Soil-less Agriculture

With the rapidly growing technology in line with the needs of people, industry brought ambient problems with it. One of these problems was the pollution that would disrupt the ecological balance, such as air pollution and water pollution. With the disruption of the ecological balance, the lives of aquatic and terrestrial species were also endangered. While the generations of some living things decrease, the human population continues to increase inversely. So with the increasing human population, people must meet their physiological needs and their nutritional needs. Thus, thanks to soil-less agriculture, we have achieved vertical agriculture, ecological balance and efficient production.

NBS topics covered in the learning scenario:

Sustainable Development
Green spaces and urban transformation;
Economic opportunities and green jobs I asked middle school students aged 10-14 to create a sustainable living space with soil-less agriculture by using waste materials with distance online education in 3 90-minute lessons. Thus, students met the agricultural needs of the growing population. I have enabled them to grow their own crops with landless agriculture in areas where agricultural land has decreased with the decrease of cultivated areas and increase of buildings.

Engineering Design Process

Problem Statement:

We asked our students to observe the agricultural fields around them. They compared the proportion of population in their area of residence with their agricultural land. Thus, they realized that the agricultural lands were scarce. In this case, we asked how you would buy agricultural products. This became our problem situation.

Possible Solutions:

Students researched these problems in their ambient and exchanged ideas with their friends.

Optimal solution:

They planned to create vertical agricultural lands by doing soil-less agriculture.

Making a model:

He made soil-less farmland from simple materials.
Drinking ingredients:
1 5 liter PET bottle Plant; lettuce, beans, corn, lettuce, cotton rope

Test:

The length of the rope was big in the models made. Because the rope needs to touch the water. They tested it for this.

Event process

To create a similar system as in the visual with the plants to be used in the event. Pay attention to the size of the plants you will use for the system, depending on the plant you choose.
Place pet bottles a peak after the event. For this, it may be necessary to use materials such as water pump and air pump to vertically place pet bottles with multiple facilities on top of each other. So vertical agriculture is an example.

Results and 21st century skills

Our students have improved their 21st century skills through events. These are skills such as problem solving, contact, change of ideas, decision making and creativity. The most big of these skills are problem solving skills. Because problem solving skill is an big skill for those who will encounter in their lives to struggle to survive by producing problems.
