Hands-On Soil Classification Without AI Tools

Example developed based on CLOs from: CEM 372 – Soil Mechanics.

Purpose

This assignment challenges students to classify soil samples manually, emphasizing hands-on learning and critical analysis. Students engage deeply with soil mechanics principles through observation, testing, and evaluation, fostering practical problem-solving skills applicable to engineering contexts.

This is a human-centric assignment as it requires students to analyze and interpret physical data without reliance on automated tools. By emphasizing manual observation and critical thinking, students develop a nuanced understanding of soil properties and their implications for real-world applications. This approach highlights the uniquely human ability to synthesize information from tactile, visual, and contextual clues, building foundational skills for engineering practice.

Learning Outcomes

• Classify soil samples based on physical and mechanical properties.
• Analyze soil behavior through hands-on testing and observation.
• Reflect on the challenges and insights gained through manual soil classification.

Instructions

Format (Final Deliverable)

1. Soil Classification
   • Collect or receive soil samples for testing.
   • Conduct manual classification based on physical properties (e.g., texture, grain size, moisture content).
   • Record your observations and classify each sample using standard soil classification systems
2. Reporting
   • Write a 500-word lab report documenting your classification process and results.
   • Include diagrams or photos of the soil samples to support your classifications.
3. Reflection
   • Write a 200-word reflection addressing:
     • Challenges faced during manual classification.
     • Insights gained about soil behavior and its implications for engineering.
     • The value of hands-on learning in understanding soil mechanics.
