This is the time of year those of us in the northern U.S. take pictures of foliage. We taunt those in warmer parts of the company who are stuck with the same view all year. I guess they have their turn when the temps here head below 0.
The change in the color of leaves offers an opportunity to combine photography with a little science. What produces the different colors and why do different trees change in different ways? There is plenty of information online allowing educators to take advantage of this opportunity. I happened to encounter a relevant source offered through Newsela. The nice thing about Newsela is that same content is provided at multiple reading levels. You may find this link of some value.
