| Learning Outcome(s) | 1.1.2.LO.1 - Apply the solubility rules to analyse and predict the behaviour of common ionic compounds in qualitative analysis | ||
| Content Standard | 1.1.2.CS.1 | ||
| Learning Indicator(s) | 1.1.2.LI.1 - Demonstrate knowledge and application of solubility and solubility rules. Explain the term solubility and describe the factors that affect solubility of substances. Talk for Learning: • Using sample solutions, brainstorm to explain the terms solute, solvent and solution. • With the aid of sample solutions such as sugar solution, mixture of kerosene and water, a mixture of coke and carbon dioxide, describe the various types of solutions based on the state of solute and solvent and give specific examples (solid-liquid, solid-gas, gas-liquid, solid-solid, liquid-liquid, gas-gas solutions). Demonstration: Watch a video or prepare samples of the various types of solutions (unsaturated, saturated and supersaturated). Inquiry-Based Learning: In groups, • Perform experiment to investigate the factors that affect solubility: temperature, pressure, nature of solute and solvent (molecular size and polarity) NB: Stirring or shaking increases the rate of solubility. • Relate the factors to everyday life such as dissolution of salt in soup, sugar in hot and cold water, carbon (IV) oxide in fizzy drinks | ||
| Lesson Focus | Demonstrate knowledge and application of solubility and solubility rules. | ||
| Previous Knowledge | Learners recall related ideas, vocabulary or experiences from earlier lessons and everyday contexts. | ||
| Lesson Objective(s) | Describe the key idea in: Demonstrate knowledge and application of solubility and solubility rules. Apply the idea through guided and independent learning activities. Demonstrate understanding through oral responses, written work or practical performance. | ||
| Essential Question(s) | What chemical model, relationship, evidence or calculation is central to Demonstrate knowledge and application of solubility and solubility rules. Explain the term solubility and describe the factors that affect solubility of substances. Talk for Learning: • Using sample solutions, brainstorm to explain the terms solute, solvent and solution. • With the aid of sample solutions such as sugar solution, mixture of kerosene and water, a mixture of coke and carbon dioxide, describe the various types of solutions based on the state of solute and solvent and give specific examples (solid-liquid, solid-gas, gas-liquid, solid-solid, liquid-liquid, gas-gas solutions).

How can laboratory observations, particle models, equations, graphs or quantitative data be used to explain the chemistry? How can the chemical principle from this lesson be applied to predict the behaviour of a new substance or reaction? | ||
| Pedagogical Strategies | Think-Pair-Share Collaborative Learning Problem-Solving Experimental/Practical Learning Digital/Simulation-Based Learning Model-Based Learning Inquiry/Analytical Learning Worked-Example Fading | ||
| Teaching & Learning Resources | Chemistry textbook/reference materials Whiteboard/markers Learners' notebooks Periodic table Scientific calculators Formula/equation cards or worksheets Gas preparation apparatus or diagrams where available Particle-model materials Test tubes/rack and droppers where available Safe reagent samples or teacher-prepared demonstration materials pH indicators/meters or charts where available Titration/solution preparation apparatus where appropriate | ||
| Key Notes on Differentiation | |||
| Content | Use particle diagrams, colour-coded equations, formula prompts, worked examples and simplified data tables for learners who need support. Extend advanced learners with multi-step calculations, unfamiliar data, mechanism/property comparisons or more demanding analytical interpretation. | ||
| Process | Use mixed-ability grouping with rotating roles such as apparatus manager, recorder, calculator, safety monitor and presenter during practical/problem-solving work. Where apparatus or chemicals are unavailable, use curriculum-aligned simulations, videos, virtual laboratories, data sets and teacher demonstrations without changing the learning objective. | ||
| Product | Allow evidence such as balanced equations, calculations, graphs, molecular/particle models, practical reports, chromatogram interpretations, comparison tables or oral explanations. Assess chemical accuracy, safe procedure, correct units/notation, quantitative reasoning, evidence interpretation and ability to justify conclusions. | ||
| Success Criteria | Learners use correct subject vocabulary. Learners complete the main task with reasonable accuracy. Learners explain or demonstrate how the concept applies in a new situation. | ||
| Homework | Answer structured questions and identify one everyday application of the concept. | ||
| Lesson Activities | |||
| Stage | Teacher Activity | Learner Activity | Assessment / DoK |
| Starter10 minutes | Present a diagram, specimen, data set or everyday situation connected to knowledge and application of solubility and solubility rules and ask learners what they observe. | Share prior knowledge, listen to peers and record the lesson question in their notebooks. | Not provided. |
| Activity 115 minutes | Use a labelled diagram, model, experiment, data table or safe demonstration to explain knowledge and application of solubility and solubility rules. | Observe carefully, record key terms and answer oral questions. | Ask learners to identify the key feature, variable, process or relationship. |
| Activity 220 minutes | Guide groups to observe, classify, measure, compare or explain evidence related to knowledge and application of solubility and solubility rules. | Work in groups to complete the observation, classification, measurement or explanation task. | Review group responses for accurate science vocabulary and evidence. |
| Activity 310 minutes | Give a new case, data set or observation and ask learners to predict or explain the outcome. | Apply the concept to the new case and support the answer with evidence. | Use an exit task that asks for a prediction, explanation or calculation. |
| Lesson Closure | Summarise knowledge and application of solubility and solubility rules and correct one common misconception using learner examples. State one thing learned and complete the exit response. | ||
