages 16-19).

IB DP Physics (2025) A.1 Kinematics Complete Unit Bundle

The complete Topic A.1 Kinematics unit for IB DP Physics, SL and HL, first assessment 2025, bundled into one sequenced teaching unit and priced 30% below the cost of buying the packs separately. **What's in the unit** - Nine lesson packs in teaching order: Distance and Displacement, Speed and Velocity, Acceleration and Non-Uniform Motion, Graphical Analysis of Motion, SUVAT Equations I and II, Projectile Motion I and II, and Fluid Resistance. - A1.P1, a full double-period bench practical measuring the acceleration of free fall, aim to evaluation, with honest sample data. - SL and HL topic tests with AO-tagged mark schemes, for end-of-topic assessment. - Skill packs for targeted drill on scientific notation, significant figures and unit conversion. Together the lessons cover all nine understandings of Topic A.1: position, displacement, velocity and acceleration, motion graphs, the four suvat equations, projectile motion, and the qualitative effect of fluid resistance. **Every lesson pack includes:** - An editable student worksheet - A teacher key with every answer and marking point - Worked solutions with every step and its units - A questions-only assessment with IB mark allocations - A choreographed lesson deck with staged reveals **IB skills (mostly Tool 3: Mathematics)**: identifying scalars and vectors, determining rates of change, drawing and adding vectors, converting units, selecting and rearranging the suvat equations, resolving vectors into perpendicular components, interpreting and sketching motion graphs, and linearizing data. The practical adds Tool 1 experimental technique and the Inquiry skills: measuring time and length, recording and propagating uncertainties, plotting best-fit lines, and evaluating error sources. Everything ships as self-contained HTML, so worksheet and deck open in any browser with nothing to install and the worksheet is fully editable, plus colour and black-and-white PDF of every projection and the slides. SI units, IB notation and IB command terms throughout. A1.1 is free, so you can teach a whole lesson before buying. Suitable for grades 11-12 (ages 16-19) for first teaching, assessment and revision. **Also in the catalogue, sold separately:** - [Resolving Vectors, the skill pack behind the projectile lessons](/teaching-resource/-13537892) - [Uncertainties, the arithmetic the practical leans on](/teaching-resource/-13538960) - [Uncertainties on a Graph, error bars and extreme gradient lines]( /teaching-resource/-13542412)
