The Slidepaths app is made by LEICA. A companty most famous for creating quality microscopes and digital imaging machinery. If your classroom does not have a microscope available, this app may be the next best thing. Students can learn about preparing a slide as well as view pre-made slides on their iPad. The app comes with several pathology slides for demonstration that could be a useful starting point in your lesson. Specific slides can be purchased through the app if needed. Teachers working with younger students may get the app on their teacher ipad. It is not currently available for students in grades 3-8.
