Hodge structures enrich the cohomology of a variety with a filtration dependent on the complex structure, providing a very rich geometric invariant and an essential tool in many areas of modern algebraic geometry. By studying hyperelliptic curves we can introduce a number of important tools and techniques very geometrically and very explicitly. We will cover topics from a subset of: Period domains and the Siegel upper half space, Picard-Fuchs equations, Torelli theorems and the Abel-Jacobi map, degenerations of Hodge structures and mixed Hodge structures from log poles. In particular I hope this will be accessible for beginning graduate students but also of general interest.
