Why Are We Seeing More Auroras? Solar Cycle Sunspots (1980s – present)
graph from Neil deGrasse Tyson; slow reveal by David Yerger
Type of Graph: Scatterplot & Line Graph
Purpose
This slow reveal is designed to support analysis and discussion of both the data and the design choices. The questions in the slide deck invite learners to examine trends, relationships, and possible interpretations. This graph comes from Neil deGrasse Tyson video called, “Why Are We Seeing More Frequent Auroras?” It shows trends in the number of sunspots in solar cycles over time, starting in the 1980s and going until present day.
