Setup
Print or hand-copy the essential prompt for Scratch Ecosystem Food Web Game, then set out only paper, pencils, and the common or recycled items needed for one test. Use a tabletop representation whenever the original version mentions a room, specialized device, or digital tool; the learning comes from the decisions and evidence, not elaborate scenery.
Activity
- Define the central success test in Scratch Ecosystem Food Web Game and make a paper planning sheet for the inputs, actions, and expected result.
- Represent the system without electronics by using labeled cards, paper controls, tokens, a ruler, or a student acting as the device; follow the same cause-and-effect rules described in the project.
- Run at least three cases, including one difficult or unexpected case, and record input examples, operating rules, predicted outputs, and actual outputs.
- Revise one rule, layout, mechanism, or decision after the failed case, repeat it, and explain with the recorded evidence whether the change worked.
Done when: The group has completed Scratch Ecosystem Food Web Game when it can add a win/lose condition and playtest with a classmate, then narrate what happens when one species is removed and point to the observation, measurement, comparison, or trial that supports its conclusion.
