On Monday, October 12, 2020, the German Research Vessel Polarstern sailed back into its homeport after completing a remarkable expedition to the Arctic Ocean. This day marked the end of the fieldwork portion of the 2019-2020 MOSAiC expedition in which hundreds of scientists from around the world spent a year in the Arctic gathering important climate datasets.

Students will examine sunspots and track them at different latitudes on the Sun.
This activity is adapted from the Tracking Sunspots activity on NASA’s Solar and Heliocentric Observatory (SOHO) website (2009): https://soho.nascom.nasa.gov/classroom/for_students.html.
Objectives:
Students begin to familiarize themselves with solar activity by tracking sunspots at different latitudes on the Sun.
This activity is designed to get students thinking about
When radioactive elements decay they emit high-speed particles. These can be detected by use of a cloud chamber. The cloud chamber was invented by Charles Thomson Rees Wilson in 1911. The chamber works by saturating the air inside with alcohol vapor. Cooling the chamber with dry ice supersaturates the air. The energetic particles produced by the radioactive decay ionize
