In this activity, students will build a model to simulate parts of the water cycle. They will be able to recognize and explain the essential elements of the water cycle.
Resource Type: Activities
As Earth’s population increases, human impacts on all the parts of the Earth system also increase. What are these impacts to air, water, land, and life, and why do we refer to our present time as the Anthropocene?
Resource Type: Information
Students match graphs showing aspects of observed climate change with statements that describe the observations.

When climate conditions, such as temperature and precipitation, vary from the expected averages this is called climate variability. Natural changes in the Earth system can cause climate variability, but scientists are concerned about climate variability resulting from human-caused climate change.

This video describes how climate scientists use "proxy data", such as the information stored in ice cores, to study climates of the past.

The troposphere is the lowest layer of Earth's atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.
Drought can occur anywhere in the world and harm people and ecosystems. Drought is becoming more frequent and more severe due to climate change.
