Gizmo
Our science class had to do a Gizmo about how the seasons changed and why. The Earth is tilted on an axis that revolves around the sun counter clockwise. The longest day of the year is June 21. Since it's the longest day of the year, the earth is heated longer by the sun's rays and makes the temperature rise. The shortest day of the year is December 21, the sun's rays don't heat the earth as long so it's not as warm. When the sun is directly hitting the Northern or Southern Hemisphere it's summer. Unlike when the sun isn't directly hitting the Northern or Southern Hemisphere it's winter. In between the direct sunlight and indirect sunlight are Fall and Spring.
