Dr Dirt’s K-12 Soil Science Outreach
and SO much more
Soil is the foundation of all terrestrial ecosystems and because it is always underfoot, it is often overlooked and nearly always underappreciated.
Soil Science is STEAM!
Dr. Dirt has a passion for telling others about Soil and has been developing simple activities to demonstrate the importance for more than 25 years.

The Soil Science Society of America has a K-12 Outreach Committee that has been developing materials for kids and teachers since about 2005 and has written a book for Middle School and one for advanced high school environmental science/introductory college soils courses. You can find these materials here:
Soil! Get the Inside Scoop Get kids excited about the living world of soil! Written for children aged 9-12, this 36-page, full-color book explores how soil is part of our life – the food we eat, the air we breathe, the water we drink, the houses we live in, and more. The second edition will be published later this year (2025).
Know Soil, Know Life For high school and introductory college students, gain a foundation about the world of soils.
What about the story of that aggregate? It is an aggregate from a poorly drained soil: the gray areas represent an anaerobic (reducing) environment, the black is topsoil transported down by a crawdad, and the orange surrounding it is from the aerobic (oxidizing) environment created as oxygen followed the crawdad burrow.
