AP Biology Investigation #11 - Transpiration

Experiment kit designed for explaining the mechanics behind nutrient transport in plants Students will test the effect of environmental conditions on bean seedlings, observe the stomatal distribution of a leaf, and even design their own experiment Kit contains enough material for 8 groups, including chemicals, and student exercise copymasters This experiment is designed for use in AP Biology classrooms and coursework, and meets AP Science Practices 1, 2, 4, 6, and 7, as well as Big Idea 4 Safety data sheets included to inform safe storage and maintenance of chemicals Students will study the process of transpiration/transpiration pull and the role it plays in water/nutrient movement in plants. They will study the role of stomata in relation to the transpiration process using a potometer to examine the rate of transpiration in a bean seedling under a select set of environmental conditions. They will also examine the location/density of stomata from a leaf surface by preparing a stomatal
