Here are some top notch resources sights to bring you the buzz about bees:
One of the most surprising places I found a wealth of pollinator resources was the Friends of Flight 93 National Memorial commemorating 9/11. They have an entire tab dedicated to environmental education and the pollinators and the native birds that make the memorial their home. In addition to the 9 website resources they list to other sites, they also list two science-based Pollinator Curriculums: one for Kindergarten to Grade 2, and one for Grades 3-5. They also have a "Bee Reading List for Kindergarten to Grade 12."
Want to build your own bee hotel? National Geographic to the rescue with a lesson plan for students in grades 3-11. Here's another detailed blue print and guide from Michigan State University's Extension Office if you need it.
Additionally the 1 Million Women Facebook page has a mini movie about bee hotels. It showcases how they are helping to save and protect bees, who in turn are helping us!
