Three elementary school students from the Sachem Central School District thrived during the recent Brookhaven National Laboratory Elementary Science Fair, as they secured two first-place finishes and an award for honorable mention. 

Nokomis Elementary School fourth-grader Arianna Flores finished in first place for her experiment that examined how nanosilver found in common household products affects the growth of pond life. Merrimac Elementary School fifth-grade student Nicholas Prosa received first place for his experiment that determined the healthiest hand drying option, paper towels or hand dryers, and Audrey Prego, a third-grade student from Waverly Elementary School, was awarded honorable mention for her experiment on sleep.

To advance to the BNL Elementary Science Fair each student had to be awarded first place at their respective elementary school science fair. 

A crafty combination of durability and ingenuity steered students to success during a recent activity at Merrimac Elementary School focused on the westward expansion of the United States.

As part of the lesson that explained the historic 1803 expansion that followed the Louisiana Purchase, each fifth-grade class was challenged to design a miniature covered wagon that could traverse a simulation of the rough terrain that pioneers encountered on their journeys. Student groups were supplied with bottle caps, cardboard, straws and tinfoil to assemble a prairie schooner capable of protecting cargo simulated by blocks. 

The covered wagons were led over a canyon, mountains, plains and a river, all while being sprayed by water to represent rain. Following the initial tests, students had the opportunity to revise their designs and attempt to cross the treacherous terrain again. 

Through the covered wagon activity students learned a plethora of additional information, including the journey of Louis and Clark, the details of the Louisiana Purchase, the doctrine of manifest destiny and the countless challenges the pioneers faced.
