• Observing differences between spinners with centrally and off-centre positioned holes.
• Understanding why an object may float or sink.
• Recognising that weight alone does not determine whether an object floats or sinks.

• Identifying weaknesses in a boat's design and suggesting improvements.

Learners Needing Support

Identify learners who:

• Have difficulty making predictions before an experiment.
• Cannot distinguish between observations and explanations.
• Need help completing observation tables.

Identification method: Teacher observation, oral questioning, practical performance and review of completed activity tables.

Suggested Remedial Strategies

• Repeat demonstrations using familiar objects.
• Provide guided opportunities to spin objects and observe their movement.
• Allow learners to predict and test floating and sinking using a small number of objects.
• Use picture cards and partially completed observation tables.
• Pair learners who need support with peers who can demonstrate the task.
• Provide additional opportunities to modify and retest spinners and boats.
• Ask learners to explain observations in simple oral sentences before writing them.

Enrichment for Advanced Learners

• Design spinners using different shapes and compare their performance.
• Investigate different boat designs using available materials.
• Identify possible reasons for a boat tipping over and propose improvements.
• Conduct an additional floating-and-sinking investigation using suitable objects.
• Present findings through drawings, diagrams and oral explanations.

Post-teaching reflection: Actual learning difficulties and the number of learners requiring support will be recorded after classroom assessment.
