This lesson is managed for kids in nursery (3-4 years old), so they can learn through playing about STEAM. I'm going to concentrate in the area of construction and recycling because in my opinion, kids can learn a lot using those things.Children in early childhood can develop a love for STEM and a feeling of efficacy for their own abilities that can support their learning. Using their own toys we can capture the child's love for science, math, engineering, arts and technology. Also encouraging them to explorate and to be curious through insightful questions and celebrating secces as well as failure, so they can go on and on investigating. Goal:Create obstacles of all type to a course that the kids have to build in their neighborhood, in orther to learn about how important it is to mantaine clean the streets, the green parts and the enviroment.Materials:Toys for construction (legos, blocks, among others).Recycled materials for construction (boxes, toilet paper tubes, paperboard, among others).Paper, colored pencils, tape and other tools to decorate the course and neighborhood.Toys to play after you finish with your construction (vehicles, persons, animals and plants).
