1. Seasons
Moon Phases

2. The tilt of the Earth’s axis
Why do we have seasons?
The tilt of the Earth’s axis

3. When the Southern Hemisphere is receiving the most concentrated sunlight, what season is it in the Northern Hemisphere?
Winter

4. Draw a picture that illustrates winter in the Northern Hemisphere.

5. Earth spinning on its axis (causes day and night)
What is a rotation and how long does it take the Earth to make 1 complete rotation?
Earth spinning on its axis (causes day and night)
1 rotation = 24 hours (1 day)

6. Draw a picture illustrating all 4 seasons with the sun in the middle

7. What season is illustrated in the picture below?
Summer

8. What is a revolution and how long is 1 Earth revolution?
Revolution = Earth moving around the sun
1 Revolution = 1 year (365 days)

9. What could we change to decrease the length of day?
Increase the speed of the Earth’s rotation

10. If the Northern Hemisphere is getting indirect sunlight and the days are shorter, what season is it in the southern Hemisphere?
Summer

11. Draw all 8 phases of the moon in order starting with the New Moon:

12. What does the word waxing mean and draw a picture representing waxing.
Waxing = bigger, brighter (light on the right)

13. What is a spring tide? When does a spring tide occur?
-Tide that has the BIGGEST change in tides
-Occurs at New & Full Moon

14. During a new moon, what is the position of Earth, moon and sun?
The moon is in between the Sun and the Earth

15. Looking at the diagram below, how long does it take to get from point 4 to point3?
3 weeks (21 days)

16. Where is the sun located in the diagram below? How did you know?
By moon #4; the sun goes next to the New Moon

17. Based on the phase of the moon on June 27 (as pictured below), what phase of the moon would be shown on July 3?
Full Moon

18. What causes the changes in the lunar cycle?
The relative position of the moon, sun, and Earth

19. In what shape does Earth orbit the sun??
Ellipse

20. What percent of the Earth is lit up at any time?
50%

21. At what positions are we going to have the biggest change in tidal range?

22. What keeps Earth and the moon in orbit?
Gravity

23. Draw a picture that represents the next 3 phases of the moon:

24. What part of the Earth receives the most direct light from the sun?
Equator

25. Draw a diagram that represents a Spring Tide

26. Position 4 – it’s furthest from the sun
At what position in the diagram below do we have a full moon? How did you know? 1
Sun 4
Earth 2
Position 4 – it’s furthest from the sun 3
