The cartoon kids, Mateo y Cientina, present thirty experiments and activities for kids 7-10 and their families. The site includes resources and ideas for families and teachers.

The activities are intended to:

• help adults and children alike to overcome their fear of math and science;
• encourage families to spend time on subjects important to academic achievement;
• introduce families to local resources that support the project's mission.

Lawrence Hall of Science at UC Berkeley teamed with New America Media, a network of ethnic media, and with the Children's Museum of Houston and the Miami Science Museum, with funding from the National Institute of Science, to develop this project.
