# RECYCLING

Science-Mathematics Art Activity:

This project STEM event is one of the few activities of the European eTwinning project “Discovering STEM in Recycling”, in which Turkey, Estonia, Lithuania, Latvia, Poland and North Macedonia participated. The theme of the project is “We learn stem from Recycling”. First of all, we created a STEM center for our classroom to draw attention to the issue of waste.

We build robots that collect wastes.
The children watched a video explaining how to collect, classify and evaluate waste. They designed recycling bins to collect waste paper at home.

I also designed a recycling machine for students. In this way, my students learned in a fun way how waste becomes used back.

Design Process for the collection, separation and recycling of waste:

Guys, I asked the question: How can we create a robot to collect waste? What materials can we build this robot with? asked.
I got the kids to pay attention to the STEM Center and the materials that were there. Then we examined the materials together to be used.

Materials: Research Materials
Magnifying glass
Pet bottles
Straws
Paper and pen
Various sizes of stones
Paper rolls
Packaging waste (boxes, drums, etc.)
Bottle caps
Tin cans
Glass vials
Sticks or twigs
The children discovered the materials from scratch. What is the problem, what is the purpose, what are our rules so that the subject does not fall apart? I asked them to explain what they knew by asking questions.
I stated that there will be some limitations in the design that children will make in the first place.

Limitations and Criteria:
I asked my students the following question: How can we collect and recycle the waste in our environment that pollutes our nature?

The goal: to invent a robot that can pollute our environment and collect waste materials to make it reusable. Also, this robot should be an environmentally friendly robot that can recycle waste.
Rules: inventing an eco-friendly robot from waste materials

• There must be at least 1 material from nature for our robot.
• No material other than the specified materials will be used.It will not go beyond the designated area.

Our environmentally friendly robot we designed will have a hopper to collect waste. Assessment: Students After this work, we sought help from an Environmental Engineer and gave students an online Recycling Tutorial.

## EVALUATION:

In the evaluation process, pictures drawn by children, concept maps, posters, documents, etc. It is examined with the children. The following questions are directed to the children.
The answers given by the children are noted again and compared with the observation forms of the children in the process. Later works are exhibited in the STEM center.

What was our problem situation?

Have you been interested in the problem?

What was our problem situation?

What have we done to solve the problem?

Could the problem be solved?

What did we pay attention to while drawing the design?

Was the design we made close to the design we drew?
