Explore Citizen Science

How do you celebrate sustainability and the environment while reaching out to students, teachers and residents in a way that will excite them about citizen science and “going green?”

In 2003, Temple Ambler presented the answer to that question on a grand scale, developing an outdoor, educational celebration of Earth Day — EarthFest!

About EarthFest

As EarthFest turns 18 in 2021, it has adapted — just like nature — to best serve our students, teachers and families by offering our programs virtually.

Our mission is to provide meaningful, impactful educational experiences for all ages throughout the year. Instead of one day and one event, we invite you to celebrate the Earth virtually!

EarthFest events are designed to provide more personalized opportunities to interact with our exhibitors and students to get hands-on with citizen science. Join us to stargaze, celebrate Earth Day, campout on campus and explore all life in our woods!

EarthFest Programs

The need to share ideas about sustainability and protecting and preserving the environment is critical, now more than ever. Temple Ambler EarthFest will host a variety of events, in cooperation with the Ambler Arboretum, the Temple Ambler Field Station and other partners, designed to get people thinking about and connected to the world around us. Learn more about each event using the links below. Suggested ages are listed. Most EarthFest events are free.

Celebrating The Earth
April through May, 2021

Celebrating the Earth highlights World Water Day, Earth Day and Arbor Day! In addition to a variety of information, resources and activities, throughout Celebrating the Earth, we invite classrooms and families to learn about careers focused on environmental research, the green industry, sustainability, education, advocacy and STEM — careers that are working diligently to create a better tomorrow around the globe!

Great American Campout
July 2021

Temple University Ambler EarthFest Presents and the Ambler Arboretum of Temple University are excited to provide essential information about camping, hiking and exploring nature for new and experienced campers alike. Rather than a day or a weekend, through these webpages, we're going to be celebrating the National Wildlife Federation’s Great American Campout all summer and fall!

Science of Scary

Gain a deeper understanding of the wonders of nature and the amazing things that may be found right in your own backyard. Connect with the world around you by learning about animals and insects such as skunks, spiders, predatory birds, snakes, sharks, scorpions and carnivorous plants!
