PBS stations and affiliates in the US are set to debut the first of six new half-hour episodes of STEM-based live-action series SciGirls next month.

The new eps will launch weekly on PBS-affiliate Twin Cities Public Television (TPT) starting April 17 at 5:30 p.m., as well as on PBS stations nationwide. Eps will also be available online beginning April 15.

The series stars girls from around the country as they explore STEM fields (science, technology, engineering and math).

For its third season, the show explores citizen science, a STEM frontier that gets the general public engaged in real science. The series follows groups of middle school-aged girls as they go on STEM citizen adventures like tracking toads, counting clouds, monitoring butterfly populations and improving urban bird habitats.

To coincide with the start of the new season, the property is getting a mobile-friendly upgrade  for its SciGirls website, including interactive videos and two new games.

The SciGirls creative team is headed by TPT’s director of science content Richard Hudson, exec producer of the PBS children’s science series Newton’s Apple and creator of DragonflyTV and the SciGirls initiative. Animation is handled by Boston-based studio Soup2Nuts, which recently announced it is shutting down at the end of April. On the interactive side, games and the mobile site are developed by Curious Media.
