Observing an Aquarium, Third Edition

Your class will build and maintain aquariums that become, over several weeks, diverse underwater ecosystems. Students can observe food chains operate, populations change, and life cycles unfold. One by one, organisms are introduced into freshwater habitats: two types of aquatic plants, tropical fish, pond snails, algae, and tiny crustaceans called daphnia. Students examine each one to discover how it is suited to life under water. By the time they take an end-of-unit field trip to a local pond, they are experienced observers who will recognize meaningful similarities and differences between their classroom aquariums and the natural environment. Kit includes materials for 32 students plus comprehensive step-by-step teacher guide with student activity sheets and 3-part assessment feature.
