  Friday  12/11  review book questions due Monday for both topic 3 and 4 as the unit test is Tuesday or Wednesday..depending on the amount of review needed 

Science 6

Monday: 12/14  Why Do We Measure Size worksheet and conclusion/graph due on Wed.  The entire lab for Jelly Side Up is due Wed.! 

Wednesday: 12/16    Finish completing the review sheet  for the unit test on Tuesday on experimental design. All students can use the info onthe review sheet to take the test… but it needs to be completely filled in!

New research results surprise everyone on the potential of this well-known Devonian black shale.

Super Giant Field in the Appalachians?
A few years ago every geologist involved in Appalachian Basin oil and gas knew about the Devonian black shale called the Marcellus. Its black color made it easy to spot in the field and its slightly radioactive signature made it a very easy pick on a geophysical well log.

However, very few of these geologists were excited about the Marcellus Shale as a major source of natural gas. Wells drilled through it produced some gas but rarely in enormous quantity. Few if any in the natural gas industry suspected that the Marcellus might soon be a major contributor to the natural gas supply of the United States – large enough to be spoken of as a “super giant” gas field.

In this topic of study we will be looking at the processes that shape Earth’s surface. Observe the surroundings outside your home (yard and street).  What evidence do you see of weathering, erosion and deposition. How would climate change and global warming effect these processes in New York? Give one example for a specific landscape mentioned in your ESRT.

Construction workers digging at ground zero have uncovered a 40-foot pothole and other features carved by glaciers about 20,000 years ago.

Unearthing these glacial features has been critical in preparing the foundation for Tower 4 of the new World Trade Center, being built by Silverstein Properties at the southeast corner of the site. Engineers need a clear understanding of the contours of the rock. Read the rest of this entry »

This unit of study involves learning about maps. Different map projections of the world and topographic maps are both models for Earth.  Make a list of some of the models people use in their daily life. Include physical models, mathematical models, and mental models. List at least two examples of each and make sure you tell what it represents, why it is used instead of the real object or concept, and if it is a scale model.

You should use different examples than those previously posted.

Due: Friday morning, Sept. 26.

The first topic of study involves investigating what Earth science is really all about, and what subtopics Earth science encompasses. We learned that Earth has “spheres”.

What effect do you have on Earth systems? Which sphere do you live on and what are some ways you change the spheres? Are these behaviors beneficial or detrimental to Earth?

Write a response to this post that includes all parts of the question. Read the previous posts and tell if you agree or disagree with previous student responses.

It’s relatively easy to track the history of animal life, as animals are often macroscopic and build things like shells and bone. But about 70 percent of the history of life on earth appears to have taken place before animals were on the scene, meaning fossils can only tell a partial story. At the recent evolution symposium hosted by Rockefeller University, Roger Buick spoke about trying to reconstruct the history of the time when Bacteria and Archaea ruled the earth. Separately, Andrew Knoll discussed his attempts to use geology to try to understand the conditions that allowed animal life to bring an end to that era.

The Phoenix lander has sent back new pictures from the arctic circle of Mars, showing for the first time the spot where it will dig through the Red Planet’s dusty surface looking for water and assess conditions for life.

It landed at the edge of a massive crater so large that it could fit 11 Wembley stadiums inside it. The half-ton craft – the size of a small pick-up truck – will scoop up samples of frozen soil from near the six-mile wide crater for analysis by its instruments. Read the rest of this entry »

Our long-term goals are to determine whether life ever arose on Mars, to examine climate, characterise geology and prepare for human exploration.

Mars is a cold desert planet with no liquid water on its surface. However, discoveries made by the Mars Odyssey Orbiter in 2002 showed large amounts of subsurface water ice. The Phoenix Lander targets this region. Read the rest of this entry »

FAIRBANKS, Alaska, April 1 (UPI) – The U.S. space agency says the most extensive research project ever conducted to investigate the Arctic’s lower atmosphere begins this week.

The three-week mission is designed to help scientists identify how air pollution contributes to climate changes in the Arctic. Read the rest of this entry »
