Rice Growth Journal

Measure, draw, date. Once a week for four weeks.

Measuring is with a paper strip cut to the height rather than a ruler, which removes the number problem entirely and makes the growth visible as a row of strips getting longer. That row is the best display we produce all year.

The page has four dated entries, a strip mount for each, and a final comparison. It also has the honest note that week one to week two often shows almost nothing, which disappoints a class. Warn them in advance that plants are slow, and the disappointment becomes anticipation instead.

Stick the strips on a wall in order. Parents stop and look at it every time.
