Human Embryonic Stem Cells
Students use the Internet to discover information about human embryonic stem cells from the National Institutes of Health. They examine different sides of the debate to use or not to use stem cells. They can also listen to speeches given...
Curated OER
Spotlight On Stem Cells
Students discover the differences in how stem cells develop and function depending on their source. They see how scientists are using stem cells - from a variety of sources - to study how they can be used to cure certain illnesses and...
