A Demonstration of Photosynthesis and Transpiration
Students of all ages wonder what happens to a seed when you plant it in the ground. Try this basic experiment and let them explore, pose questions, and make predictions.
MadSci Network
Coloring Flowers
Demonstrate plant transpiration for your students using a white flower and colored water. This is an easy experiment that shows how a plant takes in water and nutrients.

Biology Wise: What Is Transpiration
Transpiration is an important plant process that releases water into the air through the stomata in leaves. This resource describes the process, the role the stomata play, factors that have an impact on transpiration, and why it is so...
Huntington Library
Huntington Library: What Plants Need in Order to Survive and Grow: Air [Pdf]
A lesson unit where learners work in small groups to examine stomata on a leaf's upper and lower surfaces. They then conduct an experiment to test whether plants can survive without air, learning about transpiration in the process.
