Charter schools usually are run by a board comprised of the teachers in the school and a few of the students' parents. The board makes its own decisions on-site. Unlike other public schools, a charter school does not have to seek approval from the school district or school board before it can take action.
because the earth is tilted on an axis, when its tilted away from the sun, they get no sunlight. In the Winter, the earth's north pole points away from the sun, so it is dark for 6 months. In the summer it points towards the sun, so it is bright for 6 months. The earth tilts back and forth on its axis.
This diagram shows how the tilt of the Earth's axis aligns with incoming sunlight around the winter solstice of the northern hemisphere. Regardless of the time of day (i.e. the Earth's rotation on its axis), the North Pole will be dark, and the South Pole will be illuminated; see also arctic winter.
