THE

KRATKY

METHOD

Description 

The Kratky method is a hydroponic gardening technique that uses water to provide plants with nutrients. It's a passive method that doesn't require pumps or electricity.

Instructions 

Follow the activities slides to assemble and begin the growing process of a Kratky hydroponic system. Students can either work individually or in pairs to assemble the jars. Additional, in-depth explanations of this system can be found here and here

Deliverables

Along the process of constructing your Kratky jars, capture pictures of the assembly. Make sure both the pH and PPM of the water measured. Once completed, capture a picture of your seedling at each stage of growth. Ensure your jars are left in an area of adequate sunlight or use a grow light positioned 12" above your plant. 

GROWING

IN SOIL

Description 

In order to increase the success of fruits and vegetables planted outdoors, we will first germinate seedlings in biodegradable cups to then be transferred to our raised-bed gardens. 

Instructions 

Follow the slides to assemble a germination cup to then be kept in a warm, sunny place for 2-3 weeks with consistent watering. Once the seedling is stable, transfer the plant to the outdoor garden. 

Deliverables

Document the created germination cups as well as daily progress of the growth of the plants.

Germination - the process of a seed starting to grow after a period of dormancy. Moisture is required for seed germination.

Photosynthesis - the process by which green plants use sunlight to create and store foods from carbon dioxide and water with the byproduct of oxygen.


Hydroponics - the technique of growing plants using a water-based nutrient solution rather than soil

Solution (chemistry) - a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component, often water (the solvent).



pH Level - a measure of how acidic/basic a liquid is. The range goes from 0 - 14, with 7 being neutral. Lemons are very acidic (pH of 2) Bleach is very basic (pH of 13) 

PPM - "Part Per Million” is a unit of measurement used to describe very small amounts of something in a much larger amount of something else. 1 per 1,000,000 


Full Spectrum Light - light that covers all wavelengths of the electromagnetic spectrum that are useful to plant or animal life. Sunlight is considered full spectrum

Transpiration - the passive process of water movement through a plant and its evaporation from its leaves. It enables mass flow of mineral nutrients from the roots.


Macronutrients - the nutrients we need in larger quantities that provide us with energy: in other words, fat, protein and carbohydrate.

Micronutrients - mostly vitamins and minerals, consumed in very small amounts. antioxidants, electrolytes, and organic acids.


Antioxidants - Antioxidants inhibit oxidation, a chemical reaction that can produce free radicals. Free radicals degrade living tissue such as brain cells. 

Anti-inflammatory - a substance or treatment that reduces inflammation or swelling. Inflammation causes a long list of disorders: arthritis, asthma, blindness, cancer, and diabetes.


Mitosis - a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.

Transpiration - the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. 


GARDEN

PLANTING

STRATEGY

Description 

Before planting in our raised-bed gardens, we will research and develop a strategy for which plants to plant and in what quantity. We will make our decisions based on the dietary health benefits of the plants. 

Instructions 

On a large (36" x 36") sheet of butcher paper, as a group of four, we will create a color coded plan view of our garden that is annotated with the name of each plant and its health benefits. 

Deliverables

Once our annotated garden plans are completed, we will present our research and design process to the other groups. 

NFT

HYDROPONIC

SYSTEM



Description 

The Nutrient Film Technique (NFT) is a hydroponic system that uses pumps to circulate a thin film of nutrient solution through shallow channels.

Instructions 

Assemble the hydroponics kit with your fellow classmates making sure to understand what each part of the system does and where it goes. 

Deliverables

At the end of the assembly process, you should be able to explain how the system works and why it has all of the parts that is does. Conclude the studio session with a conversation about how it works. 

Diagramming The Kratky Method

DIAGRAMMING THE KRATKY

METHOD

Kratky Jar Template.pdf

Description 

Diagramming the simple, passive Kratky jar system will allow us to understand the essential components to any hydroponic plant growing system.

Instructions 

Print the Krarky Jar Template attached PDF for each student and as a group step through the different elements of the Kratky method hydroponics by drawing and annotation. 

Deliverables

Each student should end up with a completed diagram to serve as a reference key of the essential components of hydroponic plant growth.

Description 

The reason we are exploring how to grow food is so that we can eat it. In this activity, we we learn the basics of healthy dietary habits. 

Instructions 

Print the attached PDF to follow along with the slide's activities. 

Deliverables

At the end of this activity, we should have a basic understanding of macronutrients and micronutrients.
