People’s lives depend on clean water. We are getting to the point where we cannot find clean water. change, industrial reasons, and people’s unconsciousness cause these. Therefore, it is very important to manage water resources.

On the other hand, the world population is increasing day by day. Similarly, industrial activities are also increasing. Moreover, we will have uninhabitable environmental pollution. Climate change is also getting worse. Some regions receive less precipitation. That means things are not going well

Also, areas with low rainfall will experience water shortages. Areas with heavy rainfall will exceed the sewage capacity and notably cause serious water pollution.

Particularly ın this STEM learning scenario, we will describe our rainwater harvesting engineering steps to solve.

Daily Life Problem Status :

1-Why is water important for our life?

2-What kind of difficulties would we face without water?

3-What are the water resources?

4-What pollutes the water?

5-Do you want to produce a solution to protect water?

At this stage, brainstorming is done with the students. Moreover, concept maps are prepared. We ask, what are the factors that pollute the water? Additionally, They are asked to make additions both at school and at home.

STEP 1-DISCOVERING

Information is given here to students

Mankind supplies its water needs from surface waters and underground water resources. Especially the most important source of fresh water is precipitation. The same amount of precipitation falls on the earth every year. In our country, freshwater resources are quite limited and only sufficient.

They continue their daily lives and unconsciously increase their water use. To realize this increase, it is necessary to understand what a water footprint is.

It is also possible to calculate the water footprint of an individual in his daily life on a small or large scale. This process evaluates how much clean water is wasted and how much water can be saved.

The water footprint of our students is calculated.

Here are some suggestions for you to save more water:

• Reducing shower time

• Halving textile and food expenditures

• Do not rinse the dishes before putting them in the machine.

• Washing the laundry without prewashing

• Limit your budget for car washes and gas

• Do not leave the tap open

• Paying attention to the efficient use of water resources as well as other resources such as electricity and natural gas.

• Avoiding actions that cause water pollution

• Setting realistic goals with family members to reduce your monthly water consumption

Also, we promised to reduce our water footprint.

Parents have also promised to reduce their water footprint.

STEP 2-DEEPENING

Alice is 8 years old. He has dry days in the city where he lives. Moreover, their water resources are rapidly decreasing. Alice and her family have difficulties in finding water for drinking and cleaning as they suffer from frequent water shortages. In addition, the city where Alice lives can no longer produce as much from agricultural lands as it used to, as problems begin to occur in the irrigation of agricultural lands. On the way to and from school, Alice sees the wooded areas on the way she passed are rapidly decreasing. It doesn’t rain as much as before where they live. Trying to understand the reason for all this, Alice shares her observations with her family, friends, and teacher. They begin to discover how we can use the water we have more efficiently and how we can recover our water through recycling.

***In STEM scenarios, we like to tell the problems with a story.
It is always useful to establish a relationship between a real-life problem and the course content, to turn theoretical knowledge into practice, and to direct our students to research questioning and productivity

Information is given about collecting rainwater in our house. Moreover, a video about the subject is watched.

Small rises in sea level threaten coastal homes, lands, and habitats. Moreover, the risk increases especially in large storms. Floods are inevitable. Additionally, the sea level is rising day by day. We know from recent satellite measurements that Earth’s mean sea level has increased by 10 to 20 centimeters over the past century. But over the last 20 years, annual sea level rise has increased to 3.2 millimeters per year. Namely, that’s almost twice the average value of the last 80 years! In the last century, large amounts of greenhouse gases have been released into the environment.
The atmosphere is caused by the use of fossil fuels, human activities, and various natural events. The oscillation caused the temperature of the Earth’s surface to increase. Eighty percent of that excess heat is absorbed by the oceans. As a result;
Small rises in sea level threaten coastal homes, lands, and habitats. Especially in big storms, the risk increases. Also, flooding is inevitable. Because the sea level is rising day by day.
We decided to solve this problem with STEAM learning.

After examining the photos with the students, we asked the students the following questions in especially:

1-Have a summer house on the beach? Would you like to have a house on the beach very close to the sea? Why?
2-What could be the reason for these images you see in the pictures?
3-What is the reason for the damage to the buildings on the beach?

They analyze the change in the coastline in the years 2009-2014 and 2019. Additionally, reflect and brainstorm the reason.

STEP 1:

The teacher draws the attention of the students by hanging pictures, posters, and posters about coastal erosion that he prepared before the children come into the classroom. Attention was drawn to the issue of coastal erosion. Concerning, the teacher gives the students an experiment on what erosion is.

It increases the awareness and importance of the subject. the teacher opens a related video and asks them to take notes on terms they have not heard before.

They took note of the terms that caught their attention in the video. The homework was given. We said to them; What are the different methods people use to control coastal

erosion?

These;

beach feeding,

sea wall

 rock wall,

gabion baskets,

groins

and breakwaters

STEP 2:

They submitted a research paper. Different methods that people use to control coastal erosion, students. Namely, we found the answers in the research results.

STEP 3:

The story of animals living on the beach

Tern Migratory Bird Sumy could not find the eggs she laid on the beach. But she was sure she had left him here in the dune. Just ahead, he saw the Sea Turtle Carety. The turtle was happy to see it. He asked Carety about his eggs. Sumy was surprised at Carety’s answer. She was looking for her eggs in Ceraty. At this stage, let’s ask the students;

How can we help the heroes in the story?

Why might the eggs be missing? discussed on the subject. Until the answer to coastal erosion comes. The teacher tells. He explains that similar creatures such as Tern and Caretta prefer the sand dunes on the beach to lay their eggs. Sand dunes are also said to be a viable solution to prevent coastal erosion.

STEP 4 – MAKING DESIGNS AS A SOLUTION TO COASTAL EROSION

At this stage, we expect students to decide on their designs. They are also divided into groups according to research topics and interests.

• 1st Group: Works on sea walls.

• 2nd Group: It works in the moles.

• Group 3: It works on Spurs.

• Group 4: Designs by working on beach food and vegetated dunes.

Students were given materials and designed.

Materials :

Cardboard box

Bags, waste materials

Waste plastic cans and bottles

Paper cups, tongue sticks,

Cloth scraps and burlap

adhesive tape,

silicone gun

Rope, gravel, sand,

This STEM activity was held in the “My Bio-Based STEM Activities” project on the eTwinning platform. Portugal, Romania, Turkey are project partners. The project started in September 2020. In our study, we draw attention to environmental pollution, and we make bio-based learnings from these problems with STEM studies. We carried out our activities with hybrid education due to the pandemic.
To describe our activity in a few words; students were encouraged to make bio-based plastic after research plastics they use in daily life. So, what is plastic? What is the harm of plastic to the environment and animals? It was a STEM study where they found answers to the questions in their minds. As a result, they will be able to experience it for life. We did our work in April, of which you will find all the stages below.

Preparation of our STEM project (first step):

Firstly, the students gathered the plastic materials which they use in their homes. Then, they bring them into the class. They investigated the symbols on the plastic materials and drew them to learn them permanently. This enables them to be more curious, after that they learned the meanings of the symbols. Students understood that most plastics are too dangerous. Thus, they started the questioning. They watched various videos about the damages of plastic to the environment and animals. Therefore, their awareness increased. Students learned that plastics produced from petroleum-derived or chemical-derived synthetic polymers cause environmental problems.
