Rocky Mountain Bio Lab: Wildflowers

National Geographic

This video explores the work of environmentalist John Hart, a Professor of Environmental Science at U.C. Berkley. In the Rocky Mountains of Colorado, Dr. Hart has established an experimental laboratory in which he has artificially created and maintained a 3-degree increase in surface temperature of a plot of land, and documented the impact on plant species occupying the plot.

Video length: 3:37 min.

Teaching Tips

About the Science

  • Hart has established an artificial heating effect on the meadow plants, suspecting that the 3-degree temperature increase may result in the reduction of flowering plants.
  • Hart has been conducting this experiment since the 1970s within this ecosystem.
  • Results since 1991 show evidence of change in the abundance of different species of plants as a result of the increased temperature.
  • Comments from expert scientist: This is a great resource. It's just a short video, but it does show something quite valuable- a very simple, easy to understand experiment.

About the Pedagogy

Technical Details/Ease of Use

  • A short 15-second commercial/advertisement at the beginning of the video may be distracting to some viewers.
