A slide show about the effects of frost on Colorado wildflowers at the Rocky Mountain Biological Laboratory. Late spring frost damage has become more common in recent years, a consequence of earlier snowmelt. From research at RMBL by David Inouye and Carol Boggs.
Slides include pictures of the study site and study species, and graphs documenting the effects of late spring frost on wildflowers and a butterfly species.
ACTIVITY DESCRIPTION AND TEACHING MATERIALS

TEACHING NOTES / CONTEXT FOR USE
This slide show could be used to get students to think about unexpected consequences of climate change. For example, the fact that global warming could result in increased frost damage to plants (both wildflowers and some crops). Parts of all of it could be used.
Ask students what major points they learned from the slide show.
