摘要

教授恒星的颜色并不像人们想象的那样简单。要让学生掌握恒星的颜色是按照温度顺序排列的，可能很有难度。本文介绍了一个简单的实验装置，用于指导学生理解恒星的颜色与其温度之间的相关性。此外，该实验装置还有助于探索颜色加法这一主题，向学生演示如何通过使用只发出三原色（红、绿、蓝）的 RGB LED 来复制恒星的颜色--光谱颜色。实验使用了 Arduino 微控制器板、RGB LED 和 LCD 显示屏。葡萄牙一所私立学校的 53 名七年级学生参加了这项活动。结果表明，学生们对这项活动反应积极，在动机和认知方面都取得了成功。总体结果凸显了该活动在向学生传授新知识方面的有效性。

Colour and temperature of the stars: a demonstration using Arduino

Teaching the colour of stars is not as trivial as one might think. It can be challenging for students to grasp that the colour of stars follows a temperature sequence. This paper introduces a simple experimental setup for instructing the correlation between a star’s colour and its temperature. Furthermore, the experimental setup facilitates the exploration of the topic of colour addition, demonstrating to students how to replicate the colour of a star—a spectrum colour—by employing an RGB LED that emits only primary colours (red, green, and blue). The experiment utilised an Arduino microcontroller board in conjunction with RGB LEDs and an LCD display. The activity was conducted with 53 7th-grade students from a private school in Portugal results suggest a positive reception, indicating success in both motivational and cognitive aspects. The overall outcomes underscore the effectiveness of the activity in imparting new knowledge to students.

期刊介绍： Physics Education seeks to serve the physics teaching community and we welcome contributions from teachers. We seek to support the teaching of physics to students aged 11 up to introductory undergraduate level. We aim to provide professional development and support for teachers of physics around the world by providing: a forum for practising teachers to make an active contribution to the physics teaching community; knowledge updates in physics, educational research and relevant wider curriculum developments; and strategies for teaching and classroom management that will engage and motivate students.
