Objectives
Duration: (10 - 15 minutes)
This stage aims to clearly outline the objectives of the lesson, guiding both the teacher and the students on what will be covered. It ensures everyone is aware of the focus of the content and the skills that will develop during the lesson.
Objectives Utama:
1. Understand that the Earth spins on its own axis, leading to the cycle of day and night.
2. Identify how the Earth's spin affects the sun's position in the sky throughout the day.
3. Observe and describe how shadows vary in both position and size at different times of the day.
Introduction
Duration: (10 - 15 minutes)
The purpose of this stage is to engage students and create a context for the lesson. By making the context relatable to their daily lives, students are more likely to be interested and eager to learn about how and why shadows change during the day.
Did you know?
Did you know that shadows change position and size throughout the day because the Earth is always spinning? This gives the illusion that the sun is 'moving' across the sky, but it's actually the Earth that is rotating! That's why a tree's shadow can be in one spot in the morning and then in a totally different location by the afternoon!
Contextualization
Begin the lesson by explaining to students that the sun's position in the sky changes every day, which also affects how shadows move and change size. Ask if anyone has noticed how the shadow of a tree or building changes length depending on the time of day. Clarify that this happens due to the Earth rotating.
Concepts
Duration: (40 - 45 minutes)
This stage aims to deepen students' understanding of the Earth's rotational movement and its effect on the sun's position and shadows throughout the day. By covering specific topics and providing visual and practical examples, students can grasp these concepts thoroughly. The questions posed will help reinforce learning and check understanding of the material.
Relevant Topics
1. Earth's Rotational Movement: Explain that the Earth spins on its own axis. Use a globe to demonstrate this. Emphasize that this rotation takes about 24 hours to complete, causing the cycle of day and night.
2. Position of the Sun in the Sky: Describe how the sun's position in the sky shifts throughout the day due to the Earth's spinning. Utilize images or diagrams to illustrate the sun's path from sunrise to sunset.
3. Shadow Changes: Discuss how shadows change in size and position during the day. Use practical examples and encourage students to observe the shadows of objects in the classroom or on the school grounds. Clarify that shadows are longer in the morning and late afternoon, while they are shorter at noon when the sun is highest in the sky.
To Reinforce Learning
1. Why do shadows change in position and size throughout the day?
2. What causes day and night on Earth?
3. How does the position of the sun in the sky affect the size of shadows?
Feedback
Duration: (25 - 30 minutes)
This stage helps review and reinforce the knowledge students have gained. Through discussing the posed questions, the teacher can clarify any misunderstandings and solidify key concepts. Encouraging students to reflect and ask additional questions promotes critical thinking and application of their learning.
Diskusi Concepts
1. Explain that shadows vary in position and size throughout the day due to the Earth's rotation. As the Earth spins, the sun's position appears to change, which causes shadows to vary. In the morning, when the sun is lower on the horizon, shadows are longer. At noon, when the sun is positioned higher in the sky, shadows are shorter. By the afternoon, shadows lengthen again as the sun approaches the horizon. 2. Clarify that the transition from day to night on Earth is due to its rotational movement. When one side faces the sun, it experiences daytime; as that same side turns away, it becomes nighttime. 3. Discuss how the sun's position in the sky affects the size of shadows. When the sun is lower in the sky (in the morning and late afternoon), shadows are longer since sunlight strikes from a more angled position. When the sun is overhead (around noon), shadows are shorter because sunlight hits almost directly down.
Engaging Students
1. Why do you think shadows change size throughout the day? Can you share an example you've noticed? 2. How would you explain to a friend why we experience day and night? 3. If you were a scientist studying shadows throughout the day, what patterns would you expect to see? Why? 4. In what ways do you think understanding shadows can be useful in everyday life?
Conclusion
Duration: (10 - 15 minutes)
This stage aims to review and consolidate the main points discussed in the lesson, ensuring students fully understand the material. By highlighting the practical relevance of the topic, students can see how what they learned applies to their daily lives, enhancing the learning experience.
Summary
['The Earth rotates on its own axis, completing a rotation approximately every 24 hours, creating the day-night cycle.', "The sun's position in the sky shifts throughout the day due to the Earth's rotational movement, causing shadows to change in size and position.", 'Shadows are longer in the morning and late afternoon because the sun is lower on the horizon, while at noon, shadows are shorter as the sun is higher in the sky.']
Connection
The lesson linked theory to practice by using visual and practical examples, such as observing the shadows of objects in the classroom or schoolyard. This connected students with how the Earth's rotation influences the sun's position and shadows throughout the day.
Theme Relevance
Understanding how shadows change during the day is important for various activities like knowing the best placement for planting trees or building a house, and even for enjoying outdoor activities like playing in the park. Curiosity about the Earth's movements also sparks a scientific interest and encourages observation of the natural world.
