The 1960's is such an interesting period in time. The way this resource navigates and teaches information is amazing! I love the way you sorted things into categories (people, events, terms). It's helpful for students sometimes to have things sorted for them if they are struggling to make meaning of so many ideas.
One consideration for this project would be to add video and audio. For example, the questions that have quotes or talk about musicians would be great areas to add in media so students can further connect the knowledge.
This is outstanding!!!
The navigation is fabulous... I didn't find any gaps or missing links. Great job!
