Interpret the map, or model, to find patterns in the occurrence of tropical cyclones from 1842 through 2018.
Learn about volcanic ash and watch a visualization of the Calbuco volcano to see how ash travels around the world.
Using hourly graphs of PM 2.5 data and HYSPLIT model trajectories, students will collect evidence for the effects of fireworks on air quality.
In this activity students will make observations about the objects, size, distance, and motion of the Sun, Earth, and Moon during a solar eclipse.
Students observe how air quality changes over time, for a selected location, using data from the United States Environmental Protection Agency (EPA).
Students analyze surface air temperature anomalies to identify change with respect to different latitudes across the world.
Students will analyze a graph showing the amounts of peak energy received at local noon each day over the year changes with different latitudes.
Students analyze four data visualizations focused on the topic of sea level. They use a jigsaw method to explore and communicate their findings to their peers.
Students observe monthly images of changing vegetation patterns, looking for seasonal changes occurring throughout 2017. These data can be used by students to develop their own models of change.
