Introduce children to the characteristics of chemical reactions.
Grades K2. In Changes, students learn about changes of state between solids, liquids, and gases. They investigate freezing, melting, evaporation, and condensation of water. The text also explores the results of mixing different solids, mixing solids with liquids, and how to separate mixtures through sieving, filtration, evaporation, and chromatography methods.
Developed to enhance the teaching of the Science and Technology Concepts™ (STC™) unit, the STC Literacy Series™ Changes 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:
Changes paper version (item #971896) comes as a pack of 8 readers. Changes electronic version (item #971896E32) allows 32 students per year to have access to the text for 60 months.
