Mixtures and Movement Slides
A visual guide for Lesson 4 covering Dalton's Law of Partial Pressures, the mechanics of diffusion and effusion, and the relationship between molecular mass and gas speed (Graham's Law). The deck concludes by revisiting the anchoring phenomenon.
Summit Climber Case Study
An application activity for Dalton's Law of Partial Pressures. Students calculate oxygen partial pressure at various mountain elevations and explain the biological difficulty of breathing at high altitudes using pressure gradients and diffusion principles.
Gas Giants Mastery Review
A summative unit review sheet covering the entire 'Behavior of Gases' unit. Includes conceptual questions on KMT, diffusion/effusion, mathematical practice problems for Combined and Ideal Gas Laws, and an application question regarding regional wind phenomena.
Movement Sorting Challenge
A card sort and graphic organizer activity for Lesson 4, distinguishing between diffusion and effusion. Includes scratch modeling spaces, real-world sorting scenarios, and Graham's Law sentence stems for Think-Pair-Share.
Summit Climber Case Study Updated
An updated application activity for Dalton's Law of Partial Pressures, now featuring 'Stop and Jot' prompts, 'Think-Pair-Share' discussion guides, and sentence stems to support student explanations of diffusion at high altitudes.
