Welcome to autumn, its stunning foliage, and the chemistry behind it! 🍁 In summer, leaves are filled with green-colored chlorophyll. The chlorophyll soaks up the sun’s rays, converting light into sugars that trees use to grow. 🌳 As temperatures drop and days shorten, there’s not enough sun for trees to grow. So chlorophyll breaks down, giving other colored chemicals their day in the (shorter) sun. 🌞 #msichicago #msideepscience #fallcolor #autumn #learnonig #fallcolors #chemistrylove #scienceisawesome #scienceiscool #fallleaves
