H2 GrOw Challenge

We need food to survive. But food security is a problem around the world, and at home. Get creative as you design a sustainable living environment for aquatic life while growing food in this Purple Plow Challenge!

H2 GrOw Challenge

Challenge Rationale

Students locally can contribute to the impact problems of population growth, access to resources, limited space for growing food, and year-round plant-based food production. After thoughtful research to evaluate how these challenges exist globally and locally, students will design, build, and utilize a growing structure that can be used in their unique location or situation to help maximize the availability and access of food given the extensive growth in population and limitations of space. The final product will be a functioning aquaponics system.

Establishing the Challenge

Identifying the Problem

According to the USDA “food insecurity” is defined as a household’s consistent access to adequate food being limited by a lack of money and other resources at times during the year. Often, we think of this as being a problem affecting only third world countries. However, Feeding America shares that 42.2 million Americans live in food insecure households, including 32.8 million adults and 13.1 million children. Often, we think of individuals that are living with food insecurity to be homeless or easy to identify, but they could be your neighbor or even a classmate. What can we do to help solve this problem? The best way to start solving this problem of food insecurity is to create sustainable local food systems.

Response to Problem

With the challenge of feeding 9 billion people by 2050, your team has been selected to design a prototype and construct a life-size model of a system that will integrate the use of waste from an aquatic animal growth system as a beneficial nutrient for a plant growth system.

This system must address the following needs:

  • Produce a plant-based food source
  • Produce an aquatic animal-based food source
  • Hold, at maximum, 20 gallons of water
  • Produce weekly documentation of water quality by pH

Success will be determined by

  • Harvest an edible food product within 90 days or show progress of plant and animal
    growth within the timeframe allotted for your specific situation
  • Create, construct, and maintain an environment that is suitable for aquatic animal life
    within 90 days
  • Produce a presentation
