Spark!Lab Science Experiments for Kids

Spark! Lab is a web site from the Lemelson Center at the Smithsonian's Museum of American History.  Spark! Lab  contains a number of simple step-by-step experiments that you can do with your students to get them interested in STEM (Science, Technology, Engineering, and Mathematics) topics.  Experiments range from creating a musical whirligig and hydropnic gardening to building a skyscraper and creating your own wind turbine.  The site also includes resources for educatorsprofiles of inventors & oral/video histories, and the stories behind a number of everyday products that were once innovative inventions (like the "bendy straw").
