“The Elements is probably one of the most common known educational apps, with focus on chemistry and the periodic table. The app presents the periodic table as living table where every element is displayed with a rotating sample. Each element can be selected for further information. It offers facts and figures from Wolfram Alpha, and can also list the up-to-the-minute market price if available” (Valstad, H., & Rydland, T. 2012 iPad as a Pedagogical Device, Norwegian University of Science and Technology p.55). Remember, if your students do not have iPads but you have one and you have a data projector, you can connect your iPad to your data projector and display your iPad screen for your students.
