What is hydroponics for children? As Study.com says, “Hydroponics is a method of growing plants without soil. The nutrients that plants need to grow are added to the water and then released into the roots of the plants. “So hydroponics for kids is about introducing them to hydroponics and allowing them to see with their own eyes how it works. Teaching kids about hydroponics is a great way to explain that water is a precious resource. This will bring environmental messages home from the start and help develop a curiosity about the world around them. Through this science experiment, children begin to understand the challenges plants face in the environment. Habitat, food supply, ecosystems, reproduction, fertilizers and diseases. These are all important concepts in agriculture and essential learning about nature and basic biology. A system is used in which the roots of the plants are contained in a chamber, which is sprayed continuously or discontinuously with a fine mist of water containing nutrients. The roots of the plant hang in the air and the advantage of this system is that the roots have good access to oxygen. Invented by Richard Spooner in 1983, this system has become an effective method for growing a variety of crops, including seed potato production, tomato, leaf fruit and small lettuce leaf production. Other advantages of aeroponics are that this system can grow a much wider range of plants (some plants don`t like to have their roots continuously in water), plants grow with only a quarter of the nutrients needed for normal hydroponics, and NASA is interested in this system because handling a spray is easier than handling liquids in microgravity. Finally, plants grown using this method can be transferred to soil or other growing media without experiencing stunted growth as they adapt to new conditions.
The main disadvantage is that this system is more expensive to build and maintain than regular hydroponic systems. Another reason introducing kids to hydroponics is so great is that it`s incredibly cheap (and if you have the supplies at home, it`s free), and the supplies are easy to find. Really, many of the components you need are literally in your trash, right now. Experimental plots for hydroponics exist in regions where poor soils and harsh climates are not sufficient to meet the food needs of the inhabitants. Important prospects for the use of hydroponics in agriculture exist in the arid regions of North Africa and the Middle East. (See also agriculture.) As early as the 17th century, laboratory experiments were conducted to determine the factors that control plant growth. In the centuries since, scientists have discovered that plants can be grown in inert substrates or simply in water, as long as the right nutrients are available. The importance of hydroponics was discovered in the 1930s by W.F. Gericke of the University of California, Berkeley. By controlling the nutrient content of crops grown in water baths, Gericke`s laboratory experiments resulted in tomato plants over 20 feet (6 meters) tall.
His discoveries led to the worldwide use of hydroponics in agriculture.

The science of growing plants in water or any substance other than soil is called hydroponics, from the Greek hydro, meaning “water,” and ponos, meaning “work.” Hydroponics, also known as soilless growing, supports the stems and roots of plants. The nutrients necessary for plant growth are provided in the solution that surrounds the roots. Alternatively, you can buy a kids hydroponic kit that is easy to assemble and wax. Hydroponic systems are an incredibly valuable asset to people around the world.
Hydroponic systems don`t have to be expensive or complicated to successfully produce food. Knowing where your food comes from is also more important than most people realize. By helping your child understand hydroponics, they can see plants growing up close and see how plants evolve to produce their fruits or flowers. I love your ideas. I agree that we need to teach them early on how precious water is so that they take it seriously. I will try a hydroponic project with my children. I`ve heard that lettuce seedlings are ideal for a hydroponic system.
