Review these resources to learn how Dorothy "Dotty" Metcalf-Lindenburger explored different career paths to eventually make her way to work with NASA.  Starting off as a geology student in college, then working as a teacher, Dotty gained employment with NASA as an astronaut!

In this NASA-JPL lesson, students create a model of a volcano, produce and record lava flows, and interpret geologic history through volcano formation and excavation. 

This investigation introduces students to the significant environmental changes occurring around the world. The investigation uses NASA satellite images of Brazil to illustrate deforestation as one type of environmental change.

Students model Earth's tectonic plate movement and explore the relationship between these movements and different types of volcanoes.
