KH-SCI-IIS9 · Units 00–12 · Public Practice & Portfolio Preparation
Comprehensive Final Practice Assessment
Scientific habits, inquiry, life science, ecology, chemistry, physics, Earth systems, astronomy, information, and sustainable engineering.
Final examination instructions
Complete the exam independently
Use only the materials, calculator, formula sheet, or accommodations authorized by the instructor.
Answer every objective question
Each attempt contains 104 objective questions—8 per Unit 00–12—drawn from a larger persisted question bank.
Complete all written responses
Six public practice responses may be educator-scored separately for formative feedback; they are not the protected official final prompts.
Review before submission
Use the unit selector and numbered navigator to revisit unanswered or uncertain questions.
Progress saves in this browser
Responses remain available on this device until the exam is submitted, reset, or browser data is cleared.
Document the final record
After submission, review the results, complete corrections as required, and export or print the examination record.
Practice mastery targets
Public practice target: 84/104 objective and a recommended 6/8 diagnostic per unit. Six practice responses may be reviewed for a formative 200-point portfolio estimate. Official final mastery remains separately supervised and authenticated. Corrections and randomized retakes are encouraged.
Comprehensive objective practice
Complete the generated 104-question practice form
Work methodically across every science domain. Monitor your answered-question count, move between units as needed, and submit only after reviewing the complete examination.
Final examination results
Review your comprehensive performance
Use the unit and domain breakdown, correction review, and written-response record to determine practice readiness and any required remediation. Official course mastery remains separately supervised and authenticated.

Six integrated practice responses complete the 200-point formative portfolio
Each public practice response may be educator-scored from 0–16 for formative feedback. Official final scoring remains separately supervised and protected.
Units 00–01
Scientific Inquiry, Safety & Evidence
Design a safe investigation of how one controllable factor affects the cooling rate of water. Define the independent, dependent, and at least four controlled variables; write an operational definition; specify equipment resolution, repeated trials, a data table, graph choice, and analysis method; explain how you would handle anomalies and uncertainty; and identify safety, consent, privacy, and environmental boundaries. Conclude with an example claim, evidence statement, and scientific reasoning statement.
Units 02–04
Cells, Homeostasis & Inheritance
A multicellular organism experiences dehydration and must maintain cell function. Explain how membrane transport, surface-area-to-volume ratio, specialized cells, circulatory transport, kidney function, nervous/endocrine coordination, and negative feedback contribute to homeostasis. Then explain how mitosis supports repair, how meiosis and fertilization create variation, and why genotype does not determine phenotype with certainty. Include one calculation or quantitative model and two ethical limits on biological or genetic data.
Units 05–07
Ecosystems, Atoms & Chemical Change
A wetland receives nutrient-rich runoff and a proposed treatment material is evaluated. Construct a food-web and matter-cycle explanation for possible ecological effects; distinguish observation from evolutionary or historical inference; calculate one biodiversity or population measure; use atomic structure and periodic patterns to explain the treatment material; write and balance one relevant reaction; analyze conservation, energy transfer, reaction rate, and equilibrium; and evaluate safety, community, biodiversity, and source-quality tradeoffs.
Units 08–09
Motion, Energy, Circuits, Waves & Information
Design a low-voltage sensor system mounted on a 4.0 kg cart. The cart changes velocity from 1.0 m/s to 5.0 m/s in 2.0 s; calculate acceleration, net force, initial and final kinetic energy, and momentum change. The sensor uses 6.0 V across 12 Ω for 30 s; calculate current, power, charge, and energy. A 150 Hz signal travels at 300 m/s; calculate wavelength and period. Explain induction or motor action, analog-to-digital conversion, noise and error checking, and identify system boundaries, model limits, and safety requirements.
Units 10–11
Earth, Climate, Space & Cosmic Evidence
An Earth-observation satellite studies watershed change and climate. A watershed receives 120 mm precipitation, 50 mm evapotranspiration, and 45 mm runoff over 2.0 km²; calculate storage change and runoff volume. An energy model uses 340 W/m² incoming solar energy, albedo 0.30, and 236 W/m² outgoing energy; calculate reflected, absorbed, and net imbalance. A signal travels 1.50×10¹¹ m; calculate light time. A spectral line shifts from 500.0 to 500.5 nm; calculate redshift and the small-shift speed approximation. Connect plate processes, biogeochemical cycles, greenhouse forcing, orbital motion, spectra, and remote sensing while distinguishing observation, calculation, model, projection, and inference.
Unit 12 and full-course integration
Sustainable Engineering Capstone Synthesis
Select a safe community sustainability challenge. Define stakeholders, need, baseline, system boundary, measurable criteria, hard constraints, and evidence sources. Generate at least three concepts and explain a weighted decision matrix with sensitivity analysis. Propose a model or low-risk prototype, repeated test plan, uncertainty analysis, and optimization strategy. Include life-cycle, circularity, risk, reliability, resilience, accessibility, privacy, cultural, labour, environmental-justice, monitoring, maintenance, and end-of-life considerations. Show how at least four scientific disciplines from the course inform the final recommendation.
