Teaching nature sciences can be hard, especially for more abstract themes. Dáskalos makes learning fun and explorative again. Usable both for beginners and as an interactive reference book, it shows information about such diverse topics as platonic solids, optical lens systems, momentum conservation for pendulums, atom models with fusion, vector analysis and many more. The content is fully interactive and the interactions playful – and not boring and grey. The topics immediately become more tangible and easier to grasp, as they deal with spatial phenomenons that are hard to explain in books or static graphics. Knowledge can be transferred in a more direct way and is embedded in beautiful interactive models and systems which is one point badly missing from many AR applications today.

The submitted app is Dáskalos Chemistry, which shows the chemistry part of Dáskalos in action. The full periodic system is available, atoms and molecules can be observed and analyzed in augmented reality. They are accompanied by hands-on, printed learning materials. Moving an atom closer to you reveals the inner structure, including electronic configuration and properties. Moving it further away shows the color-coded structure of the element using the CPK coloring scheme, the most popular system for distinguishing chemical elements.

Dáskalos works both with tracking markers and without. The markers for the periodic system are available at: http://prefrontalcortex.de/labs/daskalos/periodicSystem.pdf

The teaching material samples can be found here: http://prefrontalcortex.de/labs/daskalos/teachingSample.pdf

They explain how the content can be used, what is shown, and provide additional textual information for the interactive models. Please print them out and use them together with the app!

Hold the markers in front of the camera to interact with the atoms and molecules. If you remove a marker, the molecule will stay, allowing you to build your very own AR learning space in front of you. This space can hold as many atoms as needed, making it easy to learn from comparing them with each other and to observe their properties while having both hands free to, for example, take notes. Also, you can drag the atoms around using the Moverio touchpad.
