A free IB DP Physics skill pack on scientific notation, SI prefixes, order of magnitude and estimation (SL and HL, first assessment 2025): a rules reference, four worked examples and more than 60 graded practice questions, all answered. Not a cut-down teaser but the whole pack, nothing watermarked and no answer withheld, so you can see what the paid packs deliver before you buy.

These are techniques the syllabus assumes but no topic owns. The IB asks for them to be practised inside the topics that need them, so this is not a taught unit: it is reference and remedial material that supplements integrated teaching, for the first fortnight or for a student losing marks on notation rather than physics.

This pack is worked, not taught: the teaching duration shown is student working time across the practice bank, about 140 minutes, not classroom delivery time.

What students learn:

  • Writing a value as a x 10^n, including one that already carries a power of ten (128.32 x 10^-5 is 1.2832 x 10^-3)
  • Choosing a prefix by rule, not by eye: 4.5 x 10^-7 m is 450 nm, and prefixes come off before a value enters a formula
  • Reading an order of magnitude off the index, and working a ratio out rather than subtracting indices
  • Estimating from reasoned values, stating every assumption, and quoting the order of magnitude the working supports
  • Replacing a non-SI unit by its definition: 90 km h⁻¹ becomes 25 m s⁻¹ by two separate moves, not one

Three tiers: A, 38 fluency items in seven sets, ending with an inverted set; B, 11 applied items including two estimates; C, four multiple-choice items with every distractor explained, and two structured questions worth 21 marks.

IB skills (Tool 3: Mathematics): the pack teaches scientific notation, SI prefixes and units, order of magnitude, and approximation and estimation; it practises non-SI units of time and basic arithmetic and algebra.

What’s included:

  • Student Worksheet (17 pages), answers stripped out rather than hidden, colour and printer-friendly B&W
  • Teacher Key (25 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).

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)
