Are you thinking value added products or topics related to beekeeping? To me, value added products are soap, lotions, lip balm, etc. To me, topics related to beekeeping would be nectar and pollen sources, pollination services, swarm education, observation hives, mead making, planting for pollinators, etc.
Is your audience beekeepers, wanna be beekeepers, or the public?
Will you be doing a powerpoint, hands on demo, or just talking?
