Our project is focused on toys and their importance for children’s development. In this context, we plan to study toys from past to today through a STEAM approach. We will create our toys from various materials, and with various techniques e.g., recycled materials, 3D modelling and 3D printing, robotic, etc. Partners will collaborate in all stages of the project to ensure that students will learn diverse activities in relation to the common theme. The project is implemented in the framework of eTwinning Action STEM 3.0 (#STEM3).
