NORTH CALDWELL, NJ – There were some rumblings in the West Essex hallway outside of Jamie Wall's Environmental Science classes last week, and they weren’t coming from thunder or fireworks; rather, they were the eruptions of some of the volcanoes created by Walls’ students.

Students in Walls’ class formed groups to create the themed projects. Next, faculty voted for the winners, with the SMASH Burger volcano, boasting an "ash,” winning first place.

"Making the volcano helped me learn the vocabulary for the volcano unit, which I did not really understand," said Evan Katz of North Caldwell.

Evan and his group, including Peter Molina and David Kolesar, made a volcano featuring a bun, which was a crater; lettuce, which was carbon dioxide; and a pumice tomato. The burger was the conduit.

"I learned how volcanoes work and what they look like," said Paige Johnston who made a "Family Guy" volcano with her group.
