Earth’s _____________ around the sun takes 365 days.

• rotation

• axis

• adaptation

• revolution

Why does the moon appear to move from east to west in the night sky?

• The revolution of the moon around Earth

• Earth rotates from west to east on its own axis

• The revolution of Earth around the sun

• The moon rotates on its axis

The moon rises and sets every day, like the sun. Imagine that you went outside at 7:00 PM and see the moon in the night sky. The next night you go outside at the exact same time you went out on the first night (7:00). The stars are in almost the same part of the sky as they were the first night, but the moon is not. Why has the moon changed its position from one night to the next?

• The Moon is orbiting Earth

• The night sky is moving east to west over Earth

• The Earth is orbiting the sun once per year

• Earth is moving away from the moon

If other stars are brighter and larger than the sun, why does the sun appear so large?

• The sun is the closest star to Earth

• The sun is the brightest type of star

• The sun reflects light from the brighter stars

• There are no stars bigger than the sun

Which of the following demonstrations would be best to show why the Sun appears to be the brightest star seen from Earth?

• Create and present a model of the solar system using clay

• In a dark room, compare the light from two flashlights from two different distances

• Turn the classroom lights off and on several times to compare brightness

• Using a lamp, compare the light from three different light bulbs by switching them out

Which of the following statements about how Earth moves is true?

• Earth’s tilt affects how much sunlight parts of the Earth receive.

• Earth’s tilt does not affect the seasons.

• Because Earth rotates on its axis, the sun sets in the east.

• Because Earth rotates on its axis, the sun rises in the west.

We know that Earth makes a complete revolution around the sun once every 365 days, following an elliptical (oval) orbit. This means that the distance between the Earth and the Sun changes throughout the year. We also know that the seasons are caused by the fact that the Earth is tilted on its axis. This tilt in Earth's axis does not change during the year.

Look at the image of the Earth's orbit around the Sun. Imagine you live at the place marked by the red spot, in the United States and in the northern hemisphere. Find the label in the diagram that says "winter solstice". Compare the length of the day and the time the sun is in the sky with the picture labeled "summer solstice". Provide an explanation for your answer.

• The day length is shorter because the Northern Hemisphere is tilted away from the sun.

• The day length is shorter because the Earth is at its farthest point in the orbit around the sun.

• The amount of sunlight during the year does not change.

• The length of day for both the summer and winter solstice is the same.

What would happen to the seasons of the world if the Earth’s axis tilted in the opposite direction?

• The only season on Earth would be summer.

• Nothing would change. The same seasons would occur during the same months.

• The seasons would be reversed. The Northern hemisphere would receive the most hours of sunlight and most direct sunlight in December instead of June.

• Winter would be much longer.
