Teaching Table

Set out your lesson

Reason about a simple series-circuit model without saying current is used up.

Activity

Comfort with the particular task and communication mode; optional oral/scribed work is recorded separately.

Policy

Check the learner can access these words/materials and prerequisite ideas; historical authorship is not readiness or mastery. If not, demonstrate briefly or revisit the named prerequisite.

Use circuit drawings only for this stage. No mains, coin cells, improvised wiring or unverified hardware. Practical build remains a later adult-supervised kit activity. No printer: view only the active learner card on screen, or an adult copies its exact prompts onto plain paper without answers. Oral pointing/dictation is an access option; record it as adapted/supported and do not claim handwriting from it. Keep adult keys/scripts separate; supply only the current stage.

Use fictional cases and invented identifiers; never record personal conflicts, health, bank details or family spending. Adult prompts/keys are private companion files, never learner links.

Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view. Retain an earlier model only when the current step supplies it as context.

Teaching limits and safe use

These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.

Primary circuit research retrieval failed; domain verification remains open. Buzzers, mixed components, parallel circuits and actual measurements are not covered. ‘Energy shared’ alone is an incomplete explanation.

Use fictional cases and invented identifiers; never record personal conflicts, health, bank details or family spending. Adult prompts/keys are private companion files, never learner links.

Check understanding

Explain why adding more components in series reduces brightness/loudness (energy shared)
Compare circuits with different configurations and predict component behaviour
Give reasoned explanations for observed variations in component function

“If your child adds a second bulb to a series circuit and it gets dimmer, can they explain why the energy is being shared between the two bulbs?”
