When Clean SoIL founder Dr. Glenn Poshard first pitched the idea of using education to create a litter free southern Illinois, the Clean SoIL curriculum writers could not help but take that idea and run with it. Below, southern Illinois educators will find lessons that are well on their way to helping achieve that goal.
Each lesson uses the 5E Inquiry Model and leverages experiential education practices to create student driven discoveries in the classroom.
Teachers can also utilize the additional resources page to find extension activities, field trips and funding opportunities for their classroom.
Available Lessons
K-2 Grade Band
It's never too early to get kids involved in science!
With that in mind, the Clean SoIL curriculum writers sought to make fun and engaging lessons designed for younger students in the southern Illinois area. Each lesson details general content knowledge for the instructor, provides a list of resources required for the lesson and contains step-by-step instructions to help excite young minds!
3-5 Grade Band
Lessons for upper elementary students take an interdisciplinary approach. Standards for science, social studies, art, literacy and more were taken into consideration to create what can be found below.
Each lesson details general content knowledge for the instructor, provides a list of resources required for the lesson and contains step-by-step instructions to drive student discovery!

Coming Soon: Curriculum Kits
Don't have all the materials to make a Clean SoIL lesson happen? No problem!
The Clean SoIL curriculum writers recognize that classroom teachers often have to purchase materials for their class out-of-pocket. To make it easier for classroom teachers to implement Clean SoIL lessons, we've secured grant funding to create kits with materials needed for making lessons happen.
