Roughly 4.5 billion years ago, Earth began to form as a result of matter clumping together due to gravitational attraction. Over time, these clumps of matter started crashing into each other, forming larger bodies that eventually would lead to planets and moons. The following activities will introduce students to the phases of the moon and how the orbit of the Moon affects life on Earth!
What causes seasons to change? Seasons are caused by direct light on a hemisphere, or indirect light!

The Sun's rays that hit the Northern Hemisphere are spread around over a large area. The Sun's rays that hit the Southern Hemisphere are concentrated over a smaller area. Where the Sun's rays are more concentrated, there are hotter average temperatures.
