**Lesson Plan: The Earth in Space II**
**Subject:** Basic Science and Technology
**Grade:** Junior Secondary 1
**Duration:** 60 minutes
**Topic:** The Earth in Space II
---
### **Objectives:**
By the end of this lesson, students should be able to:
1. Explain the Earth's position and movement in space.
2. Describe the rotation and revolution of the Earth.
3. Understand the impact of the Earth's movements on day and night, and seasons.
4. Identify the phases of the moon and their effects on Earth.
### **Materials Needed:**
- Globe
- Flashlight
- Interactive whiteboard or chalkboard
- Diagrams showing the Earth's rotation and revolution
### **Lesson Outline:**
#### **Introduction (10 minutes)**
1. **Review Previous Lesson (5 minutes):**
- Briefly review what was covered in "The Earth in Space I."
- Ask students questions to assess their understanding (e.g., What is the solar system? Name the planets.).
2. **Set the Scene (5 minutes):**
- Introduce the topic by explaining that today we will further explore Earth's movements in space.
- Share and discuss the objectives of the lesson with students.
#### **Development (30 minutes)**
1. **The Earth's Rotation (10 minutes):**
- Explain that the Earth rotates on its axis, which takes approximately 24 hours and results in day and night.
- Use the globe and flashlight demonstration to show how different parts of the Earth experience daylight and darkness.
- Engage students by asking them to predict what happens to daylight in different positions on the globe.
2. **The Earth's Revolution (10 minutes):**
- Describe how the Earth revolves around the Sun, taking approximately 365.25 days to complete one orbit, leading to a year.
- Use the globe to show Earth's tilt and its elliptical orbit around the Sun.
- Explain the significance of the tilt in the Earth's axis and how it causes different seasons.
3. **Phases of the Moon (10 minutes):**
- Introduce the concept of the Moon's phases and how it changes as it orbits the Earth.
- Show diagrams or animations of the Moon’s phases (New Moon, First Quarter, Full Moon, Last Quarter).
- Explain the impact of the Moon's phases on tides and some cultural events (e.g., Lunar New Year).
#### **Activity (15 minutes)**
1. **Hands-On Demonstration:**
- Divide students into small groups and provide them with globes and flashlights.
- Ask each group to demonstrate the Earth's rotation and how it causes day and night.
- Have students depict the Earth's revolution around the Sun using a designated “Sun” spot in the classroom and rotating the globe.
2. **Moon Phases Matching Game:**
- Provide students with pictures of different moon phases and names.
- Instruct students to match the pictures with their corresponding names.
#### **Conclusion (5 minutes)**
1. **Recap Key Points:**
- Quickly review the main concepts discussed: Earth's rotation, revolution, and Moon phases.
- Highlight the importance of these movements and their effects on life on Earth.
2. **Questions and Answers:**
- Allow a few minutes for students to ask any questions they may have.
- Provide answers and clarifications as needed.
#### **Assessment:**
- Formative: Observation during hands-on activities and group participation.
- Summative: A short quiz on the next class (or as homework) covering the Earth's rotation, revolution, and Moon phases.
### **Homework/Extended Activities:**
- **Homework:** Assign a worksheet with questions on the topics covered.
- **Extended Activity:** Suggest students keep a Moon journal for a month, noting the phases they observe each night.

### **Additional Notes:**
- Ensure that the lesson is inclusive and accommodates all learning styles by using visual, auditory, and kinesthetic teaching methods.
- Encourage students to relate what they have learned to real-life observations, such as the changing seasons and moon phases they can see.
