Understanding Chemical Reactions and Rust Formation

This lesson focuses on explaining how rust forms through chemical reactions. Students use models to visualize atom rearrangement, investigate claims about rust formation, and construct written explanations. The lesson includes a warm-up, hands-on activities with paper models, and a reading task about art preservation. Students revise their writing and respond to questions, completing the lesson with a deeper understanding of chemical reactions and rust formation.
