Description

The Animals Two by Two Module provides students with firsthand experiences to help them develop an understanding of what animals need to survive and the relationship between their needs and where they live. Appropriate classroom habitats that serve as model systems are established for some organisms, and students provide what the animals need to live and grow. In several investigations, animals are studied in pairs.

• Anchor phenomenon 1—A pond habitat for animals
• Anchor phenomenon 2—Animals living in a compost bin
• Anchor problem 3—A classroom land habitat for animals
• Anchor phenomenon 4—Pencil-sized holes in a tree trunk

Throughout the module, students engage in science and engineering practices by asking questions, planning and carrying out investigations, observing, recording, and interpreting data to build explanations, and obtaining information from photographs. Students use models and engage in argument from evidence. They gain experiences that will contribute to an understanding of the crosscutting concepts of patterns; cause and effect; systems and system models; and structure and function.
