ABSTRACT
Students have several misconceptions about stem cells, stem cell research, and cloning. The topics of these misconceptions range from the location to the purposes of stem cells. Many students believe that adult stem cells come from adults and that embryonic stem cells come from children and infants. Students may also believe that stem cells can be implanted into a woman's uterus to produce a baby and that all stem cells come from placenta or embryonic cells. In addition to preparing the adult and embryonic stem cells, the authors also created a tissue chart. This chart identifies the type of tissues represented by the colors of yarn. The purpose of this activity is for students to be able to explain differences between embryonic and adult stem cells. The day after the initial activity, have students work in groups of three to do research online about differences and similarities between embryonic and adult stem cells.
