Why are the days shorter during the winter solstice?
The hemisphere that is experiencing the winter is tilted away from the sun causing the hemisphere to receive less sunlight and less daylight hours.
Draw a model of the Earth, Moon, and Sun during a New Moon.
Draw a picture of a Spring Tide (include the sun, earth, moon, and the tide like in your interactive notebook).

An object in motion will stay in motion and an object at rest will stay at rest unless and unbalanced force acts on the object.
About how long does it take the Moon to orbit the Earth?
A month
Why are days longer during the summer solstice?
The hemisphere that is experiencing the summer is tilted toward the sun causing the hemisphere to receive more sunlight and longer daylight hours.
