Devoted entirely to science for kids ages 9-12, DragonflyTV is a science program for kids, by kids! Every episode is different, and it’s all about kids showing the results of their investigations.
DragonflyTV’s young scientists chase a tornado, swim with dolphins, build robots, and test their pets’ intelligence. Plus, for teachers, parents and community workshop leaders, there are Teacher’s Guides available, with lots of ideas for investigations.
