Thanks for kicking off this topic, Helga!
Additional Lego Lesson Ideas and Resources
Bricktestament.com ....this is a rather famous site, but should be only viewed by adults looking for creative brick-building techniques for scenes and props in famous Bible stories. It was originally created by someone who took some comedic liberty with the stories.
YOUTUBE has a bunch of LEGO Bible Videos created by teachers, kids, and some budding film-makers. Search for "Lego + Your Bible Story" and a bunch will pop up. These "shorts" could be used to kick off your lesson and inspire your creators.
You can also make your own LEGO videos quite quickly by using these three shortcuts:
1) Instead of the "stop-animation" seen in the YouTube videos, use rods to move characters as the camera is rolling (thin dowels work well). Use "Fun Tack" putty to quickly stick Lego characters to the rod and to stick props to the characters.
2) Video with your cellphone videocamera. Extend it at the end of a selfie-stick for greater mobility and to stay out of the way of the Lego-teers.
3) Assign someone to move the characters, someone to narrate the story, plus someone to provide sound effects.
