Introduction (10 - 12 minutes)

1. Recap of Previous Knowledge: The teacher begins the lesson by recalling the basic knowledge of the Solar System and the position of Earth within it. This includes a brief review of the Sun being the center of our Solar System, with the Earth as the third planet from the Sun. The teacher also reminds students about the concept of day and night, which they should already be familiar with.

2. Problematic Situations and Questions: The teacher then presents two problem situations related to the topic:

   • "Why do we have different seasons? And why are the lengths of day and night not equal throughout the year?"
   • "Have you ever wondered why the position of the Sun in the sky changes throughout the day and throughout the year?" These questions are designed to pique students' curiosity and to serve as a starting point for the development of the lesson.

3. Real-world Contextualization: The teacher emphasizes the importance of understanding Earth's movements by explaining how these phenomena affect our daily lives. For example, the changing seasons influence our clothing choices and the types of food we eat, while the rotation of the Earth determines the length of our day and night.

4. Introduction of the Topic: The teacher introduces the topic of the day's lesson, Earth's Movements, by sharing two interesting facts:

   • "Did you know that the Earth rotates on its axis at a speed of around 1,000 miles per hour, but we can't feel it because we're also moving with it?"
   • "The Earth is not perfectly upright in its orbit. It's tilted at an angle of about 23.5 degrees. This tilt is what gives us our seasons." These facts are intended to capture students' attention and spark their interest in the topic.

5. Curiosities: The teacher then shares two more curious facts related to the topic:

   • "The Earth's rotation is gradually slowing down. In about 140 million years, a day on Earth will be 25 hours long instead of 24!"
   • "Although the Earth's orbit around the Sun is not perfectly circular, it's actually an oval shape called an ellipse. This means that our distance from the Sun changes throughout the year." These curiosities should further engage students and make them eager to learn more about Earth's Movements.

Development (20 - 25 minutes)

1. Theory and Conceptualization of Earth's Movements (7 - 10 minutes):

   • Rotation of the Earth: The teacher explains the concept of the Earth’s rotation on its axis, describing how it takes approximately 24 hours, resulting in the alternation of day and night. A visual aid, such as a globe or a diagram, can be used to illustrate this concept. The teacher can also emphasize that the Earth's rotation is responsible for the perception of the Sun's apparent movement across the sky.

   • Revolution of the Earth around the Sun: The teacher then transitions into the concept of the Earth's revolution around the Sun, explaining that it takes about 365.25 days or one year to complete. An illustration of the Earth's orbit around the Sun can help students visualize this phenomenon. The teacher can also clarify that this movement is responsible for the changing of seasons.

   • Tilt of the Earth's Axis: The teacher continues by discussing the tilt of the Earth’s axis, explaining how it causes the varying lengths of day and night throughout the year. The teacher should emphasize that this tilt is also responsible for the occurrence of the different seasons. A diagram displaying the Earth's tilt at various points in its orbit can aid students' understanding.

2. The Role of Gravity (5 - 7 minutes):

   • Gravity and the Earth's Orbit: The teacher then introduces the concept of gravity and its role in the Earth's movements. The teacher can use the example of a tetherball or a pendulum to illustrate how gravity keeps the Earth in its orbit around the Sun.

   • Gravity and the Earth's Rotation: The teacher also explains that gravity affects the Earth's rotation, slowing it down ever so slightly over time, which is why we have to add a leap second to our clocks every few years.

   • Gravity and the Tilt of the Earth's Axis: The teacher can then mention that gravity is responsible for the Earth's tilt, as it keeps the Earth from wobbling too much. A visual aid, such as a spinning top, can help illustrate this point.

3. Effects of Earth's Movements (8 - 10 minutes):

   • Changing Position of the Sun: The teacher explains how the Earth's movements affect the apparent position of the Sun in the sky. When the Earth is tilted towards the Sun, it is summer in that hemisphere, and the Sun appears higher in the sky and the days are longer. When the Earth is tilted away from the Sun, it is winter, and the Sun appears lower in the sky, and the days are shorter.

   • Different Seasons: The teacher then elaborates on the effects of the Earth's tilt on the occurrence of seasons. The teacher can use a diagram showing the Earth's tilt at various points in its orbit to illustrate this effect.

   • Day and Night: The teacher also explains how the Earth's rotation causes the alternation of day and night. The teacher can use a globe or a light source to demonstrate this phenomenon.

4. Reflection and Discussion (2 - 3 minutes):

   • The teacher then encourages students to reflect on what they have learned and to ask any remaining questions. The teacher can facilitate a brief Q&A session or a small group discussion to ensure that all students have a clear understanding of the topic.

This development phase provides a comprehensive overview of the topic, ensuring that students understand the basic concepts of Earth's movements and appreciate the role of gravity in these movements.
