Vernier: Go Direct Light and Color

Introduction The Go Direct Light and Color Sensor is a powerful and versatile light sensor that measures visible light, the ultraviolet electromagnetic spectrum, and does color analysis. As seen in the video, by using an RGB color sensor, the relative primary colors of light can be detected with this device. As seen in Image 1., […]

The children have used magnifiers many times before but they are always intrigued, and maybe even a little surprised, when things “get bigger”. One child asked why the […]
