1. February 4, Q2-Pg.
Daily Goal: We will model how the Moon appears to change shape, and we will be able to explain why this happens.
Homework: Complete your daily Moon Log,
Science Starter:
Describe what reflection means. What is happening to the light wave when it reflects?
What is a full Moon? Does is always stay full?
Make a hypothesis about why the Moon looks bright at night.

2. This is a rare picture of clouds above Mount Everest.
Why do the clouds look rainbow?
(Hint: Think about our milk and water lab and what we know about Sunsets.)

3. On different days, the Moon looks different
On different days, the Moon looks different. Is it actually changing shape? Why does this happen?

4. Let’s investigate!

5. In your table groups, choose one person to be the Earth
choose one person to be the Sun
choose one person to be the artist
choose one person to be the materials manager (If you are in a group of less than 4, one person can be the artist and the materials manager.)

6. Materials Manager,
Put the Styrofoam sphere on top of your popsicle stick so that it looks like a lollipop.
The sphere is the Moon.

7. Earth
will hold the popsicle stick at arm’s length.

8. Arrange yourself like this diagram
Arrange yourself like this diagram. Your lab partner who is being the Earth will stand in the middle of your group.

9. Your lab partner who is being the Sun will stand with a flashlight directly behind the Earth.

10. The Phases of the Moon
Phases of the Moon - the Moon’s appearance at different times during the month
The Moon looks like it is making different shapes, but it is not. This illusion is created by the position of the Moon, the Earth and the Sun.

11. While you watch this clip, pay close attention to:
the shadow on the Moon
the shape of the Moon
the icon in the left corner that shows where the Moon is compared to the Earth
The Changing Moon

12. Does the Moon produce light?
Non-Luminous
Luminous
Luminous objects create their own light.
Examples:
Stars
Light bulbs
Lit candles
Non-luminous objects do not create their own light.
They reflect light from luminous objects.
Examples:
Glass
Metal
Water

13. Luminous:
Non-Luminous:

14. How would the Moon be classified?
Non-Luminous:
Luminous:

15. Luminosity
The Moon is a non-luminous object. It does not produce light.
The Moon looks bright, because it reflects light from the sun.

16. Which half of the moon will reflect light in this diagram?

17. The side of the Moon that is facing the Sun will reflect light.

18. What will the Moon look like from the Earth if it is in this position?

19. What about from this position?

20. The Moon’s Refection
The side of the Moon that faces the sun will reflect the Sun’s light and appear bright.
What will the side of the Moon that is facing away from the Sun look like?

21. The Phases of the Moon

22. The Phases of the Moon
It takes about a month (approximately 28 days) for the Moon to go through all of its phases and orbit all the way around the Earth.
