Soil Water and Rice Trial

One variable, three replicates, four weeks, measured.

Replication is the new idea here. One plot proves nothing because plants vary, and three plots per condition lets a class see variation and still find a signal. That is a large step up from the grade two fair test and grade five is ready for it.

The page has the trial design, the measurement protocol, a results table with space for averages, and a conclusion frame that asks about confidence. Some results are clear and some are within the noise, and saying so honestly is the mark we care about.
