1.4 Nutrients as an input


Understanding chemical compounds gives us the ability to know what those compounds are made of.

Big Idea

Plants need inputs to grow! Chemical compounds are one of those inputs!



  • Agriculture: the science, art, or practice of cultivating the soil, producing crops, and raising livestock and in varying degrees the preparation and marketing of the resulting products.
  • Chemical Compound: a material made up of two or more elements.
  • Chemical Formula: a set of chemical symbols showing the elements present in a compound and the ratio of each element.
  • Deficiency: a lack or shortage.
  • Element: a substance that cannot be broken down into any other substance. Every element is made up of its own type of atom.
  • Germinate: to begin to grow; to sprout.
  • Microgreens: a very small, young, and tender edible leaf/plant showing 2 tiny leaves; a single microgreen is called a seedling.
  • Input: something that is put in; a variable added into a system.
  • Resource: a source of supply or support.
  • Elements: the fundamental substances that consist of atoms that constitute all matter.
  • Molecule: the smallest particle of a substance that retains all the properties of the substance, and is also composed of one or more atoms.
  • Nutrient: a substance or ingredient that promotes growth, provides energy, and maintains life.
  • Observation: a statement based on something one has noticed using their five senses.
  • Photosynthesis: the process by which green plants use sunlight to make food from carbon dioxide and water.
  • Seed: the fertilized ripened ovule of a flowering plant containing an embryo and capable of germinating; (similar to an “egg” that can “hatch” under the right conditions).
  • Soilless Media: a material used instead of soil that provides plants with physical support, allows the water flow, and serves as source of nutrients to allow the plant to grow.
