Year 11 Queensland General Biology · Term 1 · Weeks 3–4
Educational scope and use
These materials are a bounded 350-minute conceptual teaching slice about membrane structure, transport, cell size and diffusion evidence. They follow a separate introductory cell/organelle slice. They do not complete Topic 1, Unit 1, a whole Biology course, a practical investigation or a school assessment instrument. School teachers choose sequence, access, laboratory work, safety and formal assessment. Other states and territories have their own senior pathways. There has been no classroom pilot, independent human scientific review, validated accessibility study or measured learning outcome.
All cell files, pouch values, repeat sets and numerical conditions are original supplied teaching models. They are not real biological, clinical or learner investigation records. Geometric layer fractions do not measure molecular flux or a diffusion coefficient; average Δdepth/Δtime = (d_end − d_start)/(t_end − t_start), with d_start = 0 mm and t_start = 0 min describes only the stated interval. Predictions depend on explicitly supplied permeability, gradient, temperature and pressure conditions. Charged-ion direction requires electrical information. Paper analysis and planning do not establish actual or genuine virtual investigation conduct.
The activities need paper only. No cultures, specimens, chemicals, ingestion, biological fluids, medical histories, diagnosis, treatment, hydration advice or risky home experiments are required. Any future actual practical needs a qualified teacher and the school's approved safety, disposal and access arrangements. No fabricated translation, First Nations voice or cultural material is supplied.

The QCAA CC BY licence excludes Queensland Government coat of arms and QCAA/QSA trademarks; third-party material; information expressly carrying a different excluding notice; standalone student images; student work samples; and glossary definitions. QCAA student-containing video/audio has separate CC BY-ND terms. Reproduction of information containing student images/work is subject to QCAA's rule against separating those elements from the information. None of those excluded materials, logos, artwork, student samples or media is reused in this bundle. Rights holders retain their rights. The current indexed copyright page's 2024 attribution example and 2026 footer are distinct from the syllabus-specific 2026 attribution above.
Fresh indexed readings of official pages established the relevant syllabus/version/Unit 1 scope. Ordinary QCAA requests returned 403 HTML, not a downloadable PDF. Private source witnesses keep these access failures separate from indexed readings. No downloaded raw 58-page PDF identity is claimed. The relevant unit's actual laboratory/microscopy/inquiry requirements remain beyond this paper material.
Scientific cross-checks
Scientific concepts were cross-checked against the National Human Genome Research Institute's plasma-membrane page (https://www.genome.gov/genetics-glossary/Plasma-Membrane-Cell-Membrane), bounded indexed search excerpts from Alberts and colleagues' Molecular Biology of the Cell, fourth edition (NCBI Bookshelf NBK26815 and NBK26871), and the primary-study abstract by Finean and Hutchinson, DOI 10.1016/0009-3084(88)90115-6 (https://pubmed.ncbi.nlm.nih.gov/3338100/). Full Bookshelf opens yielded browser challenges; full chapters and the full research paper were not read. These sources supplied factual checks only. No external image, exercise, passage, narration or audio is incorporated. Their source terms remain separate and no rights clearance for third-party expression is asserted.
Delivery and font rights
Give this complete notice with every delivered teaching-aid set. Give first-check pages first and collect responses before handing out later pages; staff keys remain separate. A complete text alternative must retain every source condition, number, unit, instruction and limit. Do not rely on an online or private link for this notice.
For PDF exports using embedded DejaVu, deliver its complete unchanged font notice as a separate font-rights file. Font rights do not replace the educational/source notice. No TTF distribution is required. The delivered PDFs embed DejaVu subsets. Its complete unchanged notice is supplied in FONT-LICENSE.txt and in the offline portable notice PDF. No TTF is delivered.
