LONDONDERRY — The world was their classroom, if only for a day.

On Friday, 7th-graders on Londonderry Middle School's Hurricane Team showed off their cultural learnings during the school's annual World's Fair.

Held in the school gymnasium all day Friday, the event featured music, food, costumes and dance from 31 different nations, including Egypt, Nigeria, South Korea, Kenya, Argentina, Brazil, Canada and Cuba.

Over the course of the school year, the students researched their projects, with groups of three assigned to each country.

Wearing a red, white and blue boa, student Dominique Faucher sang along as classmate Teagan Miller strummed her guitar. Sung to the tune of Beethoven's Ode To Joy, the lyrics featured fun facts about Great Britain, the girls' assigned country.

In a nearby booth, Owen McGrath sported a spiked helmet as he informed guests about his assigned country, Sweden, while Edie Feldmann wore a traditional red silks as she invited classmates to participate in an Indian-themed animal bean bag toss.

Wearing the authentic Indian sari she'd purchased for a family wedding last year, science teacher Jessica Payeur and a cluster of students formed a circle as they demonstrated an Israeli Zemir Atik dance on the gymnasium floor, gaining a round of applause from visiting students and parents.

Later students demonstrated other traditional dances from Russia and Ireland, as well as some moves from closer to home in the way of a New England folk dance.

In the corner of the gym, an International Food Court offered visitors a true taste of the nations, served up by helpful parent volunteers. Friday's fare included Swedish rosenmunna cookies, ginger nuts from New Zealand, pisang goreng, or banana fritters from Indonesia, Vietnamese meatballs and Irish potato pancakes.

“The kids really look forward to this every year,” geography teacher Marie Laliberte said, noting that in previous years the students had focused more on costumes, but food was the big focus at this year's fair.
