How did cicadas evolve to go underground for so long? Why do cicadas spend so much of their lives underground? That’s what listeners Gus and Zachary want to know. This spring, up to a TRILLION cicadas will emerge across 16 states in the U.S., in an event that hasn’t happened since 1803. Cicada scientist Chris Simon helps us dig into the surprising science of cicadas - and figure out how they’re changing on this science podcast for kids.  Listen to our interview episode with Chris Simon, available to Patreon members who pledge at the $1 level or higher at patreon.com/tumblepodcast.  We also have free resources on our website - including maps of the emergence and links to download Cicada Safari, a citizen science cicada project. That’s on the blog at sciencepodcastforkids.com. Buy Tumble gear at our threadless shop! ¿Hablas español?
