Weekly Learning Plan
Subject	Chemistry	Week	7
Duration	60 minutes	Form	SHS 1
Strand	PHYSICAL CHEMISTRY	Sub-Strand	MATTER AND ITS PROPERTIES
Learning Outcome(s)	1.1.1.LO.1 - Use the knowledge and understanding of the scientific practices in Chemistry to explain the structure of the atom as well as the stability of its nucleus 1.1.1.LO.2 - Use the mole concept to determine the amount and quantity of various substances involved in chemical reactions 1.1.1.LO.3 - Write mole ratios for chemical equations and apply it in quantitative analysis 1.1.1.LO.4 - Use the kinetic theory of matter to explain the behaviour of solids, liquids and gases under different conditions and describe the laboratory preparation of gases as well as their uses in everyday life
Content Standard	1.1.1.CS.1 1.1.1.CS.2 1.1.1.CS.3
Learning Indicator(s)	1.1.1.LI.9 - Describe radioactivity, the properties of radiations and compare isotopes based on their stability as well as their applications in everyday life. Through a Class Discussion: • Explain relative atomic mass and relative molecular mass. • Describe the principal parts of a mass spectrometer and explain how it works, using charts or pictures or models 1.1.1.LI.1 - Demonstrate an understanding of the mole concept and its significance to the quantitative analysis of chemical reaction. Explain relative atomic mass and relative molecular mass. Prior to the lesson: Find-out why carbon-12 isotope is used as a reference scale for measurement. Activity-Based learning: Use a beam balance to demonstrate the determination of the mass of an element/compound by placing the standard (Carbon-12) in one pan and the mass to be determined in the other pan
Lesson Focus	Describe radioactivity, the properties of radiations and compare isotopes based on their stability as well as their applications in everyday life.
Previous Knowledge	Learners recall related ideas, vocabulary or experiences from earlier lessons and everyday contexts.
Lesson Objective(s)	Describe the key idea in: Describe radioactivity, the properties of radiations and compare isotopes based on their stability as well as their applications in everyday life. 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 Describe radioactivity, the properties of radiations and compare isotopes based on their stability as well as their applications in everyday life. Through a Class Discussion: • Explain relative atomic mass and relative molecular mass. • Describe the principal parts of a mass spectrometer and explain how it works, using charts or pictures or models; Demonstrate an understanding of the mole concept and its significance to the quantitative analysis of chemical reaction. Explain relative atomic mass and relative molecular mass. Prior to the lesson: Find-out why carbon-12 isotope is used as a reference scale for measurement. Activity-Based learning: Use a beam balance to demonstrate the determination of the mass of an element/compound by placing the standard (Carbon-12) in one pan and the mass to be determined in the other pan? 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 Worked-Example Fading
Teaching & Learning Resources	Chemistry textbook/reference materials Whiteboard/markers Learners' notebooks Periodic table MATERIALS ICT devices Household items with labels Chemical containers with labels Containers having chemical assay Personal protective equipment (goggles, laboratory coat/apron, hand gloves etc) Hydrogen peroxide Hydrazine Oxidising materials Flammable materials Acetic acid and nitric acid Worksheets with incomplete nuclear reactions with prepared mark schemes Worksheets of empty orbital diagram for learners to complete Worksheets with blank column for numbers of proton, neutrons and electrons Fire extinguisher Fire blanket Material for setting fire Markers Cardboard Graph sheet Scientific calculators Formula/equation cards or worksheets 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 matter and its properties 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 matter and its properties.	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 matter and its properties.	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 matter and its properties and correct one common misconception using learner examples. State one thing learned and complete the exit response.
