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.

BASIC PROBLEM

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.

Furthermore, We also gave responsibility to our parents.
Moreover, They will calculate the 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.

STEP 3- ENGINEERING OF THE ROOF HARVEST FROM RAINWATER

    ACTIVITY:

Afterward, students are divided into groups according to the results of their research and their interests.

  • 1.Group Recycling and harvesting of water used in the kitchen.
  • 2.Group Recovery and harvesting of rain water.
  • decides to work on the use of recycled water in agriculture, cleaning, etc.

 EXPERIMENTAL MATERIALS:

Cardboard box

Straws

waste plastic cans and bottles

paper cups

adhesive tape,

silicone gun

rope,

cardboard,backdrop cardboard,crafts paper, filter paper.

STEP 4- EVALUATION

Each group shares the engineering design with the other groups and their teachers. Students have the opportunity to examine products designed by other groups. The aim here is to enable students to evaluate their products by comparing them with other products. The spokesperson of the group briefly explains the product in class. If the school conditions are suitable, the prepared products are exhibited and shared with other students and teachers in the school. We were able to hold our school exhibition. It was really amazing.
