KH-SCI-IIS9 · After Unit 07 · Transition Benchmark
Practice Midterm · Units 00–06 Cumulative Chapter Test
Cumulative midterm practice across readiness, inquiry, cell biology, homeostasis, inheritance, ecology, and atomic structure. Public practice supports preparation; official midterm mastery remains separately supervised and authenticated.
Before you begin
Work independently
Use only the resources your instructor has approved.
Complete every question
Unanswered objective questions count as incorrect.
Progress saves locally
Your responses remain in this browser until submitted or cleared.
Review before submitting
Use the numbered navigator to revisit incomplete questions.
Evidence and belief-neutral assessment
Unit 05 questions distinguish observation, measurement, scientific inference, methodological naturalism, and worldview interpretation. Personal belief is not scored. Accuracy, evidence classification, reasoning, source fairness, and respect are scored.
Objective assessment
Complete all 70 questions
Work carefully through Midterm · Units 00–06, monitor your answered-question count, and submit only after reviewing the complete test.
Assessment results
Review your performance
Use the unit breakdown and question review to identify strengths, corrections, and the next steps required for mastery.
Objective Result
Constructed section
Three responses complete the 100-point formative practice estimate
Each response is scored from 0–10 using the educator rubric.
Practical / Data Analysis
Inquiry, Measurement, and Uncertainty
A student measures cooling water at 0, 2, 4, 6, and 8 minutes and records 80.0, 71.8, 65.1, 59.5, and 55.0 °C. Identify the independent and dependent variables, calculate the average temperature change per minute from 0 to 8 minutes, choose an appropriate graph, distinguish a direct observation from a causal inference, identify one uncertainty source, and propose one method revision. State what evidence would be required before claiming one factor caused the cooling pattern.
Life Science Integration
Cells, Homeostasis, Inheritance, and Ecosystems
Explain how cell structure supports one transport or energy function, then connect that function to organism-level homeostasis. For a simple inherited trait scenario, distinguish genotype from phenotype and explain why a Punnett square predicts probabilities rather than guarantees. Finally, connect inherited variation to one population or ecosystem question and identify which evidence would be observational versus experimental.
Physical Science / Model Defense
Atomic Evidence and Model Revision
For ²⁴Mg²⁺, determine protons, neutrons, and electrons. Explain how scattering evidence changed the atomic model, how isotope evidence relates to weighted atomic mass, and how a line spectrum supports discrete energy differences. Include one limitation of a simplified shell model and one example of how scientific models improve when new evidence conflicts with an older explanation.
