Soils and Worms

As part of our Soil study, we investigated worms.  Students had the opportunity to touch and observe a worm.  Then we placed them in a controlled environment.  We watched over weeks to see how the worms decomposed the leaves and changed the soil... When we "released" the worms months later...the container was empty.  We discovered some rich black soil and concluded that our worms decomposed themselves.





Some students LOVED the worms...




Others were not so sure...
