Kit Information

Grade: 3
Type: Life Science
This unit encourages students to examine/understand both aquatic and terrestrial ecological systems and their interdependence upon one another.  Students will have a chance to construct both systems separately.  The aquatic ecosystem will include algae, duckweed, elodea, snails, and guppies.  The terrestrial ecosystem will include grass, mustard, alfalfa, crickets, and isopods. Then the students will connect the two systems creating an even larger ecosystem, ultimately examining the impact of adding one ecosystem to another.  Students will determine activities will precede a classroom conference where students compare and contrast the student-made ecosystems with the Chesapeake Bay watershed.  Students will have an opportunity to role-play as boaters, dairy farmers, water men, and general residents that make up the population involved.  Environmental policies and preservation techniques will become significant topics for discussion.
