Moving Machines: 10 Mega Models to Construct

My daughter and I made a pulley from this. My neighbor made the Lever and robotic arm. when she got confused she would always say that and ask for help. It was a little bit of mental jog for me to look at the final picture and hen see where the nuts and bolts should go. It is a fun project for kids. Like how they say you have to go down to climb the mountain, here to go forward ie to actually mvoe in the present, you have to look in the future and also look back to revise, if you have done it correctly. In the robotic arm, one said was moving well, while the other wasnt, which is what revealed, how the whole system works. When the tooth gears align, it moves well. When they are stuck, it doesnt. The reason for it was one of the gears under duress broke out of the gear mold and wouldnt go in under the top circle and hence the lack of mobility. Great way to engage kids, learn how things work and asking for help when you need it.
