Lunar phases control chart - unlabelled

The unlabelled LUNAR PHASES CONTROL CHART is useful for making the work with the interlocking for the study of the moon phases autonomous. In fact, the map can be placed under the interlocking to give the possibility to work autonomously and correct and verify the position of all the moon phases. The map is plastic-coated and is called "mute" because it does not show any names. Working with the control map is useful for sensory knowledge of all the phases of the moon, i.e. the different aspect it shows towards the Earth during its motion, and for self-checking. The work can be implemented by using the other maps, which gradually complete the study.
