Citizen Science

Be a Citizen Scientist!

This monthly natural history series for families introduces Zoo Members to the many citizen science programs in which they may participate in their backyards or local green spaces. As the name suggests, citizen science projects encourage amateur scientists to provide data for studies run by professional scientists. Each program includes fun activities related to the featured plants or animals in addition to an overview of the project of the month.  These programs are free but require pre-registration. (Please note: some of these projects require a short training session – these programs ar  introductions and not official trainings for these projects)
