"Polytech" (which is a greek company) brought out recently, three STEM kits, for use into Primary education.
This particular video describes the performance of Polytech's, R-2 STEM kit (for ages 6+), using the abilities of MindPlus. MindPlus is a very capable Scratch like, programming environment application, used by educators to interface & interact mostly in real time, with various microcontroller boards.
R-2 STEM kit is Arduino Uno based and the kit's components (sensors & actuators) will be briefly discussed and accessed, using MindPlus's unique, online mode.
Watch, enjoy and be inspired!
