The snow-covered hill near the football field and Windham
Primary School was packed with eighth grade and second grade students having
fun sledding on Friday afternoon, March 8. No, it was not recess. They were
studying chemistry.
Windham Middle School’s eight grade team of Ohana
Explorers led by teachers, Pamela Mallard, Lisa Hodge, Erika DuPont and Tricia
Sabine, were given an unusual homework assignment – to build a sled from
materials at home. They were given four weeks to make their creations, factoring
in the concepts of potential and kinetic energy. Specifically, they were
assigned to, “develop a model to describe objects interacting at a distance and
the different amounts of potential energy that are stored,” Mallard said. This
was the curriculum standard to which was learned and developed.
Briefly, chemists divide energy into two classes. potential energy is where the energy is stored while kinetic energy is the
energy found in a moving object. The faster the object can travel, the more
kinetic energy it has. “Students needed to be able to describe what the
potential energy of the sled was and where it converted to kinetic,” explained
Mallard. “The student also needed to identify the role of friction in
stopping their sled.”
Students were asked to determine the relationship between
the amount of energy transferred, the type of matter, the mass and the change
in kinetic energy. They also explored how adding a person to the sled,
which increased the mass, would change the amount of acceleration of the object.
“Students did an on-line program through Gizmo (an
interactive learning site) called Sled Wars,” explained Mallard. “This
gave them information to ponder while constructing their sleds. Sleds were
built at home and the students could have the help of a parent. I encouraged
the home connection
among family members.”
among family members.”
If a student didn’t have materials of their own, Mallard
offered materials from the school and they could stay to work on them after class.
The second-grade students who participated in this middle
school science project are part of a mentorship program. “We have been
mentoring Mrs. Brianna Butts second graders once a month since the beginning of
the year,” stated Mallard. “This allows the eighth-grade students to take on a
leadership role and make connection with their younger friends. It is something
we will continue to do for the remainder of the year.”
Eighth-grade student, Abby Thornton stated that the
project was a fun and engaging activity. “I never realized the true potential
of sledding. It shares a global meaning of fun and allowed us to see how
velocity, acceleration, speed, and other components contribute to real life.”
Lucas Spencer, another eighth-grade student, stated it
was a great learning adventure he experienced with both family and friends. “This
school project allowed for me to really make a home connection,” Spencer said.
“I am lucky that my little brother is on the buddy team at the primary
school. We have been brothers and buddies all year. We designed and
constructed the sled with the help of my Dad
and my uncle.”
and my uncle.”
The next mentorship program event will consist of the
eighth-grade students hosting a Grandparent Day in May for both groups. “This
allows us to make a generation connection with our buddies,” Mallard explained.
