Pond Life, Second Edition

Classroom aquariums simulate freshwater pond ecosystems in this observation-oriented unit. Students learn how, when, and where to look at organisms interacting with one another and with their environment. Just as important, they develop the ability to interpret what they see. With different magnifying lenses, students study microscopic pond organisms in their aquariums and in a hay infusion. Then, they examine the structure and behavior of several macroscopic organisms, including the food chains that connect them. Separate activities on snails, fish, and duckweed help students identify their adaptive features and responses to environmental stimuli. Finally, they pose an original Pond Life question, propose a hypothesis, and experiment to find the answer. (12 Activities)
