Learning Outcome(s)2.1.1.LO.1 - Describe the nature and uses of different liquids in the Lives of humans
Content Standard2.1.1.CS.1
Learning Indicator(s)2.1.1.LI.3 - Describe how to measure the concentration of solutions and how to use the pH scale to identify the concentration of acids and bases/alkalis. Problem-Based Learning: In small mixed-ability groups, set up experiments for learners and supervise groups while providing support for learners who need extra support to prepare solutions of various concentrations and to identify acids, bases or alkalis using the pH scale
Lesson FocusDescribe how to measure the concentration of solutions and how to use the pH scale to identify the concentration of acids and bases/alkalis.
Previous KnowledgeLearners recall related ideas, vocabulary or experiences from earlier lessons and everyday contexts.
Lesson Objective(s)Describe the key idea in: Describe how to measure the concentration of solutions and how to use the pH scale to identify the concentration of acids and bases/alkalis. Apply the idea through guided and independent learning activities. Demonstrate understanding through oral responses, written work or practical performance.
Essential Question(s)What scientific principle or process is central to Describe how to measure the concentration of solutions and how to use the pH scale to identify the concentration of acids and bases/alkalis. Problem-Based Learning: In small mixed-ability groups, set up experiments for learners and supervise groups while providing support for learners who need extra support to prepare solutions of various concentrations and to identify acids, bases or alkalis using the pH scale? What observation, experiment, model or measurement could test/explain it? How can the science be applied safely to a new everyday or community problem?
Pedagogical StrategiesInquiry-Based Learning Experiential/Practical Learning Collaborative Learning Problem-Based Learning Model/Simulation-Based Learning Scientific Discussion
Teaching & Learning ResourcesGeneral Science textbook/reference materials Whiteboard/markers Learners' notebooks Basic science apparatus/materials where appropriate Local material samples
Key Notes on Differentiation
ContentUse diagrams, real materials, partially completed tables and stepwise practical instructions for learners needing support. Extend advanced learners with unfamiliar data, multi-step calculations or design/improvement tasks.
ProcessUse mixed-ability groups with rotating science roles such as observer, recorder, measurer and presenter. Where apparatus is unavailable, use simulations, models, videos or teacher demonstrations while keeping the same objective.
ProductAccept appropriate evidence such as practical records, diagrams, calculations, models, data tables/graphs or short scientific explanations. Assess scientific accuracy, safe procedure, evidence interpretation and justification.
Success CriteriaLearners use correct subject vocabulary. Learners complete the main task with reasonable accuracy. Learners explain or demonstrate how the concept applies in a new situation.
HomeworkComplete a short application task connected to the week's learning indicator.
Lesson Activities
StageTeacher ActivityLearner ActivityAssessment / DoK
Starter10 minutesPresent a diagram, specimen, data set or everyday situation connected to science and materials in nature and ask learners what they observe.Share prior knowledge, listen to peers and record the lesson question in their notebooks.Not provided.
Activity 115 minutesUse a labelled diagram, model, experiment, data table or safe demonstration to explain science and materials in nature.Observe carefully, record key terms and answer oral questions.Ask learners to identify the key feature, variable, process or relationship.
Activity 220 minutesGuide groups to observe, classify, measure, compare or explain evidence related to science and materials in nature.Work in groups to complete the observation, classification, measurement or explanation task.Review group responses for accurate science vocabulary and evidence.
Activity 310 minutesGive 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 ClosureSummarise science and materials in nature and correct one common misconception using learner examples. State one thing learned and complete the exit response.
