It can be a struggle for early childhood teachers to create hands-on, engaging lessons about animals. This is especially true of units that require exposure to a wide range of animals from a variety of habitats. The authors' describe how they shook up their traditional animal unit by creating a Kindergarten zoo! Herein they summarize their "There's a zoo in our room" unit. This unit sequences critical concepts needed to build understanding of core life science ideas as well as science and engineering practices. Students sort and classify animals based on physical characteristics, they speak and write about animals, draw animals, read grade-appropriate text, and use media to obtain the information needed to create a physical replica of a zoo.
