2. Discovering Ecosystems Activity In pairs, place your view finder in the grass. Classify all the things you observe by recording each item in the chart as living or nonliving column. Use a hand lens to look for tiny things in this area. Locate a partner nearby and read your lists to each other.

Discuss with each other how this environment provides for the needs of some of the living things each of you observed.
