Life Science Students Complete 'Hands-On' Assignment
Seventh-grade Life Science students finished a unit on bones, muscles and skin with a "hands-on" assignment.
The students were tasked with creating a prosthetic hand prototype that is able to grab, lift and release. The class first worked on model hands made of silicone and powered by string, then students set off to create designs of their own. The use of recycled materials was encouraged and a $20 spending limit was set, but construction and mechanics were limited only by students' imaginations. The finished products, made of everything from cardboard to Lego parts, were tested by their ability to successfully grasp a tennis ball.
