Practicals and parity matrix

Equipment, safety and equivalent routes for Weeks 8–13.

Local policy leads. Complete the school’s normal risk assessment. If the physical route is unsafe or inaccessible, use the offline digital, director, observation or printed route without lowering the scientific goal.

W8L1
Enzyme Action: Preparing the pH Investigation
Planning sheet, apparatus cards, pH-buffer labels, results-table template and current centre method/risk assessment supplied by the teacher. No reagent handling is required in this Introduce lesson.This lesson plans but does not authorise practical work. The teacher/technician must supply the current centre-approved Pearson method, COSHH information and local risk assessment; pupils must not infer concentrations, heating arrangements or disposal from this deck.Use the in-page planning console, then type an ordered variables table and method outline locally. It prepares the practical but does not certify completion.
Sequence printed method cards and direct an adult to scribe exact decisions. Keep all GCSE variables and safety reasoning.
A pupil-owned prediction, IV/DV/CV table, ordered method outline, results-table headings and one justified safety/control decision.
W8L2
Amylase and pH: Continuous-Sampling Investigation
Only the apparatus and prepared solutions listed in the centre's current Pearson-aligned CP 1.10 method: typically labelled amylase, starch and buffer solutions, iodine spotting tile setup, clean transfer equipment, reaction vessels, timer and authorised temperature-control equipment.Teacher/technician control applies throughout. Wear required eye protection; iodine is hazardous and stains; avoid skin/eye contact and inhalation, never taste or mouth-pipette, keep solutions labelled, follow heating and spill procedures, and use only current COSHH/local risk controls. Stop immediately if the authorised setup differs from the deck summary.If wet work is not authorised or accessible, use the included time-sequenced colour observations to practise endpoint recording. This parity route develops reasoning but does not establish that the centre-approved practical was completed.
Take a safe non-contact role—timer, interval caller, observer or exact recorder—or analyse teacher-provided raw observations. The teacher decides whether any practical evidence meets course requirements.
A dated raw table with pH, each sampled colour, first observed endpoint time, anomalies/uncertainty and the pupil's own method note. The page itself makes no CP-completion claim.
W8L3
Amylase Rate, Graph and Topic 1 Consolidation
Pupil or teacher-provided raw dataset, calculator, graph paper or local spreadsheet, ruler, command-word frame and Topic 1 retrieval grid.Analysis uses no reagents. Keep original raw data unchanged, use anonymised/class data only and follow school device/privacy rules. Do not present the analysis page as proof that the wet practical was completed.Enter the supplied local data, calculate rates with formulas, make a labelled graph and save locally. Check one value by hand so the spreadsheet does not hide an input or formula error.
Use a pre-scaled graph, rate choice cards and an adult-scribed evaluation from the pupil's exact reasoning; mathematical and command-word goals remain visible.
Shown rate working, an accurately labelled graph or equivalent data interpretation, a bounded conclusion, a strength-limitation-improvement chain and one Topic 1 transfer response.
W9L1
Cell Cycle: Copy, Check, Divide
Stage cards, chromosome-copy counters, prepared diagram or micrograph set, sequencing grid and command-word frame.This is a model-and-image lesson with no live tissue collection. If prepared slides and microscopes are used, carry microscopes with two hands, keep slides flat and report damaged glass; use only teacher-approved images.Order the same stage evidence in the local interactive and type one DESCRIBE and one EXPLAIN response. Digital completion does not replace the pupil-owned reasoning record.
Use enlarged tactile cards, spoken choices or eye-pointing while an adult records the pupil's exact sequence and reasons. The same formal vocabulary and evidence standard apply.
A complete ordered cycle, at least four stage-evidence links, a correct distinction between DNA replication and chromosome separation, and one pupil-owned explanation.
W9L2
Mitosis Sequence: Chromosome Evidence
Teacher-approved micrographs or prepared slides, microscope if authorised, stage-evidence key, tally grid, calculator and command-word frame.Use prepared material only. Carry a microscope by arm and base, begin on low power, keep slides flat and report chipped glass. No pupil tissue sampling or unapproved online image upload is required.Zoom and classify the same approved image set locally, then calculate the index and preserve uncertain classifications. Do not let automatic labels replace pupil evidence.
Use enlarged high-contrast images, tactile chromosome overlays, partner description or eye-pointing with adult scribing. The same stage evidence, calculation and uncertainty judgement remain required.
An ordered six-stage sequence, at least four observation-to-stage annotations, shown mitotic-index working and one justified limitation or improvement.
W9L3
Mitosis: Identical Daughter Cells
Chromosome counters, before/after table, calculator, fictional tissue dataset, application cards and GCSE command-word frame.Use fictional or anonymised data only.

W10L2
Stem Cells and Meristems: Potential Compared
Source-and-outcome cards, supplied fictional research table, calculator, comparison matrix and enlarged branching model.No live cells, embryos, cultures or human tissue are used. Treat medical examples sensitively, use anonymised/fictional data and do not invite disclosure or offer treatment advice.Use the local evidence matrix and calculator only. Do not search for or present unverified treatment claims; keep supplied source details attached to each conclusion.
Use tactile source icons, reduced-choice outcome cards, pre-entered calculations and exact pupil-directed scribing while retaining all three groups and the evidence limit.
A three-way comparison, correct use of self-renewal/differentiation, one shown percentage calculation and a claim explicitly limited to the supplied evidence.
W10L3
Growth and Stem-Cell Data: Evidence Before Claims
Fictional/anonymised growth chart, fictional stem-cell results table, calculator, ruler, command-word guide and claim-strength cards.Use no personal growth or medical data. This is not a diagnostic or treatment activity; use supplied fictional cases, avoid personal disclosure and route health concerns through approved school support.Use local graph/table tools and save only supplied fictional data. Check calculations by hand and do not publish, diagnose or recommend treatment from classroom outputs.
Use enlarged pre-plotted graphs, table overlays, calculator prompts, oral choice cards and exact pupil-directed scribing. Retain the calculation and evidence-limit requirements.

Visible percentage working plus a benefit-risk-uncertainty analysis that does not overclaim.
W11L3
Stem Cells: Structured DISCUSS
Simulated evidence summary, DISCUSS planner, vocabulary strip, feedback/edit pen and pencil.Pupils may use a written, spoken or exact-scribed response and may pass on sharing personal beliefs. No real treatment recommendation is made.Use the same local sentence-role lab and type locally; reload clears all entries and no response is uploaded.
Arrange sentence cards, dictate links and direct an adult to scribe. The judgement remains the pupil's.
A balanced first response, one genuine audience comment, a visible edit and the pupil's statement of what changed.
W12L1
Genetic Information: Cell to Gene
Nested hierarchy cards, chromosome/DNA ribbon model, labels, arrow strip and pencil.Desk-based. Use large pieces rather than small loose beads where choking or fine-motor access is a concern.Use the local placement lab with the same hierarchy and descriptions; it makes no network request.
