High Touch High Tech of Connecticut educator Aric Wellman visited all of the third grade classrooms at Middle Gate Elementary School on Tuesday, January 17, to share lessons on fault lines, volcanoes, and rocks.sciencemadefunct.net

During one presentation in teacher Robyn Cologna's class, Mr Wellman said the point of the lessons was to share that rocks are recycling all of the time, and there are so many rocks that have importance for humans.

When explaining fault lines, Mr Wellman asked the students what they think happens when pressure builds.

"What do you think we feel on Earth when that happens?" he asked.

One student responded, "An earthquake."

When describing how rocks start at the bottom of volcanoes, Mr Wellman named one rock on the side of Mount St Helens in Washington "Henry." He shared pictures of Henry before Mount St Helens's eruption in 1980 and after the eruption, to show how Henry moved when "his mother blew her top."

"We're going to get started with our very first experiment," said Mr Wellman, before describing the Gold Rush of 1842. The third graders, he said, would search through sediment for small pieces of rocks. All of the students were given pans and cups of sediment to search through.

"Look what I found," one student said, holding up a sample.

"Look at these cool rocks I found," another said.

"There are really cool things you can find in sediment," said Mr Wellman, "but you have to look for them."

After collecting samples, Mr Wellman said the students would learn how to study the properties of the samples to determine what types of rocks were collected.
