Solaris

Contents: wooden clock (37 x 31 x 10 cm) with storage compartment for the clock faces 4 interchangeable wooden clock faces in different colours (27 cm Ø) 2 removable wooden clock hands plastic sundial pointer

The Solaris clock turns telling time into a creative activity. Pupils can build their own clock using the Solaris components. It is a unique, multipurpose clock. There are several interchangeable faces; Arabic numerals and Roman numerals, divided into minutes and a sundial. Introducing the concept of time as a function of the sun and the rotation of the earth opens an entirely new perception of time concepts and their relationships to pupils. The supplied compass is needed to orient the clock to North and introduces the concept of direction on the planet’s surface (also known as “magnetic” North).
