Students plant sunflower seeds in plastic cups, and once germinated, these are exposed to different conditions of light levels and/or soil moisture contents. During exposure of the plants to these different conditions, students measure growth of the seedlings every few days using non-standard measurement (inch cubes). After a few weeks, they compare the growth of plants exposed to the different conditions, and make pictorial bar graphs that demonstrate these comparisons.
