This is a STEM-based lesson that can be taught in class or online. Students will analyze Weddell seal pup growth data, collected by the Growing Up on Ice, B-030, research team. To use this lesson virtually, include the data cards and have students either construct graphs and upload an image of their graph, or construct a graph and share
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
