This is a very useful site with a great list of different iPad applications sorted by subject areas and then these are broken down in to different categories. The applications are both free and paid subscription/purchase.
For Example – Language Arts apps has sub categories for
- reading practice
- hand writing
- graphical organisers
This is a useful reference site - http://www.tcea.org/ipad
It is also worthwhile reading the Educause – Seven things you should know about iPad apps for learning. This is another excellent synopsis that helps clarify the use of iPads in the classroom.
For the Scientist, here are some free iPad applications that I have recently added to my laptop:
