Here are a couple of examples of models. I think flow charts would also fall into this category. But here is the point: what should be included in the category of "model"? Sometimes the relationship between a model and an example, or an experiment, is not clear.

Please search the internet for examples of models, metaphors (any kind of non-literal speech), experiments, etc. Post them here, with a link to their source. (Please note: the source website might not be useful, or appropriate, or whatever - but we need to link to the source website, just to respect copyright.) Make some comments about whether your example is an example, a model, a metaphor, an experiment, or something else.
