San Antonio hands-on children’s museum the DoSeum has landed nearly $285,000 in grants to expand an innovative exhibit that works to explain the perils of racial prejudice to kids in an age-appropriate manner. The DoSeum’s “Uniquely Us: Understanding Race and Building Unity” exhibit won the highly competitive $250,000 Museum for America grant from the Institute of Museum and Library Service (IMLS) and the $35,000 Smithsonian Institution Program Grant, museum officials said Monday. The IMLS grant will go to creating a traveling version of the exhibit, while the funds from the Smithsonian will fund professional development resources for teachers along with classroom-extension activities and an educator guide related to the exhibition.
