Colored unlabelled lunar phases control chart

The coloured unlabelled lunar phases control chart is useful to make the work with the interlocking for the study of the phases of the moon autonomous, the map, in fact, can be placed under the interlocking to give the possibility to work autonomously and correct and verify the position of all the phases of the moon. The map is plastic-coated and is defined as "mute" because it does not indicate any names; the colour helps to recognise the correspondence of the pieces of the joint. Working with the control map is useful for sensory knowledge of all the phases of the moon, i.e. the different aspects 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.
