Make the causal links visible - Online practice 2
Read the information, then answer the questions. An adult may read the instructions aloud. Show your working where asked.
Read before answering
Supplied process facts for a paper shadow model: an opaque card blocks some light from a torch; a darker region forms on the screen behind it. Instruction: 'Place the card in the beam.' Use only this model, without claiming it covers every real system. An explanation links cause and consequence; an instruction asks someone to act. This is a writing exercise, not a request to build electrical or other equipment.
