Students learn what adaptations are and how they enable organisms to survive in specific environments. Students learn how producers and consumers interact in a food chain. By the end of fourth grade, students will develop an understanding of living things and environments.
Students make a bottle aquarium for a pond snail.
Students observe the snail in this habitat and infer that the snail's needs were met. Students will complete Lab Manual pages 11-12 as they do this activity. Students construct an apparatus that allows them to observe how quickly water passes through the leaves of jade and coleus plants. Students observe the cups for evidence of moisture over 5 days. They determine the plant through which water passes more quickly.
