Resolution of Light Transmission via Arduino-Based STEM Education Material

Introduction

Resolution of light transmission via arduino-based stem education material. Arduino-based STEM material helps students measure light transmission/absorption through transparent materials. Simple, inexpensive experiments foster dynamic STEM skills.

Abstract

This study reports a basic experimental procedure to measure light transmission through some transparent materials through Arduino microprocessors. The basic experimental material is made up of materials used daily by elementary students, and the procedure is very simple and can surely be employed for teaching activities as STEM education material. The STEM material particularly focuses on transmission rates as a function of the thickness of the material. The absorption rates are experimentally measured using a specially designed box with two separated parts with a small window and an Arduino Uno microprocessor connected to an appropriate light detector structured as STEM education material. The experimental resolutions are managed for two materials, namely blue acetate and red acetate, with different thicknesses. The absorption coefficients are found to be 2.89 mm-1 for blue acetate and 1.54 mm-1 for red acetate. This work offers inexpensive teaching material that can create an education environment where students can feel dynamic and encompass the acquisitions of Science, Technology, Engineering, and Mathematics.

Review

This study presents an innovative and highly relevant contribution to STEM education, particularly for elementary students, by introducing an accessible Arduino-based experimental procedure for measuring light transmission. The authors propose a basic setup utilizing everyday materials, effectively demonstrating how fundamental scientific concepts, such as light absorption as a function of material thickness, can be explored in a hands-on and engaging manner. This approach addresses a critical need for practical, interdisciplinary learning experiences that make scientific principles tangible and exciting for young learners. The methodology described involves a specially designed measurement box integrated with an Arduino Uno microprocessor and a light detector, allowing for the quantitative assessment of light transmission. The work specifically investigates blue and red acetate materials of varying thicknesses, reporting absorption coefficients of 2.89 mm⁻¹ for blue acetate and 1.54 mm⁻¹ for red acetate. While the abstract states that "experimental resolutions are managed," the full paper would benefit from elaborating on the specific measures taken to ensure the robustness and accuracy of these findings, especially given the educational context and potential for student-led data collection. In conclusion, this work offers a commendable and inexpensive teaching material that holds significant promise for enhancing STEM education. By seamlessly integrating Science (light physics), Technology (Arduino and sensors), Engineering (design of the experimental apparatus), and Mathematics (data analysis and coefficient determination), it successfully creates a dynamic learning environment. The proposed material has the potential to foster scientific curiosity, critical thinking, and a deeper appreciation for the interconnectedness of these disciplines among elementary students, making it a valuable resource for educators seeking practical and impactful STEM activities.
