Do Crayfish Change Color If Their Environment Changes? A Guided Inquiry Lab for 7th grade Life Science

Background: There is anecdotal evidence from bass fisherman that crayfish are able to change color depending on their surroundings. A (cursory) literature review of this phenomenon showed that no formal research has been done in this area. Students had an additional informal lesson about research funding (or lack thereof) because of this finding.

Students designed and conducted a controlled experiment to see the effect of changing environment color on crayfish color.

ADI was used to quantify a color change.

The First Ten Months Of Investigation Of Gravity Waves And Temperature Variability Over The Andes., Jonathan R. Pugmire, Neal Criddle, Michael J. Taylor, Dominique Pautet, Yucheng Zhao May 2010

The First Ten Months Of Investigation Of Gravity Waves And Temperature Variability Over The Andes., Jonathan R. Pugmire, Neal Criddle, Michael J. Taylor, Dominique Pautet, Yucheng Zhao

Jonathan Pugmire

The Andes region is an excellent natural laboratory for investigating gravity wave influences on the Upper Mesospheric and Lower Thermospheric (MLT) dynamics: during the summer months the dominant gravity waves result from deep convection arising from severe thunderstorms over the continent to the east. In winter this convective activity is expected to be replaced by strong orographic forcing due to intense prevailing zonal winds blowing eastward from the Pacific Ocean and suddenly encountering the towering Andes mountain range (6000m). This creates large amplitude mountain waves that have been measured well into the stratosphere and most recently penetration occasionally into the ...

Intra-Annual Comparison Of Mesospheric Gravity Waves Over Halley And Rothera Stations, Antarctica., Jonathan R. Pugmire, Mike J. Taylor, Kim Nielsen May 2009

Intra-Annual Comparison Of Mesospheric Gravity Waves Over Halley And Rothera Stations, Antarctica., Jonathan R. Pugmire, Mike J. Taylor, Kim Nielsen

Jonathan Pugmire

As part of a collaborative program between British Antarctic Survey and Utah State University, we present an intra-annual study of short-period, mesospheric gravity wave events observed over Antarctica in the near infrared OH emission. The measurements were made using an all-sky airglow imager operated at either Halley Station on the Brunt Ice Shelf, or Rothera Station, situated on the Antarctic Peninsula. A total of six austral winter seasons have been analyzed (2000-2006). This study comprises the first detailed winter seasonal investigation of short-period mesospheric gravity waves at high-Antarctic latitudes. Distributions of their observed wave parameters were found to be similar ...
