In this activity, students explore three indicators of drought are: soil moisture, lack of precipitation, and decreased streamflows. Students investigate each of these parameters develop a sense for the effects of drought on land.  

Students play the role of nitrogen atoms traveling through the nitrogen cycle to gain an understanding of the varied pathways through the cycle and the relevance of nitrogen to living things. 

The activities in this guide will help students understand variations in environmental parameters by examining connections among different phenomena measured on local, regional and global scales.
