Question

The challenge was to make a model that actually moved like the part that was being modeled. The students were given the materials listed in the table above and were asked to work in groups of 3 - 4 students. One group constructed the hand you see here:

The students in this group constructed a hand with three fingers and a palm. Noticed the arrows pointing to the nylon cords. The cord feature was added to represent the bones in the palm of your hands. Another student group commented on this design. "You should put the cords in the straws and then tape them into the palm."

What would this change represent in the prototype hand?

A) bones (straws) and skin (cords)
