Stephen Hawking's Snapshots of the Universe

What it is/what you do with it: a set of 8 interactive experiments illustrating basic principles that control the universe plus extras: fact pages/diagrams/videos and book suggestions.

Sample activities include building a simple 'solar system' to learn how planets stay in orbit around stars or dropping virtual objects from the Tower of Pisa, Mount Everest or onto the Moon to learn about gravity.

What we liked: the concept. Excellent educational value: quality of the content, the way the content is presented, simple illustrations and diagrams, simple interactions, extra information and tips helping to understand the experiments.

What we didn't like: narration/spoken instructions would make the app even more fun to use. Some of the experiments are more engaging then others. We wish there were more contextual interactive features. Many external links (Twitter, Facebook, book suggestions).
