Weather and Plant Growth Log

Daily weather, weekly growth, one page, four weeks.

The correlation is there and it is not perfect, which is the honest and useful outcome. Plants grow after rain, mostly, except when they do not, and the exceptions are worth discussing rather than smoothing over.

Grade three can handle a messy result if you frame it as normal rather than as a failed experiment.

The page has the daily weather grid, weekly measurement rows, and a comparison prompt. It also has a note about the rainy season, where every day is the same and the correlation disappears entirely. Run it at a transition if you can, or accept a boring month and discuss why it was boring.
