Activity: Macro-nutrient Manipulative
January 09, 2014 | 10:01 am
As students at the secondary level learn about the 17 essential nutrients plants require, it important to emphasize the macronutrients, as they are the nutrient present in a relatively large amount to ensure the health of the plant. This 30 minute paper manipulative activity is a nice way to reinforce Lesson 4 of Nourishing the Planet in the 21st Century high school curriculum. Students can review concepts about NPK, how they affect plants, and their deficiency and toxicity symptoms.
- Two sheets of construction paper per person
- Glue Sticks
- Writing Utensil
- Fold one sheet of construction paper in half horizontally.
- Then fold the paper three times vertically and then unfold the paper.
- Cut the paper on the three folded vertical lines.
- Then fold a glue line so once attached to the other sheet of construction paper, the both ‘pages’ can flap (see visual).
- Top flap: Nitrogen
Inside first flap, behind Nitrogen:
- – Component of proteins and nucleic acids.
- – Required for chlorophyll production.
Top Flap: Phosphorus
Inside first flap, behind Phosphorus:
- – Component of nucleic acids and some proteins
- – Required for energy transfer.
- – Important for seed germination and water use.
Top Flap: Potassium
Inside first flap, behind Potassium:
- – Required as a regulator involved in:
- – Efficient use of water
- – Transfer of food
- – Protection against stresses
Next flaps: See visual: Deficiency and Toxicity on different flaps.
