HARVESTING RAINWATER

Harvesting Rainwater is the implementation of our STEM lesson plan prepared for the Step by Step STEM etwinning project. Our project aims to increase our students' interest in Science, Technology, Engineering and Mathematics and to ensure the integration of STEM disciplines. My students are 10 years old.

The starting point of our project is water pollution and correct use of water, which are among the environmental problems we encounter in daily life. It is aimed not to experience water shortage and to leave clean water to future generations. 

Students watched "25 litres" documantary with their families.

Discussions were made about what would happen if we were dehydrated, and what could be done to protect the water. my students were caught between using rainwater and gray water. As a result of the voting, they decided to work the rainwater.They investigated rainwater systems. They made drawings with the tinkercad to install a rainwater harvesting system.

The tanks needed volume calculations for their drawings. We learned to calculate the volumes of geometric bodies.

Engineering was required to find out which machines could be used for material selection and water treatment. What is engineering and what engineering fields are there? We learned this from engineers in a webinar.
