  1. Activity 2.4 Soil Sleuthing Earth and Space Science Your Name Enter Date

  2. Learning Objectives: -characterize a local soil sample. -identify similarities and differences between local soil and Martian soil simulant. Student Objectives: -Analyze a local soil sample. -Compare and contrast local soil samples to Mars soil simulant.

  3. National Standards: Standard A: Science as Inquiry (Strand A.2.b) Standard B: Physical Science (Strand B.1.a) Standard D: Earth and Space Science (Strands D.1.e, D.1.k, D.2.a, D.3.a) Key Concepts: Observation, Compare and Contrast, Soil Composition, Soil Profiles, Interpreting Data, Reaching Conclusions

  4. Correlate with Local Standards

  5. Host Researcher Earth and Space Science Vicky Hamilton, Ph.D. Planetary Geologist University of Hawai’i

  6. What is soil? -On Earth soil is a mixture of weathered rock, mineral fragments, organic matter, water and air. -Soil development is a slow process that depends on underlying rock composition, climate, and other conditions

  7. Why do we study soil on Mars? • Is this Mars?

  8. Student Host Mitchell Graves in Death Valley, California

  9. Let’s examine our soil sample -Safety -Tools -Observations -Data Table (SAB page 79 Activity Master 2.4A)

  10. Earth and Mars Soil Comparison • Examine the soil samples and record your data

  11. Observation Questions 1. What were some of the similarities? 2. What were some of the differences? 3. Did you see any signs of life in the soil samples?

  12. Conclusions What were some possible reasons that none of the local soil samples looked exactly alike? 2. Which one did you think was Martian Soil Simulant? How could you test your hypothesis? 3. What have you learned to help answer the big question? How does soil on Earth compare to soil on Mars?
