7th-Graders Discover Mysterious Cave on Mars

A group of seventh-graders in California has discovered a mysterious cave on Mars as part of a research project to study images taken by a NASA spacecraft orbiting the red planet.

The 16 students from teacher Dennis Mitchell’s 7th-grade science class at Evergreen Middle School in Cottonwood, Calif., found what looks to be a Martian skylight—a hole in the roof of a cave on Mars.

The intrepid students were participating in the Mars Student Imaging Program at the Mars Space Flight Facility at Arizona State University.  The program allows students to frame a research question and then commission a Mars-orbiting camera to take an image to answer their question.

The newfound hole on Mars resembled features seen on other parts of Mars in a 2007 study by Glen Cushing, a U.S. Geological Survey scientist.

Cushing suggested that these anomalous pit craters are like skylights—places where a small part of the roof of a cave or a lava tube had collapsed, opening the area below the surface to the sky.

The caves are thought to result from volcanic activity on the red planet. At some point lava channels likely carved out caverns in the rock, and then left behind tunnel, or “lava tubes,” when the eruptions were over. They would have been covered when a solid ceiling of cooled material settled on top, and then sections of the ceiling likely collapsed at some point to form the skylight entrances.

Scientists aren’t sure what type of materials or deposits could be stored inside.

“This pit is certainly new to us,” Cushing told the students.  “And it is only the second one known to be associated with Pavonis Mons.”

He estimated the pit to be approximately 620 by 520 feet (190 by 160 meters) wide and 380 feet (115 meters) deep at least.

The young researchers had initially set out to hunt for lava tubes, a common volcanic feature on Earth and Mars.

“The students developed a research project focused on finding the most common locations of lava tubes on Mars,” Mitchell said.  “Do they occur most often near the summit of a volcano, on its flanks, or the plains surrounding it?”

The class commissioned a main photo and a backup image of Mars’ Pavonis Mons volcano, targeted on a region that hadn’t been imaged up close.

The pictures were taken by NASA’s Mars Odyssey orbiter using its Thermal Emission Imaging System (THEMIS) instrument.  Both images showed lava tubes, as the students had hoped.

But the backup photo provided another surprise: a small, round black spot. It was a hole on Mars leading into the buried cave, researchers said.

The students have submitted their site to be further imaged by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter, which could reveal enough detail to see inside the hole in the ground.

“The Mars Student Imaging Program is certainly one of the greatest educational programs ever developed,” Mitchell said.  “It gives the students a good understanding of the way research is conducted and how that research can be important for the scientific community. This has been a wonderful experience.”

Finding My Student’s Motivation of Learning Through Engineering Tasks

Posted: Wednesday, July 12th, 2017

by Huda Ali Gubary and Susheela Nath

It’s 8:02 and the bell rings. My students’ walk in and pick up an entry ticket based on yesterday’s lesson and homework. My countdown starts for students to begin…3, 2, 1. Ten students are on task and diligently completing the work, twenty are off task with behaviors ranging from talking up a storm with their neighbors to silently staring off into space. This was the start of my classes, more often than not. My students rarely showed the enthusiasm for a class that I had eagerly prepared for. I spent so much time searching for ways to get my students excited about the concepts they were learning. I wanted them to feel a connection to the lessons and come into my class motivated about what they were going to learn next. I would ask myself how I could make my class memorable where the kids were in the driver’s seat of learning. Incorporating engineering made this possible. Learn More…

Teaching Science in the Time of Alternative Facts – Why NGSS Can Help (somewhat)

Posted: Wednesday, July 12th, 2017

by Peter A’Hearn

The father of one of my students gave me a book: In the Beginning: Compelling Evidence for Creation and the Flood by Walt Brown, Ph. D. He had heard that I was teaching Plate Tectonics and wanted me to consider another perspective. The book offered the idea that the evidence for plate tectonics could be better understood if we considered the idea that beneath the continent of Pangaea was a huge underground layer of water that suddenly burst forth from a rift between the now continents of Africa and South America. The waters shot up and the continents hydroplaned apart on the water layer to their current positions. The force of the movement pushed up great mountain ranges which are still settling to this day, resulting in earthquakes along the margins of continents. This had happened about 6,000 years ago and created a great worldwide flood. Learn More…
