I am fascinated by Texas Bluebonnets and want to introduce them to k-12 students as a major source of Nitrogen fixation.
As I want to present this to the teachers can I get any guidance from you, like some hands-on activity about seed germination or nitrogen fixation that can be completed within 10 minutes?
A good place to start would be the Wildflower Center's article on Texas Bluebonnets which includes a short discussion of the species' capacity to fix nitrogen as well as a lengthy discussion on how to germinate bluebonnets. A succinct overview of nitrogen fixation may be found on Wikipedia. A more in-depth discussion of the topic may be found at Dr. David Dalton's Reed College webpage. We know of no simple teaching demonstrations for nitrogen fixation. However, it would be a simple matter to wash the soil off roots of bluebonnets and show the students what the rhizobium nodules look like along with a discussion of how they work.
