Description
Grades 3–5. Wherever there is life, there is an ecosystem. Forests, lakes, and deserts are all examples of ecosystems. In Ecosystems, part of the STC Literacy Series™, students investigate this integral concept in earth science to learn what ecosystems are, what threatens them, and what scientists and other people are doing to keep them healthy.
In Ecosystems, students discover that an ecosystem is a distinct area on Earth that contains both living and non-living things.
Grades 3–5. They learn that a healthy ecosystem is in balance—each of its parts depends on the others, and each gives something back to the system. The book's first section explains basic concepts about ecosystems, from a brief ecological vocabulary lesson to information about the interrelationships of animals with the land and plants in their range. One story presents the theory that a global catastrophe led to the extinction of dinosaurs. Other readings discuss threats to Earth's ecosystems and ways people can minimize those threats. The final section of the book relates the stories of 3 environmental pioneers: Henry David Thoreau, John Muir, and Rachel Carson.
Developed to enhance the teaching of the Science and Technology Concepts™ (STC™) unit, the STC Literacy Series™ Ecosystems reader supports inquiry-based science lessons with engaging informational text. The content gives students a natural transition from hands-on investigations, builds background knowledge to reinforce conceptual learning, and lets students apply relevant nonfiction to their own real-world experiences. Questions provided throughout the book encourage critical thinking and allow children to be actively involved in their learning.
Educational studies show that children are more likely to engage in a reading exercise when the literature is related to a recent hands-on activity. This is exactly how the STC Program™ works. Included in every STC-Elementary™ kit, the STC Literacy Series™ helps improve reading comprehension, and supports the following Common Core Standards:
- RI.1-3
- RI.4-6
- RI.7-9
Ecosystems paper version (item #972896) comes as a pack of 8 readers. Ecosystems electronic version (item #972896E32) allows 32 students per year to have access to the text for 60 months.
