PUT THE SKIES IN YOUR STUDENTS’ EYES

The ASTROCYCLE is a geometric form called a HEXAFLEXAGON* formed by connecting together the two ends of a chain of six TETRAHEDRA. The only tools required are children’s scissors, a straight edge, and paper glue or scotch tape.

OPERATING INSTRUCTIONS

Manipulate the ASTROCYCLE by pushing the bottom points of the Tetrahedra up through the center. As each set of surfaces come into alignment you will be able to identify the Signs of the Zodiac, Stars & Constellations on each Hemisphere, and Planets of the Solar System.
