Environmental Challenges Facing Plant Communities

in the 21st Century:

The Holden Arboretum Scientist Lecture Series & Classroom Applications

Delve deeper into the current environmental issues, conditions and challenges that impact the natural world around us. This series of four Scientist Lectures will allow you to step back into the classroom and learn from experts at Holden, John Carroll University, Rutgers University and the USDA Forest Service. This embedded class is designed to allow you to connect what you learn with your classroom. Not only will you further your own knowledge about current research by learning from experts in the field, but you will research and design ways to apply this new found information to your current classroom practices.


You will be able to select the number of lectures you will attend (1-4). That will determine the time you need to spend out of class researching, analyzing, planning and designing how to incorporate these topics into your current teaching assignment. There will be a follow up session in May to share ideas and activities for classroom application.


All lectures are from 7-9 pm at The Holden Arboretum's Corning Visitor Center.
