**Lesson Plan: Basic Science and Technology - Types of Soil**
**Grade Level:** Primary 1
**Subject:** Basic Science and Technology
**Topic:** Types of Soil
**Duration:** 45 minutes
---
**Objective:**
By the end of this lesson, students will be able to:
1. Identify three different types of soil (sandy soil, clay soil, and loamy soil).
2. Describe the basic characteristics of each type of soil.
3. Recognize the uses of different types of soil.
---
**Materials Needed:**
1. Samples of sandy soil, clay soil, and loamy soil in clear containers.
2. Magnifying glasses.
3. Small shovels or spoons.
4. Water in spray bottles.
5. White paper or trays for each type of soil sample.
6. Chart paper and markers.
7. Visual aids or slides showing gardens, farms, and construction sites.
8. Worksheets for soil identification and characteristics.

**Procedure:**
**Introduction (10 minutes):**
1. **Greeting and Warm-Up:** Start with a greeting and a simple question to spark interest in the topic. Example: "Have any of you ever played in the garden or made mud pies?"
2. **Objective:** Explain to students that they will learn about different types of soil and their uses.
3. **Engagement:** Show pictures of various places like gardens, farms, and construction sites and briefly discuss what they have in common (soil).
**Direct Instruction (15 minutes):**
1. **Visual and Explanation:** Show students the three types of soil samples. Label each one and discuss:
- **Sandy Soil:** Explain that it feels gritty and has large particles. It doesn’t hold water well.
- **Clay Soil:** Point out that it feels smooth and sticky when wet, and has very small particles. It holds water well.
- **Loamy Soil:** Describe it as a mix of sand, silt, and clay, feeling soft and crumbly. It holds water but also drains well.
2. **Characteristics and Uses Chart:** Create a simple chart on chart paper listing characteristics and uses of sandy, clay, and loamy soil.
**Guided Practice (10 minutes):**
1. **Observation Activity:** Split the class into small groups. Give each group samples of the three types of soil along with magnifying glasses, small shovels, spoons, water sprays, and trays.
2. **Exploration:** Ask students to feel, look at, and add a little water to each soil type. Let them note the differences.
3. **Discussion:** Reconvene and discuss their observations. Encourage sharing of thoughts and findings.
**Independent Practice (5 minutes):**
1. **Worksheet Activity:** Distribute worksheets where students will match each type of soil to its characteristics and uses. For example: "Feels gritty and doesn't hold water well" (match with Sandy Soil).
**Conclusion (5 minutes):**
1. **Review:** Summarize the main points covered in the lesson: the types of soil, their characteristics, and uses.
2. **Question Time:** Allow students to ask any questions they might have.
3. **Homework Assignment:** Ask students to collect a small soil sample from their home or nearby garden and describe its characteristics with the help of their parents.
**Assessment:**
1. **Informal Assessment:** Observe students during group activities for participation and understanding.
2. **Worksheet:** Review completed worksheets for accuracy.
3. **Class Discussion:** Gauge comprehension through students' responses and participation in discussions.
**Extension:**
1. **Soil Art:** Students can create simple art using soil samples.
2. **Planting Activity:** Begin a small class garden project where students can apply their knowledge about soil.

**Note:** Ensure that all soil samples are safe and free from contaminants before allowing children to handle them, and supervise all activities closely.
