There are lots of great things to love about fall. There’s cooler weather, apple picking, Halloween… but arguably one of the best things is the natural art show that deciduous forests put on. Every fall these forests turn from their typical green to vibrant hues of red, orange, and yellow. It’s a spectacular site to see and one that people travel miles to visit (in Vermont we call them leaf peepers). But what’s the story behind this beautiful show of color, and why don’t all trees do it? As always, there’s some pretty cool science happening behind the scenes.
What’s the weather like right now? Let me guess, you just glanced out a window? Or maybe you consulted the meteorologist in your pocket. Either way, odds are most people reading this won’t be outside. After all, Americans spend 87% of their time indoors. As a result, the weather is much less a constant concern of ours than a welcome reminder that nature still exists beyond our buildings.
Humans are great at creatively conspiring against Earth’s elements, and the temperature is no exception. In addition to buildings, we’ve invented clothes to cover ourselves, thermostats to tinker with the temperature, and numerous other nature-numbing devices that solve the challenge of changing climates.
June brought educators from around the country to Washington, DC, to experience Smithsonian research facilities, interact with scientists, and engage in activities to bring back to their classroom. These educators were participants in the Smithsonian Science Education Academies for Teachers (SSEATs), a weeklong event that focuses on the professional development of science educators.
