PAESTA Podcast Series: Episode 3 - How do Scientists Measure Rainfall?

You Asked, We Answered!

Transcript for the podcast

Many schools will have a rain gauge installed, where students can measure and record the amount of rain that falls each day. But scientists do not measure precipitation on the ground – they measure precipitation from space, using a combination of active and passive remote-sensing techniques, improving the spatial and temporal coverage of precipitation observations on a global scale.  You see, reliable ground-based precipitation measurements are difficult to obtain because most of the world is covered by water, and many countries do not have precise rain measuring equipment (such as rain gauges and radar). Precipitation is also difficult to measure because precipitation systems can be somewhat random and can evolve very rapidly. During a storm, precipitation amounts can vary greatly over a very small area and over a short time span.

PolarTREC NOW accepting applications until 09/08/15; real-world polar research experience


Applicaiton deadline: September 8, 2015

PolarTREC (Teachers and Researchers Exploring and Collaborating) is a program in which K-12 teachers spend 3-6 weeks participating in hands-on field research experiences in the polar regions. The goal of PolarTREC is to invigorate polar science education and understanding by bringing K-12 educators and polar researchers together. By fostering the integration of research and education, PolarTREC will continue the momentum established during the International Polar Year (IPY) by addressing the following program objectives:

PAESTA Podcast Series: Episode 2 - What is the Difference Between Paleontology, Archaeology, and Anthropology?

You Asked, We Answered!

Transcript for the podcast

These career fields are front and center in pop culture, thanks to Hollywood blockbuster films, such as the Jurassic Park and Indiana Jones series. Unfortunately, popular culture can sometimes blur the boundaries and misrepresent these disciplines. This podcast explores the differences between the three fields of paleontology, anthropology, and archaeology.

PAESTA Podcast Series: Episode 1 - How Do We Know CO2 is Increasing?

Atmospheric CO2 at Mauna Loa Observatory

You Asked, We Answered!

Transcript for the podcast

We know that atmospheric levels of carbon dioxide have been increasing because we have the data! The story of collecting CO2 data begins in 1958, when a geochemist from the Scripps Institution of Oceanography, Dr. Charles Keeling, started collecting measurements of carbon dioxide in the atmosphere at an observatory located over 11,000 feet in elevation on the Mauna Loa volcano on the big island of Hawaii. These systematic measurements Dr. Keeling started have become the most widely recognized record of human impact on Earth, linking rising levels of carbon dioxide from the burning of fossil fuels to the warming of the planet.

July 2015 PAESTAR

This month we recognize PAESTA Past President Laura Guertin, Professor of Earth Science at Penn State Brandywine. Not only has Laura just completed her second term as PAESTA President, she has received several accolades in the past month. She was voted a Fellow of the Geological Society of America, received a United States Senate Certificate of Special Recognition for her time as a NOAA Teacher at Sea during the 2014 field season, and has been named one of 100 women presented with the INSIGHT Into Diversity 2015 Inspiring Women in STEM Award.

Environmental Literacy Indicator Tool (ELIT) survey

PA Department of Education

From David Bauman, posted to the Science Learning Community Portal  --  On June 16, 2014, Pennsylvania’s governor Tom Corbett signed the Chesapeake Bay Watershed Agreement. In an effort to support this agreement, Pennsylvania is one of the six states completing the Environmental Literacy Indicator Tool (ELIT). In Pennsylvania, we plan on using the survey for the entire state. The results of this survey will provide baseline information regarding the state of environmental literacy in Pennsylvania’s schools and help to plan for the future.
