Inspired by Derpi's short movies
http://creatingtomorrowschoolstoday.blogspot.com.es/2015/04/the-giving-tree-follow-up-by-derpi.html, Year 6 pupils are going to create stop-motion videos with Legos. We will use an app for Android devices called "Stop Motion Studio". There is another free app by Lego that offers you the possibility to add music, titles, etc., but it is only available now at the App store.
I will post the videos when they finish them.
Thanks to Joanna and Derpi for the idea and the nice examples.
