Earth is ball shaped, rotate on tilted 23.5 degree axis and has elliptical orbit around sun ...just these facts makes earth really interesting place to live on! Amount of sun energy (light) varies throughout year and we have different seasons and then life escapes from being monotones.
Understanding Earth - Sun relations is interesting with some simple day time astronomy experiments. Generally we say Sun is overhead at 12'o clock noon but when we get smallest shadow Sun reaches at zenith and that is different time than our GMT. We get smallest shadow in the north.
On 21st March Sun passes exactly above the equator and reaches line of cancer 23.5 degree N on 21st of June. Then again starts southward journey and reaches equator on 23rd of September. There are certain days twice in these six months that Sun passes exactly above particular place between 0 to 23.5 degree in northen hemisphere. And ....when Sun is exactly above head there is smallest of all solar noon shadows of the year! which seems almost near to 'Zero' or 'No shadow'!
We were waiting for this day since long. If your place's latitude is less than 23.5 Degree then don't miss this amazing phenomena and great opportunity that can inspire your young astronomer!.
