Soil Formation Factors for High School Earth Science
By Hayden O.
A slideshow for 9th-grade Earth Science that walks students through the five factors of soil formation (time, parent material, climate, biotic factors, and topography), with one slide per factor showing its role in building soil. It reinforces weathering and erosion as a review and aligns with standard ESS.EES.2.4, making it well suited to a single class period.

Teacher Guide & Tips
- Use as a whole-class lesson of roughly 30 to 45 minutes, presenting one factor per slide and pausing to connect each to the weathering and erosion concepts students already know.
- Discussion question: How would soil formed on a steep slope differ from soil formed on a flat plain over the same length of time, and why?
- Scaffold for struggling readers: Provide a one-page table with the five factors in the left column and blank columns for "Effect on soil" and "Example," so students can fill it in as you present.
- Extension for advanced students: Ask them to predict how changing one factor, such as moving the same parent material from a wet tropical climate to a dry desert, would alter the soil profile that forms.
- Estimated time: About 5 minutes of review on weathering, then 3 to 5 minutes per factor, for a total of roughly 25 to 35 minutes including questions.
