 * METHODS TO PRESERVE CHRISTMAS TREES **

The purpose of this experiment was to see different ways to protect a Christmas tree from losing needles. Christmas trees lose needles because of a gaseous called Ethylene; it is a hormone that tells the tree to shed. The experiment was conducted by placing three Christmas tree branches in 250mL of water, on with 10mL of bleach, one coated with hairspray, and one left dry. This experiment was performed to teach people how to preserve Christmas trees, it was concluded that hairspray and water protect the needles for the longest amount of time while bleach and no water kill the trees fastest. Hairspray and water both lost 0 needles, bleach lost 48 needles, and nothing lost 31 needles, hairspray did so well because hairspray is designed to make things stick.
 * ABSTRACT **

One improvement to the experiment would be more exact Christmas tree sizes. The Christmas trees were not all the exact same, in the future tree sizes with the same amount of needles could lead to more exact experiments. A future experiment could possibly test different myths about the trees. This experiment overall was a success, but with these changes it could be much better.
