Missouri DNR Environmental Outreach Program
Missouri DNR's St. Louis Regional Office offers free 40- to 60-minute presentations tailored by grade, from a whole-body Water Cycle Reenactment for grades 2 through 4 to a Safe Drinking Water presentation with a Water Treatment Challenge for grades 9 through 12, each pairing a hands-on activity with core water-science content. The program serves eight eastern Missouri counties; in-person presentations are currently unavailable, and virtual sessions are offered on a limited basis.

Our take
Each presentation is designed for a specific grade range, so a teacher can choose one pitched to their students' level. The St. Louis office notes that in-person presentations are not available at this time and virtual sessions are limited, so confirm what the office can offer before planning a date.
