Title: Introduction to the Solar System
Grade Level: 4th grade
Objective: - Students will be able to identify and describe the different components of the solar system. - Students will understand the relative sizes and distances of the planets in the solar system. - Students will be able to explain the concept of day and night and the reason for seasons on Earth.
Materials: - Pictures or models of the solar system - Chart paper and markers - Worksheets or handouts with questions about the solar system - Computer or projector for multimedia presentation
Procedure:
- Introduction (10 minutes)

- Highlight the characteristics of each planet, including their size, distance from the sun, and unique features.
- Emphasize the relative sizes and distances of the planets by using visual aids or comparisons.
- Group Activity: Planet Profiles (20 minutes)
- Divide the class into small groups and provide each group with a worksheet or handout containing questions about the solar system.
- In their groups, students will research and complete the worksheet by answering questions about a specific planet.
- Encourage students to use books or reliable online resources to gather information.

- Demonstrate how the rotation of the Earth causes day and night.
- Season Explanation (10 minutes)
- Explain the reason for seasons on Earth by using a globe or a model of the Earth and a flashlight.
- Demonstrate how the tilt of the Earth’s axis affects the amount of sunlight different parts of the Earth receive.
- Conclusion (5 minutes)
- Review the main points covered in the lesson, including the components of the solar system, the relative sizes and distances of the planets, and the reasons for day and night and seasons on Earth.
- Allow students to ask any remaining questions or share any additional information they have learned.
Assessment: - Monitor students’ participation during group activities and discussions. - Review completed worksheets or handouts to assess students’ understanding of the solar system. - Ask students to write a short paragraph summarizing what they have learned about the solar system.
