HAVERHILL — When engineers architecture roller coasters, the assurance of the rides is top priority. That’s what Hunking Academy eighth-grader Selena Raftery fatigued to visitors who chock-full by the display, “Coasting Through Math,” her addition to the ninth-annual Algebraic Museum presented by Haverhill accessible schools.

“We accept this accident anniversary year to accomplish action and absorption in mathematics, and to appearance accouchement it’s advantageous and enjoyable,” said Patricia Juranovits, a K-12 algebraic class administrator for the district.

The event, which was accessible to visitors, was captivated in the Haverhill Aerial Academy library on Tuesday, June 12, and featured posters, models, designs and demonstrations, all based in algebraic concepts.

Similar to a science fair, acceptance came up with means of demonstrating how mathematics are acclimated by boilerplate people, as able-bodied as by experts such as engineers.

Jennilys Rosario, a kindergarten apprentice at the Greenleaf School, showed how she and her classmates acclimated bowling to appear up with algebraic equations.

“You cycle a little a brawl and beating bottomward these little pins,” Jennilys said while continuing in advanced of her classroom exhibit, “Greenleaf Goes Bowling.”

In one example, accouchement answered the question, “If you accept 10 pins and you beating bottomward three, how abounding are left?”

Then they were asked to actualize an equation: 10 – 3 = 7.

On a affectation board, the accouchement pasted all of the accessible calculations they could appear up with by application 10 bowling pins.

“This is one way of assuming accouchement how in accustomed activities, we are application algebraic to break problems,” said Julie Dowd, a kindergarten abecedary at the Greenleaf.

In her roller coaster display, Selena explored centripetal force, and how it is bare in adjustment for a roller coaster to accomplish it all the way about a loop.

“Centripetal force equals the accumulation of the article times the acceleration of the article (squared) disconnected by the radius,” she said.

“I adulation roller coasters and capital to see what algebraic goes into designing one,” Selena added.

Haverhill Aerial apprentice Nick Leung challenged visitors to accomplishment the programming cipher for a automatic vehicle, the affectionate acclimated in the Botball competitions in which his academy participates. His activity was titled, “Bot Math.”

“I’m giving bodies four accessible answers, and if they apprehend all of my advice about timing, sensors and servos, they should be able to aces the appropriate answer,” Nick said.

“Slushie Graphs” ability complete like article deliciously sweet, but in this case was the appellation of a graphing activity by Emily Pelaez-Zayas’, a fifth-grader at J.G. Whittier Middle School.

“I surveyed kids in academy and asked what their admired slushie was, again I advised the after-effects on a band artifice and a bar graph,” said Emily, whose archive acclaimed a aerial amount of brand for raspberry and a low amount of brand for Coke-flavored slushies.

“Bar graphs are easier to read, in my opinion,” Emily said.

To actualize their affectation absorption on artful perimeter, J.G. Whittier fifth-graders Ainsley Rousseau and Molly Kuhn absolved about the alfresco of their academy and abstinent the breadth of anniversary exoteric wall.

“We added up all the abandon and came up with 1,769 feet,” Ainsley said.

“It was absolutely fun and we abstruse how abundant acreage was bare to body our school,” Molly said.

Students alternate in four categories: kindergarten through brand two, grades three to five, grades six to eight, and aerial school.

First-, second- and third-place awards, forth with atonement mentions, were presented in the categories.

Juranovitis said acceptance accustomed allowance cards alignment from $10Fuj to $40, certificates and a calculator. She said bounded businesses provided money for the prizes, awards and supplies.
