1
Bellringer What is the correct order of the moon phases? Please place them in order in your composition book. 3rd quarter, 1st quarter, new moon, full moon, waxing gibbous, waning gibbous, waxing crescent, waning crescent
2
Objective (Review) Understand the different phases of the lunar cycle.
GLE Describe the different stages in the lunar cycle. With a 90% mastery, students will be able to accurately name and place in the correct order the different stages of the lunar cycle.
3
Let’s Pause and Think… What helped you to learn and remember the phases of the moon from the 4th grade? Any tricks or sayings? Turn and tell a partner some of these ideas. Be ready to share to the class.
4
Before we go any further….
Rotate-To spin or turn. Revolve-To go around. Let’s practice this….Stand up and push your chair in.
5
Since humans have walked the earth, we have stared at the changing moon with wonder. But what really causes the appearance of the moon to change so drastically ? The answer has to do with the position of not just moon but the sun and the earth as well. This is also what causes eclipses and tides. We will be discussing these later, but can you name the eclipses and the tides?
6
Remember that the sun is the center of our solar system and the Earth is revolving around the sun as the year goes by and rotating on its axis. SUN Earth But at the same time, the moon is revolving around the earth and rotating on its own axis.
7
Earth Moon The moon revolves around the earth approximately every 28 days. Its rotation is also approximately 28 days. So the same side of the moon is always facing the earth.
8
Lets Try to Act this Out Find a partner
One person needs to be the Earth, and one person needs to be the moon. The Earth rotates on its axis faster than the moon revolves around it. Keep this in mind.
9
The Moon does not give off its own light but reflects light from the sun. Half of the moon that faces the earth is not always the half that is being lit by the sun. SUN EARTH Moon
10
Lets play a review matching game!
Using the cards, play the matching game to refresh your memory and get you ready for tomorrow’s lesson. Each winner gets a prize so play hard!
11
Summarizer Using what you learned in fourth grade, let’s have a little review to get you ready for tomorrow. Complete the moon phases worksheet. Word bank New moon Waxing gibbous Full moon Waning gibbous Waxing crescent Waning crescent 1st quarter 3rd quarter
12
Bellringer Why does it take roughly 28 days for the moon to complete a lunar cycle? Think about how this relates to your own life and what you experience every 30ish days (think calendar)….
13
Objectives Students will: Understand how the moon moves in space.
Understand what causes the phases of the moon. GLE Explain how the positional relationships among the earth, moon, and sun control the length of the day, lunar cycle, and year. GLE Describe the different stages in the lunar cycle. With a 90% mastery, students will be able to accurately draw a diagram of a full moon and write a paragraph explaining the positional relationships of the sun, moon and earth during this phase.
14
Think So we know that the same side of the moon always faces the Earth…. But why does the shape of the moon look different every night? Turn and tell your neighbor.
15
Lets Take a Poll What causes the phases of the moon?
The Earth’s shadow on the moon. How much of the sunlit side of the moon faces the Earth Clouds blocking the moon’s light
16
What causes the phases of the moon?
Phases of the moon are caused by how much of the sunlit side of the Moon faces the Earth.
17
When it is darkest, men see the stars.
- Ralph Waldo Emerson
18
First Quarter Moon Waxing Gibbeous Waxing Crescent Full Moon New Moon
Gibbous means to be humpbacked Waxing means to grow Waxing Gibbeous Waxing Crescent In between each of the quarter phases are other distinct phases. Full Moon New Moon Waning Crescent Waning Gibbous Waning means to decrease Third Quarter Moon
19
Draw something similar to this in your comp book for each moon phase
Draw something similar to this in your comp book for each moon phase. We will fill it out as we go. You will need 8 circles total for all 8 moon phases. ________________________________________________________________________ ____________________________________
20
NEW MOON The light from the sun is hitting the side of the moon facing away from the Earth. SUN EARTH
21
Open Ended Question During a new moon phase, why don’t we see the moon at all? Use your white board. Be ready to discuss
22
Waxing crescent The moon can now be seen from Earth. The lighted side we see from Earth is on the right, however it is only a small sliver of light.
23
We’re half way…Let’s think
What moon phases have we discussed so far? Turn and tell your partner about some of these moon phases. Be ready to share with the class.
24
FIRST QUARTER MOON SUN EARTH
Approximately one week later, we see half of the lighted side of the moon. This is called a first quarter moon. SUN EARTH
25
Waxing Gibbous The lighted side we see from the Earth continues to grow. The right side of the moon is visible from Earth.
26
Lets Think about the Poll (REASONING)
What causes the phases of the moon? The Earth’s shadow on the moon. How much of the sunlit side of the moon faces the Earth Clouds blocking the moon’s light
27
Summarizer-Draw it-Diagram the sun, moon, and earth during a moon phase of your choice. Make sure to label your drawing and write a paragraph explaining how this lunar phase is formed. Answer the questions on the board too!
28
Nov. 30 Bell Ringer Draw the first 4 phases labeled and in order on your white board. Be ready to share with the class.
29
Objectives Students will: Understand how the moon moves in space.
Understand what causes the phases of the moon. GLE Explain how the positional relationships among the earth, moon, and sun control the length of the day, lunar cycle, and year. GLE Describe the different stages in the lunar cycle. With a 90% mastery, students will be able to accurately draw a diagram of a specific lunar phase and write a paragraph explaining the positional relationships of the sun, moon and earth during this phase.
30
Recap What lunar phases have we learned about so far. Turn and discuss these phases with your table group. Think about positional relationships, and how each phase appears from Earth.
31
We will be filling out the last four moon phases today .
________________________________________________________________________ ____________________________________
32
FULL MOON Two weeks after the new moon, a full moon appears. The entire lighted side of the moon is facing earth. SUN EARTH
33
Waning Gibbous The lighted side of the moon that we see from Earth is getting smaller, it is waning. The lighted part of the moon that we see is now on the left.
34
THIRD QUARTER MOON EARTH SUN
Three weeks after the new moon, a third quarter moon appears. We can see half of the lighted surface of the moon from earth. SUN EARTH
35
Waning Crescent The lighted side of the moon that we see from Earth continues to decrease. Now we can only see a crescent of light on the left side of the moon.
36
Four weeks after the new moon, another new moon appears and the cycle starts again.
37
Let’s play a guessing game
You need to divide up into groups of 5. You will take turns. 3 students will have a part. The remaining two students will be the guessers.
38
Summarizer In groups of 3, create a sun, moon, and earth rotation. Go through each of the moon phases to determine the positional relationships. Once you have finished, take out a blank sheet of paper and write about what you models. How does this influence the way we see the moon from Earth.
40
Dec. 1 Bell Ringer Using your white board and marker, answer the following questions: How are ocean tides affected by the moon? Draw and label the last 4 phases in order on your white board too.
41
Objectives Students will:
Understand how the moon moves in space to create solar and lunar eclipses. Understand how the moon affects the ocean tides. GLE Produce a model to demonstrate how the moon produces tides. GLE Illustrate the relationship between the seasons and the earth-sun system. GLE Describe the causes of lunar and solar eclipses. With a 90% mastery, students will be able to accurately model and describe the positions of the sun, moon, and earth during a solar and lunar eclipse.
42
Quick Review How do moon phases effect the tides?
43
Gravity pulls on the oceans and causes the tides.
The moon affects the oceans. The moon’s pull is called gravity. Gravity pulls on the oceans and causes the tides.
44
Turn and Talk Discuss with your shoulder partner the different tides you have learned about and the positional relationships that cause each individual tide.
45
SPRING TIDE Caused when the earth, moon, and sun are in a straight line The combination of the gravitational pull of the sun and moon cause the ocean of the Earth to Bulge. Spring tides occur during new and full moons. Spring tides have the greatest range between high and low tides. Really high, high tides and really low, low tides. SUN EARTH
46
NEAP TIDE SUN EARTH When the earth, moon, and sun are at a right angle
Occur during first and third quarter moons. Produce the least range between high and low tide. SUN EARTH
47
Review game In groups of three, when I say go, create the correct positional relationship between the sun, moon, and earth for which ever tide name I call out….spring, neap.
48
Let's warm up for the main part of today’s lesson...
Using your white board, tell me what you think an eclipse is.
49
Eclipses The Sun and Moon occasionally line up so that we have an eclipse. These eclipses happen every year To see a solar eclipse, you need to be on a particular part of the Earth Only after phases have been mastered should you try to teach the reason for eclipses; otherwise, students will often assume that the reason for the Moon’s phases is the Earth’s shadow. To understand why we have eclipses, we use the golfballs and blacklights, along with an embroidery hoop to model out the changing intersection of the Moon’s orbit with the ecliptic, as the Earth goes around the Sun.
50
But First
51
Using the graphic organizer, fill in the information
Using the graphic organizer, fill in the information. Just follow me if you get lost.
52
Three types of Lunar Eclipses
Penumbral lunar eclipse—the Moon only passes through the penumbra of Earth’s shadow Partial lunar eclipse—part of the Moon passes through the umbra of Earth’s shadow Total lunar eclipse—the entire Moon passes through the umbra of Earth’s shadow Who on Earth will be able to see a lunar eclipse? Anyone who can see the Moon (anyone who is on the nighttime side of the Earth during the eclipse)
53
SOLAR ECLIPSES Occurs when the moon passes between the Earth and sun, blocking the sunlight from reaching Earth. Three types: Annular, Partial, and Total Only occur during a new moon
55
Let’s play a game In your group, form a solar or lunar eclipse when I call one out. Make sure to stay focused and try not to get the two confused!
56
Summarizer Draw a picture (with color) of the location of the sun, moon, and earth for both a lunar and solar eclipse. Make sure to label your picture. Describe what a lunar and solar eclipse look like from Earth.
57
Dec. 2 Bell Ringer If you have not completed your graphic organizer for Penumbra/Umbra, please do so now. If you have completed it, on your white board draw the positions of a Solar Eclipse and a Lunar Eclipse.
58
Objectives Students will:
Understand the different phases of the lunar cycle. Explain the different phases of the Moon using a model. Standard: GLE Describe the different stages in the lunar cycle. SPI Explain the different phases of the moon using a model of the earth, moon, and sun.
59
Oreo Lab Directions: Do NOT touch the Oreos that are on the desk or any other items on your desk. Let’s look at our Oreo Moon Phases Lab worksheet. Procedures are a must-let’s review what to do.
60
Oreo Lab You may only eat your oreos, when you have been checked off with all items completed. After Oreo making of moons, please complete questions. These must be checked by your teacher. Then complete the diagram on the Lab worksheet. This must be completed/turned in before you leave.
61
Summarizer Once you have turned in your Lab diagram, answer this on your white board: Why do we see the same side of the Moon every night?
