# Construction of a Model of the Solar System with Temperature Control for Visually Impaired Students

## TL;DR

This paper describes the development of an accessible, low-cost educational model of the Solar System with temperature control features, aimed at improving astronomy teaching for visually impaired students.

## Contribution

It introduces a novel tactile and thermal model using Peltier elements, tailored for visually impaired learners, with detailed design and implementation procedures.

## Key findings

- Effective tactile and thermal feedback for learning astronomy concepts
- Low-cost and accessible materials used in model construction
- Successful presentation at a national science exhibition

## Abstract

In this work, we present a study carried out to develop a didactic kit based on the use of touch and thermal receivers for the teaching of Astronomy. The proposal arose in the face of the difficulties encountered in the search for experiments capable of presenting the best concepts involved in the teaching of Astronomy for visually impaired people. The equipment consists of the use of a model with hemispheres with Peltier pellets for simulation of temperature scale of planets of the Solar System. The research was based on the use of accessible and low-cost materials. All the materials used and the assembly of the equipment are described in this work, since the design until the application of the final product for students. This experiment was part of a set of pedagogical equipment presented at a scientific exhibition for the visually impaired during the 15 a National Science and Technology Week in the city of Juazeiro do Norte in the State of Cear\'a.
