Google Arts and Culture is a wonderful tool designed to bring museums and cultural exhibits from around the world into the classroom. Students can explore museum pieces, time periods in history, 3D renderings of historical objects/nature, and even run experiments. Its easy to search for what you are looking for and will suggest related items as well. I would suggest having a look at Google Arts and Culture if you are looking to introduce new topics through students analyzing and exploring primary sources.
Pros
- Easy to search topics
- World renowned museum pieces at high resolution and in 3D
- Suggests related topics
- Not just for art
Cons
- Some topics are pretty slim
- Not as much background on pieces of art work as their might be at the museum
