Once upon a time, Goldilocks went into a kids program and tried robotics. The first robot she tried was too hard so he got confused and overwhelmed. The second robot she tried was too simple so she got bored. The third robot was JUST RIGHT so that she became excited and learned some new cool things.
At our workshops, we engineer our activities (pun intended) to strike a good balance on the difficulty spectrum. This means that we are constantly creating our own hands-on activities utilizing a range of open ended materials like cardboard, K'Nex, lego instead of relying 100% on off the shelf products and activities.
