This document provides teacher notes for an ecosystem engagement activity. It instructs teachers to print pictures of biotic and abiotic specimens from various ecosystems as handouts for students. Students are then asked to silently organize themselves into groups based on whether specimens are biotic or abiotic, and then by ecosystem. The goal is for students to use critical thinking to categorize the specimens and develop their own understanding of biotic, abiotic, and ecosystems. Identification of each specimen is included as notes under each slide.

Ecosystem Engage -- Teacher Notes ºÝºÝߣs 2 ¨C 11 are biotic specimens ºÝºÝߣs 12 ¨C 25 are abiotic specimens ºÝºÝߣs 2 ¨C 6, 12 - 14 are from a salt water ecosystem ºÝºÝߣs 7 ¨C 10 are from a wetland ecosystem ºÝºÝߣs 15 ¨C 25 are from land and wetland ecosystems ºÝºÝߣs 15, 16, 19, 20, 22, 25 are based on fresh water PROCEDURE: Print pictures as handouts (2 or 4 to a page) in color if possible. Cut pictures apart. Laminate. Hand a picture to each student as they enter the room. At your signal, have students get up and without talking form 2 groups for Biotic and Abiotic specimens. Tell them they have 2 minutes to do this. Emphasize that they are to do this without talking. When complete, have students explain their reasoning for joining a particular group. Next, have students form groups based on specimens that belong in the same ecosystem. DO NOT tell them how many ecosystems there are. Give them 3 minutes, and there should be no talking during this exercise as well. When complete, have students explain their reasoning for the groups chosen. Students should now be able to come up with their own definitions of biotic, abiotic, and ecosystems. Identification of each specimen is located as Notes under each slide.
