Science 10 Session 06
Alberta Grade 10 Science course-first tutoring portal aligned to the Biology 30 delivery model.
Session 06: Cells, Transport and Matter Cycling
Unit focus: SCI10-C · KCO targets: SCI10-C-KCO-01, SCI10-C-KCO-02
Lesson material block: MB-OCP-SCI10-06
1. Essential knowledge definitions
| Term | Definition |
|---|---|
| cell | The basic unit of living things. |
| cell membrane | The boundary that controls what enters and leaves a cell. |
| diffusion | Movement of particles from high to low concentration; no energy needed. |
| osmosis | Diffusion of water across a membrane from high to low water concentration. |
2. Vocabulary / symbols
- cell: The basic unit of living things
- cell membrane: The boundary that controls what enters and leaves a cell
- diffusion: Movement of particles from high to low concentration; no energy needed
- osmosis: Diffusion of water across a membrane from high to low water concentration
3. Prerequisite ladder
- Cell readiness: cell → cell membrane → diffusion → osmosis
- Energy-process readiness: photosynthesis → glucose → oxygen → cellular respiration
4. Mini-lesson explanation
- Concept launch linked to the session KCO targets.
- Worked model delivered with explicit think-aloud reasoning.
- Error analysis using this unit's common misconceptions.
Teacher explanation prompts:
- Ask learners to trace one carbon atom through photosynthesis and respiration.
5. Worked examples
Worked example: Diffusion direction
Problem: Which way do particles move in diffusion?
- from high concentration
- to low concentration
- no energy required
Answer: high to low concentration
Worked example: Photosynthesis equation
Problem: Write the word/symbol equation for photosynthesis.
- reactants: carbon dioxide + water + light
- products: glucose + oxygen
Answer: 6CO2 + 6H2O + light -> C6H12O6 + 6O2
6. Guided practice
| Prompt | Answer |
|---|---|
| What controls what enters and leaves a cell? | the cell membrane |
| Which gas is released by photosynthesis? | oxygen |
| Where does cellular respiration mainly occur? | the mitochondria |
7. Misconception contrast
| Misconception | Correct concept |
|---|---|
| Plants only photosynthesize and do not respire. | Plants do both: they make glucose and also respire to release its energy. |
| Diffusion requires energy input. | Diffusion is passive; it needs no energy input. |
8. Exit ticket
Items: SCI10-C-ASM-01, SCI10-C-ASM-02
2/2 concept targets met with no high-risk misconception tags.
9. Semantic marking targets
accepted_concept_match, equivalent_wording, calculation_or_reasoning_evidence, unit_symbol_formula_accuracy, diagram_table_data_interpretation, misconception_identification, next_step_recommendation, human_review_flag
Scored against the accepted concept registry; equivalent wording accepted only when it preserves the concept.
10. Learner-report update
Fields updated: session_evidence, kco_mastery_delta, misconception_recurrence, next_lesson_recommendation, human_review_required
High-impact assessment/reporting decisions require human review.
