In this unit second graders explore different habitats (forest, desert, water, rainforest, and wetland) and investigate how different plants and animals survive in each the habitat. Rather than just learning facts about the habitats, students examine come to understand the connection between parts of each habitat and how those connections are crucial for survival. Using the Next Generation Science Standards as a guide, students are challenged to use the information they learn about different habitats to compare how different plants and animals depend on their surroundings and other living things to meet their needs. Students will also be challenged to compare the differences in the kinds of living things that are found in different areas and why those differences exist. This unit builds on the first grade Animals unit, in which students learned about different types of animals and their characteristics, and prepares students for a third grade unit in which they will analyze animal adaptations with regard to animal habitats.

This unit uses the Bobbie Kalman Introducing Habitats series as mentor texts. These texts were chosen because of their clear representations of the different habitats and their accessibility. The texts in this unit support student understanding of key genre features while also allowing multiple opportunities to develop fluency. Over the course of the unit the majority of heavy thinking and analysis should be on students. By the end of the unit, students should have a deeper understanding of key components of informational texts, and students should be able to transfer those understandings to other complex informational texts.

Students will also write daily in response to the text, with a focus on making a correct claim to answer the question. Students will also begin writing longer informational texts in which they synthesize and teach back the content they are learning about the different habitats.

In this unit, second graders learn about insects and the impact insects have on the natural world. Building on what students learned in Unit 1 about habitats, they will explore how different insects rely on the environment, or habitat in which they live, for survival. Through this exploration, students will learn the unique characteristics of insects, how insects can be both beneficial and destructive, and the stages of an insect's life cycle. By the end of the unit, students will have a deeper understanding of and appreciation for the beauty of the insect world.

This unit is comprised of predominantly shared reading experiences to help students practice different reading strategies and skills. Building on unit one, students will continue to be inquisitive, active consumers of texts by asking and answering questions, and they will continue to deepen their understanding of the role text features and illustrations play in helping a reader better understand the content of a text. Students will also begin to explore the connections between scientific ideas and concepts using cause-and-effect language and will continue to strengthen their habits of discussion as they debate and analyze key ideas of the unit.

Learn about the diverse group of wildlife known as water birds -- loons, herons, egrets, ducks, geese, grebes, pelicans, and more -- which makes up 30 families, and, collectively about 800 species. Water birds can be found in the mountains, rivers, marshes, and coastal plains; each adapted to their specific environment. Whether year-round residents or long-distance migrants, many water birds depend on critical wetland habitats. Learn more about this amazing avian wildlife and how we can change our behaviors to help their habitats and populations. UNTAMED looks at the wild and often perilous world of wildlife, as seen through the eyes of the patients of the Wildlife Center of Virginia, a non-profit teaching and research hospital for native wildlife.
