Summary of Summary of Sun and Shadow Positions

INTRODUCTION

Discovering the Universe: Studying the positions of the Sun and shadows is like opening a door to the universe.
Natural Clock: The Sun is our natural clock, and understanding its position helps us know the time without looking at a clock!
Day and Night Cycle: By learning about the Sun, we begin to understand the day and night cycle we experience every day.
Orientation and Direction: Knowing the position of the Sun teaches us about directions like North, South, East, West. This was used before we had GPS!

Part of the Whole: We are exploring the world around us in Science. The Sun is a key piece in this giant puzzle.
Seasons of the Year: The position of the Sun is connected to the seasons of the year and the weather we feel.
Everyday Experiences: Everyone notices the Sun and shadows in their lives. Now let's understand why!
Step by Step: After learning about living beings and the human body, now it's time to look up and discover more about what happens in the sky.

Sun: A giant, hot star in the center of our solar system.
- Shines and emits light and heat, essential for life on Earth.
- Apparent movement from East to West, due to the rotation of the Earth.
Earth: Our planet, where we live, and that rotates around its own axis and around the Sun.
- Rotation causes the alternation between day and night.
- Tilt of the axis and movement around the Sun creates the seasons.
Shadow: Dark area created when an object blocks the light.
- Size and direction of the shadow change during the day.
- Shorter shadow at noon; long and inclined shadows in the morning and afternoon.

Rotation: Movement of the Earth spinning around its axis.
- Happens every 24 hours - a full day.
Revolution: Movement of the Earth in its orbit around the Sun.
- Takes about 365 days - a year.
Axis: Imaginary line that passes through the center of the Earth, from pole to pole.
- Inclined in relation to the Sun, causes the seasons.
Sunlight: Light that comes from the Sun and travels through space until it reaches the Earth.
- Source of energy and heat.
Cardinal Directions: North, South, East, West.
- Used for orientation and location.

Lunchtime:
- When the sun is at its peak, meaning right above our heads.
- Shadow is at its shortest, because the sunlight is coming directly from above.
Sunrise and Sunset:
- Sun appears in the East in the morning, gradually illuminating and warming up.
- In the afternoon, the Sun moves to the West and disappears, creating long and inclined shadows.
Shadow Play:
- Game where a shadow is observed in the morning, noon, and afternoon.
- We notice how the shadow changes position and shape throughout the day.

Tracking the Sun: The Sun seems to travel from East to West in the sky. It is the Earth's rotation that makes it appear that the Sun is moving.
Shadow as an Indicator: The shadow can show us the hours of the day. Long in the morning, short at noon, long again in the afternoon.
Effect of Tilt: The tilt of the Earth's axis in relation to the Sun creates the seasons and causes the variation in the Sun's height in the sky.
Day and Night: The Earth's rotation defines the cycle of day and night. When we are facing the Sun, it is day; when we are facing away, it is night.
Observing the Sky: We can learn about the movements of the Earth by looking at the sky. The Sun and the stars guide us in this great cosmic clock.

Sun-Earth Relationship: The position and movement of the Sun we observe are actually due to the Earth's rotation, which occurs constantly.
Changing Shadow: The shadow of a fixed object changes throughout the day, showing the passage of time in a natural and visible way.
Understanding Time: By understanding the movement of the Earth and the sunlight, we can have a new way of seeing time without using clocks.

Draw the Path: Draw a picture divided into three parts. In each part, draw the same object with its shadow at three times of the day: morning, noon, and afternoon. Show how the shadow changes.
Mime the Sun and the Earth: Play a game where one child is the Sun and another is the Earth. The Earth should orbit around the Sun and then rotate around itself. Explain what happens to the position of the Sun and the shadows on Earth.
Sky Diary: Keep a small diary of the sky for a week. Write or draw how the Sun is throughout the day and try to guess the time by the shadows you see. Check with a clock!
