Kenilworth Science and Technology School eighth-graders Queasia Stafford and Andrew Knott will participate in the Mostratec Brazilian Science and Technology Fair, marking the third straight year students from the school have been invited to an international competition.

The fair is Oct. 26-30 in Novo Hamburgo, in the Brazilian state of Rio Grande do Sul, a news release said.

Stafford and Knott were selected on the strengths of their individual projects and are two of five students from the United States chosen to participate.

Stafford’s project examines whether fluorogypsum, a byproduct of hydrofluoric acid production, may be a better product to use than limestone in building coastal protection structures. Her project recently was recognized by the Louisiana Department of Environmental Quality with a Pollution Prevention award.

Knott’s project studies which geometric pattern of cellphone towers gives full cell coverage while deploying the fewest number of towers (answer: a hexagon). His project also theorizes that bees build their bee hive cells in hexagons because of the shape’s inherent efficiency.
