Experimental inventions of sun-moving
in different time zones.

The first you need to measure is a rising- and a setting time in your latitude and, if possible, an intensity of the sun at the rising, setting and at the midday. So we'll know about how much energy we get from the sun in this day and on your latitude and how does it change in the day.

The rising- and the setting time you get with help of a watch, so you need the time when the sun is visible on the half (when the center of the sun-disk is placed on the horison-line).

The intensity of the sun is measured with help of a light meter.

If you measure the angle between directions on the north and the sun (at rising and setting), you could compare your future theoretical inventions with experimental observing. The measurements perform with a compas.

After all you need to provide an evaluation of result's-dispersion in measurments, then publish your results in kidlink.
