Lesson Plan 2: Investigation and Research

Overview
Students will develop an understanding of hydroponics and aquaculture. Lessons will include information and descriptions about various hydroponic systems and their components, plants and how the subsystems work together. Students will also explore aquaculture and how fish and other marine animals are raised in self contained units. Students will the explore how the two can be combined to form an aquaponics system.

Objectives

Students will be able to:
  1. Describe what a hydroponic system is and its subsystems.
    • Identify the two primary systems of hydroponics production, and the methods that fall under each one.
      • Wick, NFT, Flood & Drain, Drip, Aeroponic
    • Draw and label the parts (subsystems) of multiple hydroponics systems
      • Control, Filter, Pump, Drain, Water, Lighting, Inert Medium, Aeration, Biological Components
    • Discuss four types of tradeoffs presented by generic soil farming and open water fishing
    • Calculate nutrient mixtures to be added to water in a hydroponics system

  2. Describe what an aquaculture system is and its subsystems.
    • Control, Filter, Pump, Drain, Water, Lighting, Inert Medium, Aeration, Biological Components

  3. Produce a simple hydroponics wick system.
    • Identify material suitable for wick systems.
    • Build a Wick system from a kit.

  4. Explain the maintenance procedures for ensuring a healthy relationship between plants and fish in an aquaponics system in terms of:
    • Light, Nutrients, Aeration, Temperature, Water Quality, Flow
    • Be able to describe what a self-contained aquaponics system is as well as the desired qualities of plants and fish required for a self-contained aquaponics system.
    • Identify appropriate materials to be used in aquaponics environment
Materials and Resources
  • Computers with internet access
  • Power Point: Introduction to Hydroponics
  • Projector/DVD player
  • Introduction to Aquaponics Video
    • In this "how to" video, Chris Anderson explains the fundamental materials, process and scientific knowledge that a beginning teacher and their students will need to know to be successful in this unit. Broken into chapters for ease of use, the material will also be available online in the form of streaming video.
