Authentic Plant Pollinator Landscape Research for Education (APPL-RED) was a teacher professional development program that ran for secondary science educators in the summers of 2017 and 2019. The program focused on cutting-edge plant pollinator research at the Penn State Center for Pollinator Research and various research techniques used in this interdisciplinary field. Teachers at the workshop learned about plant-pollinator interactions, pollinator habitat, and pollinator decline. This page contains resources from the APPL-RED teacher professional development.
