An IB DP Physics skill pack on unit conversion (SL and HL, first assessment 2025): a rules reference, six worked examples and 62 graded practice items, every one answered. SI prefixes, compound units such as g/cm3, squared and cubed units. Free, and the whole pack.

Unit conversion is a technique the syllabus assumes but no topic owns, and the IB asks for it to be practised inside the topics that need it. This is not a taught unit: it supplements integrated teaching as reference and remedial material for a student losing marks on units, not physics.

This pack is worked, not taught: the teaching duration shown is student working time across the practice bank, about 160 minutes, not classroom delivery time. It divides into three sittings of about 55, 65 and 40 minutes.

What students learn:

  • Building a conversion factor equal to 1 and putting the unwanted unit where it cancels, so the surviving units check the working
  • Routing between two prefixes through the unprefixed unit, off a card of 14 metric multipliers
  • Time in both directions, plus the litre, kilowatt hour, light year and electronvolt
  • One factor per unit in a compound (95 km h⁻¹ is 26 m s⁻¹ by two moves, the origin of dividing by 3.6), and the whole factor raised to the power a squared or cubed unit carries: 1 m2 = 10^4 cm2

Three tiers: A, 41 fluency items in seven sets; B, 14 applied items where nothing signals a conversion; C, four multiple-choice items, every distractor explained, and three structured questions worth 26 marks.

IB skills (Tool 3: Mathematics): the pack teaches applying and using SI prefixes and units; students practise non-SI units, basic arithmetic and algebra, scientific notation, and areas and volumes for simple shapes.

What’s included:

  • Student Worksheet (18 pages), answers stripped out, colour and printer-friendly B&W
  • Teacher Key (28 pages), every answer and model solution, plus teaching notes
  • The editable worksheet, a self-contained HTML file

The worksheet and the key are two projections of one source, so no answer file can drift. Grades 11-12 (ages 16-19).

Part of the A.1 Kinematics Complete Unit Bundle: every pack for the topic, 30% off buying them separately.

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)
