KiwiBee’s LOOPY classroom edition retains Nicky Case’s CC0 signal engine and adds balancing, reinforcing and grass/rabbit feedback experiments. Use a clear signal-injection button, observe the model levels, restart the experiment, or reveal the drawing tools to change a relationship. Prediction prompts help connect the visible feedback with a causal explanation. The signal animation and model levels are qualitative: they do not fit measured ecological data or forecast a real system.

LOOPY represents qualitative relationships and simplified signal flows. It is not a quantitative forecasting model.
Use the activity controls inside the frame, or open fullscreen for a larger workspace. Ask students to predict a result, test it, and explain what changed. The embedded application starts in English; available upstream language controls are part of the original activity.
