A tree's leaves are in trouble when winter comes because they might freeze from the cold. In order to survive, all kinds of trees either have to somehow protect their leaves or get rid of them. Evergreen trees—your pines, spruces, firs, etc.— went the protection route. Their leaves, or needles, are covered in a waxy coating to resist freezing, allowing them to live for years or even decades before falling off and being replaced. The leaves of deciduous trees (like a maple, an oak, a birch, or a poplar), on the other hand, are dropped once winter is on its way. Chemistry is the reason why we have such beautiful colors of leaves in the fall!
(1) Read the article on "Mental Floss" to discover exactly how it all happens:

(2) Write a comment that explains your best understanding of why leaves change color in the fall. Why do they turn different colors? What is it that makes each color? Put it into your own words. This practices summarizing. :)
(3) Go outside and find five leaves, one of each color: (green, yellow, orange, red, and brown). Take a picture of all five leaves and post it on your blog with an explanation of why leaves change colors in the fall. (You can use what you posted in Step 2 above if you want.) Be as specific as you'd like, but don't plagiarize anything!!! Put it into your own words by summarizing!
