Check out this the Arctic and Earth SIGNs video to explore how climate models are used in climate change research.

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.

This activity is designed to introduce students to geologic processes on Earth and how to identify geologic features in images. It will also introduce students to how scientists use Earth to gain a better understanding of other planetary bodies in the solar system. 

The purpose of this activity is for students to create a desktop soil profile based on the biome region of the United States where your school is located.

In this activity, students investigate three different soil samples with varying moisture content. They use a soil moisture probe to determine the percentage (by volume) of water in each of the soil samples.

Watch NASA videos about aerosols and volcanic ash and answer questions.

Students will describe the changes in a newly-formed volcanic island over the first three years of its life.  

The students will review the NASA Space Place video, "What are Tectonic Plates?", and answer questions about tectonic plates.
