In Lesson 3, students continue to study interactions among aquatic plants and animals in the class’ miniecosystem bottle aquarium. The class will design and carry out an experiment to find out how plants and animals in a bottle aquarium interact with each other. The class’ bottle aquarium is referred to throughout the unit and evidence from the experiment is used in the unit’s final lesson.
