Students observe seasonal images of Monthly Leaf Area, looking for any changes that are occurring throughout the year.

This mini-lesson guides students' observations of soil moisture anomalies (how much the moisture content was above or below the norm) for the continental US in May 2018.

Watch the video and have students answer the questions about Earth's cryosphere.
