Betsy DeVos was all smiles on Friday as she toured the world’s largest robotics competition and congratulated student contestants.

The event was her first visit to Detroit as education secretary. DeVos, a Michigan-based philanthropist before joining the cabinet, has a long history of involvement with the city’s education policies.

It was a friendly environment for the secretary, who has often faced protesters who disagree with her stance on private school vouchers or changes to civil rights guidance at public events. (Even her security protection appeared to be in a good mood on Friday.)

Here are four things we noticed about DeVos’s visit to downtown and the FIRST Robotics World Championship.

1. She got to talk to some local students after all.

DeVos didn’t visit any Detroit schools, and didn’t answer any questions from reporters about education in Michigan. But as she toured the junior LEGO competition, she did stop to talk to a handful of Girl Scouts from the east side of the city.

2. She knows a thing or two about beluga whales.

She also stopped to stop to chat with students from Ann Arbor who called themselves the Beluga Builders and designed a water park that economizes water. DeVos asked how they came up with their name, and they told her how much they love the whales. “They have big humps on their heads, right?” DeVos said. “Yes,” they answered in unison.

3. She is an amateur shutterbug.

She stopped often during her tour to shoot photos and videos with her own cell phone. She took photos of the elementary and middle school students’ LEGO exhibits and photos of the robotics competition.

4. She was eager to put forth a friendly face.

As she stopped by students’ booths, she often knelt down to children’s eye level. When she posed for group pictures, she directed students into position. And she shook lots of hands, asking kids questions about their projects.
