Understanding solar activity is relevant because the physical phenomena that cause it cannot be studied on Earth, and also because it allows us to predict space weather. Solar storms (coronal mass ejections) carry large amounts of charged particles that form auroras...

Using cheap, household items, we will build a tactile version of the Sun that can be used to identify the different characteristics of our star, like sunsposts. This cheap, tactile version of the Sun is a great resource to explore a star for both visually impaired and...
