Lichens are all around us — on trees, rocks, and even some buildings. But, what is a lichen? And what good are they? Lichen scientist Manuela Dal Forno will help students understand the special symbiotic relationship inside each lichen. She will show students the different steps she takes to study lichens: finding them in nature, looking at them under a microscope, and analyzing their DNA. She will share why we care about lichens: Understanding the life around us is important for understanding nature and how environments are changing. For instance, many lichens are indicators of air quality and others provide habitats for insects and nest material for hummingbirds.
Throughout the broadcast, Manuela will take questions from your students via text chat and there will be opportunities for students to share what they think using live polls.
Skills: Throughout the program, we will emphasize the basic science skills Manuela uses that students also possess: making observations in nature, identifying patterns, working on a team, asking questions, and sharing information.
Archive: We originally broadcasted this show as "Exploring the Amazing World of Lichens" on March 28, 2019. View the archived webcast. The November 14 show will be live and cover the same concepts.
