Teaching Science 12 at home

Prepare before the lesson

1. Read the learning goals and inspect the figures, captions and stated conditions. Identify the idea the learner must explain, not just the terms to memorize.
2. Check the assigned reading and investigation materials. Choose the supplied-data route when equipment is unavailable, and label it honestly.
3. Work through one example yourself. Locate the checkpoint answers and decide what evidence would support an independent explanation.

Teach, discuss and check

1. Start with a prediction or an initial drawing. Ask the learner to distinguish what is observed from what is inferred.
2. Read a short teaching part together. Use the figure beside the explanation and have the learner describe its labels, arrows, axes and units.
3. Model one reasoning step, then give a changed case. Reduce support gradually and record what assistance was needed.
4. Return to the first prediction. Ask what changed, which evidence supports the revision, and what the model leaves out.

Judge the reasoning

Use these discussion criteria with the unit’s own marking guidance. They are a feedback framework, not a universal numerical grade.

• Uses the relevant scientific idea accurately.
• Selects evidence and preserves its units and conditions.
• Explains how the evidence supports a mechanism or conclusion.
• Names a reasonable limitation or a useful next test.

Keep the initial model, a corrected calculation or explanation, and one independent changed-case response. Record whether observations were collected by the learner or supplied by the course.

When the learner needs support

• If language is the obstacle, define one term with the figure before repeating the whole reading.
• If calculations are the obstacle, separate the physical relationship, substitution, units and interpretation.
• If a response copies the example, change one condition and ask for a prediction before giving more explanation.

Plan this course

Physics & Environmental Science contains 49 focused units across 11 chapters. Four explained visual parts per unit connect observations, mechanical/field/ecological models, calculations and evidence limits. This combined site course does not claim two separate school credits or AP status. Each chapter has a background reading, investigation, review and quiz, supported by a detailed parent plan and full midterm, sample and final papers.

The linked 36-week plan schedules 180 sessions: 119 unit-study sessions (two core sessions per unit plus a third for 21 demanding topics), 22 dedicated investigation sessions, 11 chapter reviews, 11 quizzes, nine exam/correction/portfolio allocations and eight consolidation sessions. Most sessions are 50–60 minutes. The complete 60-minute midterm follows its six-chapter scope in Week 19. The sample is a full 90-minute sitting in Week 35 paired with about 30 minutes of corrections; the final is one continuous 180-minute sitting in Week 36. This is a flexible authored home-study route, not validated mastery timing or school laboratory certification.

36 authored weeks are available. Keep each subject’s week number independent and adjust after checking understanding.

Materials and records

Keep dated notes, definitions, diagrams, worked problems, corrected errors, and evidence records. Record supplied versus measured data honestly. Learning progress is saved on this device; keep a separate notebook as a durable study record.

Use the course assessments

Chapter quizzes mix automatically checked questions and written responses requiring a learner/parent comparison. Use the handbook cumulative assessment and discussion rubric to judge reasoning across the course, rather than relying only on repeated fixed quizzes. Exam papers and parent keys are available from the Course exams links.
