1 Department of Mathematics and Science Big Idea 5 : Earth in Space and Time Grade 4 Fair Game Benchmarks SC.4.E.5.4: Relate that the rotation of Earth (day and night) and apparent movements of the Sun, Moon, and stars are connected. (Annually Assessed) SC.4.E.5.1: Observe that the patterns of stars in the sky stay the same although they appear to shift across the sky nightly, and different stars can be seen in different seasons. (Assessed as SC.4.E.5.4) SC.4.E.5.2: Describe the changes in the observable shape of the moon over the course of about a month. (Assessed as SC.4.E.5.4) SC.4.E.5.3: Recognize that Earth revolves around the Sun in a year and rotates on its axis in a 24-hour day. (Assessed as SC.4.E.5.4) Mary Tweedy, Curriculum Support Specialist Keisha Kidd, Curriculum Support Specialist Dr. Millard Lightburn, Elementary Science Supervisor

2 Grade 4 Big Idea 5: Earth in Space and TimeEarth in Space and Time How are the movements of Earth, the moon and the Sun related? Department of Mathematics and Science

3 Relationship with Earth How is the Earth moving? 1. It turns or rotates spinning on its axis in a 24 hour day. 2. It revolves around the sun. Let’s do the Cycle of Day and Night exploration.Cycle of Day and Night Hands-on Activity Materials: AIMS foldable: It’s Apparent tennis ballskewerthumbtack Now let’s read It’s Apparent and explore. Department of Mathematics and Science

4 Observe the Sun Activity Essential Question: How can I observe the apparent movement of the Sun across the sky? Materials: 5 cm straw, lump of clay, compass, ruler, pencil Procedures: 1. Label the direction words North, South, East and West along the edge of the paper plate. 2. Put a small lump of clay in the center of the plate, and stick the straw upright in the clay. 3. Place this sundial in a sunny spot outside that is exposed to the sun for several hours. 4. Use the compass the identify North and make sure the label North on the sundial is pointing North. 5. Observe the straw’s shadow on the sundial every hour. Department of Mathematics and Science

5 Shadows on Sundial Observations (Data) TimeShadow Length Direction Sun is Pointing (North, South, East, West) Position of Sun in Sky (North, South, East, West) After each hourly observation, record data and then look at another group’s sundial and compare yours to theirs. Record Group ____ Then answer: How does your shadow compare to another group’s shadow on their sundial?

6 Shadows on Sundial Connected Learning: 1.How does the position of the shadow change during the day? 2.How would you describe the Sun’s apparent movement in the sky? 3.What is the general relationship between the Sun’s position in the sky, and the direction of a shadow on Earth? 4.How can you use Earth’s rotation to explain shadow movement? TimeShadow Length Direction Sun is Pointing (North, South, East, West) Position of Sun in Sky (North, South, East, West)

7 Let’s look again at the Movement of the Earth Movement of the Earth Department of Mathematics and Science

8 What are Stars? Stars are huge balls of burning gas that give off light. Stars are very bright. Stars come in different sizes. Our Sun is our nearest star. All the other stars we see are very far away. More on Stars There are more than 300 billion stars in the Milky Way. Department of Mathematics and Science

9 Watching the Night Sky Do the patterns of stars or constellations in the sky stay the same?patterns of stars Do we always see the same patterns or constellations of stars nightly? Let’s explore Constellations.Constellations What did you learn? The patterns or constellation stay the same but are seen in different places in the night sky throughout the night and in different seasons. Department of Mathematics and Science

10 Musical Stars Musical Stars Activity Look at the four star chart handouts that you have been given depicting the star patterns or constellations in each of the four seasons. Each group member should stand facing south holding a star chart over their head in the order of the seasons. Work together to determine in what direction the stars move relative to you on the ground and to each other as time and seasons pass. Explain your answer and tell how you got it. Department of Mathematics and Science

11 What do you know? 1. What is a constellation? Answer: A constellation is a group of stars that forms a pattern or image 2. Why do stars appear to move across the night sky? Answer: The stars appear to move because of Earth’s rotation. Constellations or patterns of stars also change with the seasons because Earth is orbiting around the sun. 3. Why do constellations change with the seasons? Answer: The constellations have been in the same positions for thousands of years. As Earth orbits the sun, it goes through different areas of space. This means that each season Earth is in a different part of space. For this reason, the constellations that can be seen from Earth change with the seasons. Department of Mathematics and Science

12 What do we call scientists who study space? Astronomers What tools do astronomers use? Telescopes How Do Telescopes Help Scientists? Telescopes make d i stant objects in space look much closer. Department of Mathematics and Science

13 Up in the Sky The planets and their moons and the Sun up in the sky Make up our solar system stretching far and wide. The Earth and the other planets all spin around the Sun. What spins around the Earth and can be seen by everyone? Round and round the Earth spins a moon that’s all our own.moon With mountains and craters that are hard as stone. The moon seems to change from full to very thin. Did you notice it last night? Did it look just like a grin? Department of Mathematics and Science The Moon

14 Phases of the Moon Department of Mathematics and Science

15 Lunar Looking ActivitiesLunar Looking Essential Question: What changes do we observe in the appearance of the moon each month. Objective: Identify the phases of moon and the current phase. Sequence the main four phases of the moon in correct order. Activities: Explore Gizmos: Phases of the Moon orPhases of the Moon Cycles in the Sky: Moon Phases and/orMoon Phases AIMS Gr. 4 Earth Science: Lunar Looking Read AIMS Phase Facts: The Moon. Department of Mathematics and Science

16 Current Phase of the Moon Resources phase.html phase.html Phases of the Moon Department of Mathematics and Science

17 Lunar Looking Connected Learning 1.How does the moon look when it is full? 2.Which moon phase would apply to use today? 3.Do you always see the moon at night? Explain 4.Have you ever seen the moon during the day? 5.How can you tell the difference between a first quarter moon and a last quarter moon? 6.What other things in the sky occur in a sequence or cycle? 7. What are you wondering now? Department of Mathematics and Science

18 Moon Phase Quiz 1.New Moon 2. First Quarter 3. Full Moon 4. Third Quarter A. B. C. D. Department of Mathematics and Science

19 What Did You Learn? TAG Reflection: Tell a fact you learned about Earth, the moon and/ or the sun. Ask a question about something you don’t understand about Earth in space? Give another idea that you learned in our study of the Earth, moon, and the sun. Department of Mathematics and Science
