Relation of Plants to Moisture Science Project Idea

We all know that there is a close relationship between plants and moisture. How they give off water; how much they give off; and how the water is obtained are problems to be solved.

Do Plants Give off Moisture?

Under ordinary circumstances plants do not seem to give off water to the air, as the leaves remain fresh day after day. What happens, however, to leaves and flowers when they have been broken from the plant? What does this seem to indicate? How may these leaves and flowers be kept from wilting? The following experiment will enable us to find out if growing plants give off water.

Plant Transpiration Science Project Experiment

Completely cover the pot of an actively growing geranium or similar plant with rubber tissue or waxed paper, leaving only the stem and leaves of the plant exposed. Cover the plant with a dry bell jar. After a few hours observe and draw conclusions.

This process of giving off water by a plant is called transpiration.
