Explore optical phenomena and experiment with light! The model of the solar system provides a visual explanation of the phases of the Moon, as well as solar and lunar eclipses. Optical lenses with different focal lengths, mirrors, LED barriers, and a large number of components allow students to build a microscope, magnifying glass, telescope, and periscope. The sundial can be used to tell time. The model utilizes fiber optics to explain what light transmission is and how light can be used for data transfer. This educational kit gives students an in-depth look at the world of optics and light. The kit can be used in both supervised and unsupervised learning environments and is part of the essential STEM equipment in many schools. The kit is supplied in a sturdy Gratnells box with a protective lid and a specially designed storage system for components in SEPARATE trays. Additional educational material: Innovative educational materials from fischertechnik help teach technical concepts in a hands-on way and familiarize students with them. The educational didactic workbook, which includes tasks with solutions and handouts, also offers demonstration models that help quickly prepare lessons. Key topics: Light refraction, Light reflection, Light and shadow, Fiber optic cable, Optical illusions.
