Objective

By the end of this lesson, the student will be able to understand the geological impact of horses on the Earth's surface and ecosystems.

Materials and Prep

• Computer or tablet with internet access
• Pen and paper
• Optional: Access to a local library or horse-related books

Prior knowledge: Basic understanding of Earth's surface and ecosystems.

Activities

1. Research the history of horses and their impact on the Earth's surface. Use reliable online sources or books to gather information.

2. Create a visual representation, such as a poster or infographic, showcasing the geological changes caused by horses. Include information on erosion, soil compaction, and the formation of horse trails.

3. Write a short essay discussing the ecological effects of horses on different ecosystems. Consider their grazing habits, impact on vegetation, and interactions with other animal species.

4. Present your findings and visual representation to a family member or friend, explaining the geological and ecological impacts of horses.

Eighth Grade Talking Points

• "Horses have played a significant role in shaping the Earth's surface throughout history."
• "Their hooves can cause soil erosion, especially in areas with loose or fragile soil."
• "Horses' constant grazing can lead to changes in vegetation composition and density."
• "The compaction of soil caused by horses can affect water infiltration and drainage."
• "Horse trails can form over time due to repeated hoof impacts, altering the landscape."
• "Horses can impact other animal species by competing for food and habitat."
• "Understanding the geological and ecological effects of horses can help us manage their presence in different environments."
