The following activities will help you explore how the earth and moon move around the sun.

Activity 1:
Go to the following activity below and then answer the questions below in your science journal.

The Earth's Orbit Activity

1) How many months did it take to get the earth to orbit the sun one time?
2) Describe the motion of the earth and moon as it traveled around the sun?
3) How many hours did it take you to get the earth to rotate once around it's own axis?

Activity 2:
Go to the following websites, watch the videos, and complete the activities. Then answer the questions below in your science journal.

The Moon's Orbit
Video on the Moon's Orbit
Lunar Phases

1) Describe the motion of the moon as it orbits around the earth.
2) Why do we only ever see one side of the moon?
3) Why does the appearance of the moon change as it orbits the earth?
4) What causes eclipses?
5) What causes night and day?

Activity 3:
Now that you know how the earth and moon orbit around the sun that produces different lunar phases lets chart how the moon will look to us this month.

Step 1:Print out the current month from the website below.
Moon Phase Calendar
Step 2: Go to the following website and find out what the moon will look like tonight and record it on your calendar.
Moon Phase Images
Step 3: Predict what you think the moon will look like each night for the rest of the month
Step 4: Check your predictions to the current month's chart located in the Earth Matters box on following website.
Our Moon
Step 5: In your science journal record how your observations on how your predictions of this months lunar phases differ from what the chart says and why do you think they were different.

Activity 4:
Divide into a group of 3-4 students. Using the information from the previous activities and any additional research, complete an online report using our class wiki about you what you learned.
