An experiment in plant nutrient stress to teach plant physiology and the scientific method.

Science classes are greatly improved when students can perform guided inquiry activities, rather than only listening to lectures. Here, we describe a plant physiology experiment that was implemented in a fifth grade classroom to teach plant biology, plant growth responses, and the scientific method. Students planted 14 morning glory seeds and, after germination, applied a fertilizer treatment to 7 plants and an unfertilized control to 7 plants. Every week, students measured height, number of leaves, and length of the largest leaf, and recorded results. After 30 days, students harvested the plants and measured root length and biomass, as well as above ground biomass. There were substantial differences between the fertilized and unfertilized treatments: the unfertilized plants were smaller and had longer roots. This project would be appropriate for middle school grades; it fulfills Next Generation Science Standards in biology and engineering. The experiment could be easily adapted to higher grades; for example, students could be involved in developing the experimental design and could learn basic statistics, including averages and variances, but also t-test and analysis of variance.
