Falling leaves are synonymous with Autumn but that often means we overlook the evergreens. Evergreens keep their leaves throughout the year. Pines are a common evergreen found in the area and can be used for this simple experiment. How long can an evergreen survive without water and do other fluids provide enough water for the plant to live? Test this out and find out!
This experiment demonstrates the hardiness of evergreen trees. Some varieties of trees are resistant to salt so the results of this test should be very interesting! Even coffee can keep some of the branches green. You can try this test with other liquids to see what causes the branches to wither. Remember to document your findings as you learn a little more about trees! Try this with spruce, fir or pine trees to see what kind of differences occur between the species.
