CONTENT • About the project • How Sunclock „works”? • What’s „analemma”? • Layout making process? • How to make sunclock using our layout plan? • How to determine „true north”? • Measurements „on the ground” • Finalize your project • Info
TRUE SCHOOL PROJECT • EKOLOGICAL • EDUCATIONAL • FUN • PRACTICAL • UNIQUE • PERMANENT • ACCURATE
How Sunclock works? • Earth around the Sun – changeable movement • „Sun” time = local time on the belonging meridian • „Zone” time = agreement made by man
Analemma – Sun „eight” „Sun movement” on the sky throughout year „Copied” analemma on the date scale
Result of the layout making process „standard time” Measurement point Date scale – standing point depends on time of the year „DST”
How to determine „true North”? • First step when using our layout plan • Determine N-S direction using shadow string string J board S S board J
Measurement point marking N-S axis Y Measurement point E-W axis X
„Ring” elements marking Jedna oznaka Hour marking x x y y
