Diffusion & Osmosis with Data Analysis

Students explore principles governing diffusion and osmosis. Students perform a dialysis tubing experiment. They obtain core samples of potato in varying concentrations of sugar-water to measure water potential of the potato cells. Data is collected and analyzed by using the Texas Instruments 82 graphing calculator. Students graph results.

Lesson Planet helps me to customize my curriculum to meet the needs of my mostly ESL, international students. I must orient each lesson to as many as 3 different national curricula (since my students return to their home countries after 1-3 years), while remaining true to the Estonian national curriculum (since I teach in an Estonian Gümnaasium). In other words there is no textbook for me in English. I refer to an Estonian-language math text, for instance, and this year would access the Pakistani national curriculum, as well as the Nebraska curriculum, plus Latvian and Lithuanian textbooks, and reconcile them ALL with the Estonian book! THEN thanks to Lesson Planet, I would find introductory sheets explaining and illustrating the terms to be used, plus inductive practice sheets to accompany my hands-on approach (I use less language and more objects to help overcome the language barriers). Thanks to Lesson Planet, for instance, I have learned to use divided-area models to teach the distributive property with 2 colors of base-ten blocks, AND have been able to find worksheets to accompany this lesson, enabling me to effortlessly bridge the gap between the hands-on activities and the algorithms they were modelling.
