Students in ms. wong's 6th grade science class were asked to design and build a model of some part of the human skeleton. 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 circled area. in all three fingers, three pieces of cardboard per finger are joined like this with rubber bands. these spots represent in the human hand.
