Carlos Orozco enjoyed the volcano’s eruption so much he did it again.

And again.

And again.

“I think you’re done,” Katie Orozco told her son who was in the middle of another celebration while most other students had already packed up and left the field.

Orozco and other fourth graders at Hillcrest Elementary School in Oak Harbor had a blast Friday.

As part of learning about Washington state history, they have been studying volcanoes. The culmination of the learning experience was to build their own volcanoes and mix the right ingredients to create an eruption.

The result was about 135 small mountains all foaming over at once at the end of the school day Friday — with the aid of baking soda and vinegar.

“We celebrate this as part of a project to kind of extend their learning,” said fourth grade teacher Debbie Bryner. “We study volcanoes through social studies. It’s part of Washington state history, especially with Mount St. Helens being so local. That also connects with our reading curriculum because we have a couple of stories about mountains and the Grand Canyon and how things are formed. We can incorporate all that in there.”

The students also plot points on a map that reveals the topic of their project, the Ring of Fire, the massive horse-shoe shaped area around the edges of the Pacific Ocean where intense volcanic and seismic activity occurs.

Not only did students build volcanoes using their own imaginations, they first gave an oral presentation about them.

“We had kids making them out of Rice Krispies,” Bryner said. “We had paper mache. We had clay. We had duct tape.”

Each student had their own takeaway.

“I learned that baking soda and vinegar can ooze out of a bottle,” Sabina Taylor said.

“I learned that some volcanoes cause erosion,” Olivia Camargo said.

Carlos Orozco said he learned a lot about volcanoes, from their steam vents to their acid lakes.

“He has been looking forward to it,” Katie Orozco said. “He worked very hard on this project. He had a blast putting it together and definitely looked forward to the eruption.”

The lessons he learned inspired a new goal.

“To make volcanoes every day of my life,” he said.
