Sam’s science homework for the next two weeks is to prepare a talk on a famous scientist to give to the rest of his class. He has heard the name 'Marie Curie' and he knows she was a great scientist, but he doesn’t really know what she did. He finds a pod cast about Marie Curie and listens to it a few times. It is just what he needs to give him the information for his talk. Listen to the same pod cast and then answer the questions about Marie Curie.
