Computers themselves can make errors in information processing because of defects in their hardware or software. Tools, such as thermometers and x-ray machines, provide us clues about what is happening inside the body. Technology has made it possible to repair and sometimes replace some body parts. Students investigate their own articulated skeletons by immobilizing certain hand joints and then performing everyday tasks. Students categorize the types of joints in the human body and compare the movement of mechanical devices to the function of human joints.
Students then conduct research to find out which joints have artificial substitutes.
