Background For Teachers:
Intended Learning Outcomes:
The instructor should invite students to observe. The instructor will wet down individual paper towels to the point of being wet but not dripping. Once done, place one paper towel on a cookie sheet out flat, a second paper towel, roll-up a second lengthwise and paper clip to keep it rolled and place it on cookie sheet. Place the last paper towel between two sheets of wax paper, roll lengthwise and paper clip each end to keep rolled. Ask students to make a journal entry prediction. How will the passing of time affect each towel? Entries could be based in 30 minute, one hour, and 24 hour increments for each towel. When time has lapsed, ask: “What has happened to the moisture in each paper towel over time? Can this same change be applied to a living organism? What might happen if these samples were outside?”
Construct a Berlese funnel to be used in the classroom. The purpose of the funnel is to make available a small environment that can be heated and allow the students to observe what effect the heat has on organisms living in the soil, if any.

Science can be a method for enabling students to interpret the world around them. Students should ask questions, make predictions, test and retest, make observations, construct events, and then attempt to communicate this information to another person or write it down. This article refers to patterns that are observable. Students will make journal entries about changes, over time, and how those changes have an effect on a living thing in an environment.
