Stem NBS Competition challenge






We see that water resources are not used properly in Turkey and many countries of the world. At the same time, many countries, especially in Southern Europe, face water shortage during the warm summer months and green areas experience irrigation problems. Recovering degraded ecosystems can also benefit from water recovery. Through this course, students will learn about nature-based solutions (NBS) in general and NBS for wastewater treatment in particular. They see that not only will they remove pollutants from rainwater, but also numerous side benefits. Through the project-based learning (PBL) approach, students will prototype storage areas for stormwater harvesting.


Efficient use of rain water, revitalization of vegetation, water management, nature-based solutions, ecosystem, sustainability.


Introduction (leave this section as it is)

“Nature-based solutions (NBS) are solutions that are inspired and supported by nature, which are cost-effective, simultaneously provide environmental, social and economic benefits and help build resilience. Such solutions bring more, and more diverse, nature and natural features and processes into cities, landscapes, and seascapes, through locally adapted, resource-efficient and systemic interventions. Nature-based solutions must therefore benefit biodiversity and support the delivery of a range of ecosystem services.”

To use this Learning Scenario more effectively, teachers are encouraged to:

Integration into the curriculum

Mathematical competence, developing and applying mathematical thinking style to solve a series of problems encountered in daily life. Emphasis is placed on processes, activities and knowledge built on a solid numeracy skill. Mathematical competence includes the ability and willingness to use mathematical modes of thinking (logical and spatial thinking) and presenting (formulas, models, constructs, graphs and tables) to varying degrees.

Aim of the lesson

First of all, I want my students to become entrepreneurs by taking the initiative and to care about nature in their actions in this process. In the process of transforming their thoughts into action; I expect them to maximize their ability to plan and manage projects to achieve goals, as well as creativity, innovation and risk taking. With this project, we want everyone not only at home and at school, but also for the society to support and be aware of nature-based analysis.

I want the society to create ideas to support them by raising awareness of ethical values.

Outcome of the lesson

At the end of the lesson, my students will learn how to harvest rainwater and use it correctly for nature.


Project-based learning method Invention method, trial and error method, brainstorming method, question-answer method and learning by doing method were used collaborative learning.

By investigating the importance of water for all living things, it has been determined that the use of water has increased enormously with each passing century and it has been observed that our country is also faced with the same problem. It has been determined that our water resources should be consumed very carefully in order to prevent our world from entering into a serious water crisis. For this purpose, a house where rain water can be used again and most efficiently was designed. Drawing was made and model design was made. The model was made. Water channels and tanks were added to the model. For the irrigation method to be used in the garden, various pipe arrangements, an intelligent control mechanism that will deliver water to the plants when necessary, and a water pump that will send the water to where it is needed were considered. A wind turbine was added as an energy provider for  these  materials.  Stormwater  Management• Rainwater harvesting systems, in many countries of the world todayAlthough it is implemented, it is in the category of countries with water shortage .In our country, developments on this subject are still sufficient.cannot be said.• In our traditional buildings, rainfall waters are collected in appropriate seasons ,common use of solutions such as when neededIt is known to have been implemented.• There are definitely water wells around historical buildings.• Collection of rainwater next to water wells in traditional housesIt is quite common to use cistern for purpose.• The drought problem that the world and our country have frequently faced in recent yearsThese traditional practices in our buildings are on the agenda again.makes it inevitable that  30 minutes
Our students do puzzle work on the subject:  
METHODS USEDRain water is collected in a tank with parallel pipes on the roof. Rain water passing through the filter system; It is made suitable for use and distributed to the house with water installation. Rain water is filtered and collected in a warehouse with canal systems installed in different parts of the garden. In the system operating with wind energy, water will come to the smart control system with the help of a pump and will be discharged to the soil by drip sprinkling method according to the needs of the soil. The drip sprinkler system is a system that allows the water to be distributed into the garden through water pipes installed in the garden. The system is connected to weather stations with smart control mechanisms and measures the humidity and temperature of the soil and meets the water needs of the plants as a result of some calculations. With the sprinkler system, it is aimed not to kill any plants by using 50% less water.30 minutes

Teacher’s remarks

Students were provided with a comprehensive interdisciplinary study on the subject. Students receive training in new digital tools, NBS practitioners or scientists working in their field (research through Oppla). They had the opportunity to explore Oppla Collections, reflect on new solutions and learn with the STEAM method. The students’ last activity motivated them by applying their imagination while maintaining their science positions. The groups benefited from the development of working social skills. The follow-up evaluation helped Oppla analyze and understand their multiple levels.
