Description

Overview:
Cycles in nature are important. Plants especially rely on the recycling and cycling of nutrients. One of the main nutrients plants require and help cycle through the ecosystem is nitrogen. Human activities such as fertilizing lawns and crops change the amount of nitrogen in the ecosystem. In this activity, students will determine the effect varying concentrations of nitrogen have on plant growth by designing and completing a controlled experiment testing the effects of fertilizers on plant growth and the effect of fertilizer runoff on algae growth. Students will develop a hypothesis on the effects of different concentrations of fertilizer on plants and the effects of fertilizer runoff on algal growth. The students will develop and write out a controlled experiment to test their hypothesis. They should include controls, constants, dependent variable(s) and independent variable(s) in their procedure. This lesson was developed by NCDPI as part of the Academically and/or Intellectually Gifted Instructional Resources Project. This lesson plan has been vetted at the state level for standards alignment, AIG focus, and content accuracy.
