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
Exploration of the Antarctic continent did not occur until the late 1800’s, and the South Pole was first reached on December 14, 1911. Courage, planning, and technology have been the main components of Antarctic exploration from the earliest days. This classroom activity is designed to highlight the historical elements of the past 100 years of exploration in Antarctica and
Antarctica is the coldest, driest place on Earth with a fairly limited number of native species which have adapted to these extreme conditions over millions of years. As a result, it's not very likely that a non-native species would survive there . . . right? Actually ever since exploration and exploitation of the Antarctic region began in the 1800's
