Adsorption, not absorption, is when atoms stick to the surface of an object, like water sticking to a grain of sand. An informative lesson delves into adsorption, teaching physical and chemisorption and the factors that affect them. Individuals further analyze Freundlich adsorption isotherms mathematically and finish by exploring catalysts and their roles in chemical reactions.

Instructional Ideas

• Make copies of the lesson for classes, and as teachers are direct teaching, have pupils write down their questions in the notes portions; after teaching a chunk of the lesson, address all questions

Classroom Considerations

• Concepts definitely fit best with higher-level chemistry classes
• No materials or tools are necessary for this lesson

Pros

• Lesson includes an assessment, called a terminal exercise, which is 20 questions
• In-text questions embedded throughout lesson help determine if classes are mastering concepts; lesson includes a key for these

Cons

• None
