Objectives (5 - 7 minutes)

1. Understand the Concept of Solar System: The students will be able to define and explain the basic concept of the solar system, including its components (sun, planets, moons, asteroids, comets, and meteors) and their relative positions.

2. Identify the Characteristics of Each Component: The students will learn to identify and describe the key features and characteristics of each component of the solar system.

3. Comprehend the Scale and Size of the Solar System: The students will develop a sense of the vastness of the solar system, understanding the scale and size of the sun, planets, and other celestial bodies in relation to Earth.

Secondary Objectives:

1. Encourage Active Participation and Collaboration: The lesson aims to foster an interactive learning environment where students actively participate in discussions, share their ideas, and collaborate with their peers.

2. Promote Curiosity and Interest in Outer Space: The teacher will strive to spark the students' curiosity and interest in the subject matter, encouraging them to ask questions and explore further on their own.

Introduction (8 -10 minutes)

1. Recall of Previous Knowledge: The teacher will begin by asking a few questions to assess the students' prior knowledge about space and the universe. These questions could include: What is the universe? What is a galaxy? Can you name any other galaxy apart from the Milky Way? If the previous lesson was about stars, the teacher can also ask the students to recall the characteristics of stars.

2. Problem Situations: The teacher will then present two problem situations to the students. First, the teacher asks, "What would happen if there was no sun in our solar system?" and second, "What would happen if the earth was twice as close to the sun as it is now?" These questions are designed to stimulate the students' thinking about the importance of the sun and the delicate balance in the solar system.

3. Real-World Contextualization: The teacher will then contextualize the importance of studying the solar system by explaining its relevance in our daily lives. For example, the teacher can discuss how the sun's energy powers our planet, how the moon affects the tides, and how the understanding of the solar system can help in future space exploration and colonization.

4. Topic Introduction: The teacher will introduce the topic of the solar system by sharing two interesting facts. First, the teacher can explain that the sun is so large that it could fit 1.3 million Earths inside it. Second, the teacher can share that the biggest planet in the solar system, Jupiter, is more than 11 times the diameter of Earth and has a storm that has been raging for over 300 years, known as the Great Red Spot. These facts are intended to grab the students' attention and pique their curiosity about the solar system.

5. Visual Aids: To complement the introduction, the teacher will use a visual aid such as a poster or a digital presentation that displays the planets in the solar system, their relative sizes, and their position in the solar system. This will help the students visualize the topic and make it more engaging.

Development (20 - 25 minutes)

Activity 1: The Solar System Walk (10 - 12 minutes)

1. Preparation: The teacher will have previously marked the positions of the planets and the Sun on the school premises. The positions should be spaced out, maintaining a scaled-down distance between them based on the actual proportion of their distance in the solar system. For instance, if the sun is marked at the entrance of the school, the position of the first planet (Mercury) would be approximately 58 meters away, followed by Venus at approximately 108 meters, and so on.

2. Grouping: The students will be divided into small groups, with each group starting from a different planet's position. Each group will be given a set of task cards containing information about the planet they start from, as well as the next planet to visit.

3. Activity Description: The aim of the activity is for each group to walk the path of the solar system, stopping at each planet, reading the information on the task cards, and then moving on to the next planet. This way, the students will be able to visualize the scale and distance of the solar system.

4. Additional Step: The teacher can make this activity more fun and engaging by asking the students to act out the characteristics of the planets they visit. For example, when stopping at Jupiter, the students could pretend to be as large as Jupiter, or when at Mars, they could imitate the red color of the planet.

Activity 2: The Edible Solar System (10 - 12 minutes)

1. Preparation: Before the class, the teacher will prepare a variety of edible items (e.g., fruits, candies, cookies) that represent the planets based on their size, color, and characteristics. For example, a small orange could represent the Earth, a red candy could be Mars, and a large melon could be Jupiter.

2. Grouping and Activity Description: The students will be divided into groups, with each group receiving a tray with the edible items representing the solar system. The task is for the groups to arrange the edible items in a way that reflects the real positions of the planets in the solar system. This activity allows the students to demonstrate their understanding of the size and position of the planets in the solar system.

3. Discussion and Conclusion: After the items are arranged, the teacher will lead a whole-class discussion, allowing each group to explain their edible solar system and justify their choices. This discussion will help reinforce the students' understanding of the scale and positions of the planets.

Activity 3: Create Your Own Solar System Model (10 - 12 minutes)

1. Preparation: The teacher will provide the students with various materials such as colored paper, markers, modeling clay, and craft sticks.

2. Grouping and Activity Description: The students will be grouped into teams and tasked with creating a model of the solar system. The models should include the sun, the eight planets, and other celestial bodies such as moons, asteroids, and comets.

3. Additional Step: To ensure that the model is accurate, the groups will need to utilize the information provided by the teacher earlier in the lesson regarding the size and characteristics of each celestial body in the solar system.

The development stage of this lesson is designed to be hands-on, collaborative, and engaging for the students. By participating in these activities, the students will not only understand the composition and scale of the solar system but also develop their teamwork and communication skills.

Feedback (8 - 10 minutes)

1. Group Discussion and Sharing (3 - 4 minutes): The teacher will facilitate a group discussion where each group will have the opportunity to share their solutions or conclusions from the activities. This will be a chance for the students to articulate what they have learned and how they approached the tasks. The teacher will encourage all students to participate and ask questions about other groups' work, fostering a collaborative learning environment.

2. Connecting Activities with Theory (2 - 3 minutes): After all groups have shared their work, the teacher will tie the activities back to the theoretical concepts. The teacher will highlight how the activities helped the students understand the scale and size of the solar system, the characteristics of each component, and their relative positions. For example, the teacher might say, "By walking the solar system, you got a sense of how vast it is. And by creating the edible solar system and the model, you were able to visualize the size and positions of the planets."

3. Reflection (3 - 4 minutes): The teacher will then propose that the students take a moment to reflect on the lesson. The students will be asked to think about the following questions:

   • What was the most important concept you learned today?
   • Which questions do you still have about the solar system?
   • How did the activities help you understand the solar system better?

4. Open Discussion (1 - 2 minutes): After a minute of reflection, the teacher will open the floor for a brief discussion. Students will be invited to share their thoughts and answers to the reflection questions. The teacher will also address any remaining questions or concerns about the solar system.

By the end of the feedback stage, the students should have a clear understanding of the solar system's basic components, their characteristics, and their relative positions. They will also have had the opportunity to apply this knowledge in hands-on, collaborative activities, which will help them remember the information better.

The feedback stage is crucial as it allows the teacher to assess the students' understanding of the topic and the effectiveness of the learning activities. It also provides the students with an opportunity to reflect on their learning, identify their areas of strength and areas for improvement, and ask any lingering questions.
