Each board teaches children through various interesting topics how to function in society, allows them to learn about the world around us. We can have several boards and change them in a simple way, and special frames perfectly hold the board against the wall. Characteristics: - We can have several boards and change them in a simple way, and special frames perfectly hold the board against the wall. - The board can also be used without frames, e.g. on a table or floor - the board explains how we use our eyes to gain knowledge about the world around us, about colors, brightness, or the shape of objects - when a child touches a tree (located on the left) the light will turn on, starting from the lens to the retina of the eye - then the image will be transformed into light signals, which reach the brain and are perceived as sight - in addition to light signals, the child also sees that the tree near the retina is inverted, which allows the child to see how our brain processes the image when the brain reaches the already correctly positioned tree - the pictures at the bottom of the board show the child that human eyes can recognize shapes, colors and brightness - the board also teaches children how to take care of their sense of sight - do not watch much TV, do not put anything in your eye, and wear sunglasses when in the sun, and wear protective glasses when using chemicals - batteries are required to work The toy develops: - motor skills - sensory - eye-hand coordination - imagination - concentration - curiosity
