earth science week logo

This week (October 8-14, 2017) is Earth Science Week and the theme is “Earth and Human Activity.”

According to earthsciweek.org

“This year’s event, the 20th annual Earth Science Week celebration, promotes awareness of what geoscience tells us about human interaction with the planet’s natural systems and processes.

“Earth Science Week 2017 learning resources and activities are engaging young people and others in exploring the relationship between human activity and the geosphere (earth), hydrosphere (water), atmosphere (air), and biosphere (life). This year’s theme promotes public understanding and stewardship the planet, especially in terms of the ways people affect and are affected by these Earth systems.”

Be on the lookout for fun activities in schools and in the community to promote awareness of earth science this week, and National Fossil Day this Wednesday.

Extremely Hard Water

A metal pipe completely filled with white gypsum crystals

Everyone knows Kansas City’s water tastes really good, despite being “hard water.” Kansas City municipal water averages 100 ppm (CaCO3 equivalent), which is classified as “moderately hard” by the Water Quality Association. But these people’s hard water would be off the charts!

A valve was stuck in a pipe somewhere in the Naica mining complex in Chihuahua, Mexico. “The valve was removed with the aid of a saw, and voila! the pipe was completely clogged with fine, colorless and gemmy gypsum crystals to 7 cm.”

No word on what they did with the crystals after they unclogged the pipe.
