Water from a Tree

Earth Day is coming! How will you help your residents celebrate our planet from inside their rooms?

Science for Seniors has the answer. Do a live experiment residents can watch unfold from their window. Explain how trees put water back into the atmosphere.

Materials: One sandwich bag, tape and a broad leaf tree.

Process: Tape the bag over one leaf of the tree near a window where residents can observe. Remove one week later and show residents watching from their windows what is in the bag.

Result: Trees put water into the air through transpiration. A large oak tree can transpire up to 40,000 gallons a year according to water.usgs.gov.
