Bronx children made their way to Lehman College to learn about science.

The City of Science event is held once a year in each borough. The program is free and is aimed at teaching children about the world around them.

The Bronx version featured robot-building stations and tug-of-war on wheels. Those who attended learned about momentum, friction and other scientific theories.

The event is a smaller version of the larger World Science Festival that is in its 11th year.

Manhattan will host the next City of Science event in June.
