This activity will help students better understand and practice estimating percent cloud cover.

GLOBE protocols and learning activities that complement the Volcanic Eruptions phenomenon through hands-on investigations are detailed. 

In this lesson, Observing Earth’s Seasonal Changes, students observe patterns of average snow and ice amounts as they change from one month to another, as well as connect the concepts of the tilt and orbit of the Earth (causing the changing of seasons) with monthly snow/ice data from January 2008

Use the Earth System Data Explorer to analyze data and make a claim about which 2018 eruption was larger, Kilauea, HI or Ambae Island, Vanuatu.
