Color it is viewed, may alter its perception considerably; for example, a low-intensity orange-yellow is brown, and a low-intensity yellow-green is olive green. The color of an object depends on both the physics of the object in its environment and the characteristics of the perceiving eye and brain. Physically, objects can be said to have the color of the light leaving their surfaces, which normally depends on the spectrum of the incident illumination and the reflectance properties of the surface, as well as potentially on the angles of illumination and viewing. Some objects not only reflect light, but also transmit light
SCALE-UP boards nearby. Each team has a laptop in case they need web access. The original design called for 11 round tables of nine students, but many schools have smaller classes while a few have even larger ones. Smaller classes, particularly those in high schools, have also been using D-shaped tables that seat six students. SCALE-UP SCALE-UP is a learning environment specifically created to facilitate active, collaborative learning in a studio-like setting. Some people think the rooms look more like restaurants than classrooms. The spaces are carefully designed to facilitate interactions between teams of students who work on short, interesting tasks.
