An elementary school in northern California will soon be the first in the country to have standing desks in all of its classrooms. 

Tracy Smith, principal of Vallecito Elementary School in San Rafael, joined the show along with Juliet Starett, who runs Standup Kids, the group that has been helping Vallecito make the transition. They told more about what this change has been like at the school. UCLA physical therapist Juliana Plank also gave a deeper look at standing desks for kids.
