Description      The purpose of this activity is to allow students to learn about a specific biodegradable
                 material, which they will research and write an organized report about. This will let
                 students recognize the interaction of people in various fields of science and technology
                 in the process of developing biodegradable materials and gain exposure to some of the
                 different careers involved in development of biodegradable materials. It is not
                 necessary, but it is recommended that students visit a local research university or
                 institution to meet real life contacts working in a research field.

                                              Could biodegradable materials be used
                                              someday to make new body parts? Some
                                              researchers think so. They are presently
                                              developing biodegradable polymers that
                                              can be used to regenerate skin, bone, and
                                              other types of tissues. Human cells are
                                              grown on the polymers, which are then
                                              implanted in the body. The cells perform
                                              their specialized functions while the
                                              polymers degrade.

                                              Biodegradable materials have many
                                              applications in medicine, engineering,
                                              agriculture, and other areas.

                                                Do research to learn about a
                                                biodegradable material that interests you.
                                                The list to the left may help you select a
       topic. You may also select from the list of biodegradable objects you identified in
       Activity 2. Your report will be due at the end of the module.

                                         Use library references or online resources to

                                         interview experts in the field, such as
                                         bioengineers and materials-science
                                         researchers.
