Tellurium – Nienhuis Montessori
The Nienhuis Montessori Tellurium is an attractive and captivating enrichment material representing a simplified reproduction of the solar system. Part of the cosmic education curriculum, the Tellurium model is used for demonstrating the movement of the earth and the moon around the sun.
Derived from the Latin name ‘tellus’ , which means earth, the Tellurium is not a replica of reality, but a model to explain the different principles of day and night, the seasons and the positions of the moon. Tellurium is a visual aid for the child to observe the fascinating effects created by the rotational movements in our sun-earth-moon system.
Working with this material enriches the child’s knowledge about the 3 major rotations:
• The rotation of the earth on its axis each day which signifies day and night: during the day we see the sun, and during the night we see the moon and stars moving across the sky.
• The revolving of the around the earth approximately every four weeks: which signifies the different phases of the moon.
• The revolving of the earth (with the moon) around the sun in one year: this is how we have seasons and a deeper insight into why we can see other constellations.
A flashlight, or ‘sunlight’ can be projected on the earth and the moon to demonstrate the different effects as the earth and the moon revolve. The Tellurium set includes a doll figure that can be affixed with adhesive buddies on the globe to make it easier for the children to place themselves in the situation. An instruction manual that gives further guidance on how to use the Tellurium is also included.
This material is suitable for children aged 6 years and up.
