Essential Skeleton 4 is a great free app that lets you explore the human skeleton. The app allows you to pan and move around the skeleton, zoom in on different bones and get information about each one.
The ability to hear the name of each bone being read aloud is a nice feature. Teachers will also like the annotation and notes facility.
At a basic level of demonstrating the bones and how they fit together, this app would be suitable for upper primary. The language used in the descriptions would make it more suitable for secondary.
Download it from the app store here. Whilst the basic app is free, it is being used to showcase a larger more expensive suite of applications. Be aware of the buttons which will take you to the app store to buy it.
