Science NetLinks offers online learning resources for the educational radio program Science Update. This Web site contains an audio file and a transcript of a recent Science Update program called Eavesdropping Plants. The program describes research on how plants communicate with one another chemically. Discussion questions follow, helping K-12 students explore the material and think about the experimental process. Links to the homepage of the University of California Botanical Garden and an article from the Ontario Science Centre offer good sources for further research.
