A cause and effect graphic organizer is a visual thinking tool that connects why something happens to the results it produces. Causes appear before a central event, effects follow it, and arrows show the direction of the relationship. Event-chain layouts show how one effect can become the next cause.
The relationship is not always one-to-one. A historical event may have several causes and several consequences. A science process or story may be better shown as a chain in which each effect becomes the next cause.
Use the organizer before writing to collect evidence, during reading to track relationships, or after a lesson to check whether learners can explain more than a simple sequence. Evidence + mechanism mode adds a why field to every relationship, so the exported worksheet records the reasoning behind each arrow.
Cause
The action, condition, or reason that helps produce an event.
Central event
The outcome or turning point the organizer is trying to explain.
Effect
A result or consequence that follows the event.
Mechanism + evidence
The explanation of how the cause produces the result, supported by text details, observations, or facts.
