EFFECTS OF PLANT GROWTH REGULATORS – SBI3U

Students will design, perform, and document their own experiment examining the effect(s) of a plant growth regulator (PGR). All students are expected to have a basic understanding of a variety of PGRs based on an introductory worksheet. Students are then divided into groups of 2 – 4 to do additional background research on one PGR that they have been assigned. Each group will then design a specific hypothesis about the effects of their assigned PGR using their choice of monocots and/or dicots in different stages of development. Data analysis and write-up can be done collaboratively or individually if used as a summative assignment. Students’ understanding of plant growth regulators and the nature of scientific inquiry can be reinforced with an optional mini-conference after submission.
