The rate of transpiration in a plant varies depending on a range of conditions, including light intensity, relative humidity, wind speeds and temperature, as well as between plant species various immediately plunge the cut end of the stem in the sink of water and remove the bottom 2-3 cm of stem with sharp scissors. In groups of 3-4 (same groups as you worked in for the leaf peel experiment), choose a variable which you think will have an effect on plant transpiration (eg light exposure) record the variable on worksheet 7b transpiration 2 develop a hypothesis about how this variable will affect the rate of plant transpiration record.

Student groups are given two small plants of native species and materials to enclose them after watering with colored water after being enclosed for 5, 10 and 15 minutes, teams collect and measure the condensed water from the plants' breathing, and then calculate the rates at which the plants breathe. In this enlightening transpiration experiment, kids will explore how the loss of water from plants through transpiration contributes to the water cycle. Class practical in this activity the rate of water uptake, due to transpiration, by a shoot from a woody plant, is measured by timing how long a bubble takes to move a set distance, in the this could be a demonstration or an experiment for groups of up to three individuals – observer, timekeeper and scribe.
