On Wednesday, Phil Mickelson wore shorts and flip-flops to Callaway headquarters in Carlsbad, Calif., where he celebrated his British Open victory with the troops responsible for his clubs and ball. On Friday, he put on a suit and made the rounds in New York City, where he and wife Amy rang the closing bell at the New York Stock Exchange.

The Mickelsons also used the visit to promote their Mickelson ExxonMobil Teachers Academy, which for the ninth year is putting on a week-long program at the Liberty Science Center in Jersey City, N.J., to help get grade-school students exposed to and interested in math and science. The program isa collaboration between the Mickelsons, ExxonMobil, the National Science Teachers Association and Math Solutions.

"Math and science is huge for me and my success," Mickelson said on CNBC's Squawk on the Street. "Winning this championship, I look at the one thing that has really changed my game and it's been the 3-wood that I have been using. I'm a high-spin player and this 3-wood takes off half the spin that I was putting on it, which gets the ball boring through air. Consequently, I hit the two best 3-woods of my life on the 17th hole to win."

The science and technology behind modern club design, he said, is helping him play some of the best golf of his career, even as he approaches his mid-40s.

To help promote the education program, the Mickelsons were joined at the closing-bell ceremony by some of the teachers from across the country that'll lead this year's programs, which are held in Texas and Louisiana in addition to the one in New Jersey. To date, more than 3,600 teachers and 230,000 students nationwide have participated in the academy.
