Dedicated Outdoor Air Systems
Engineers at Pennsylvania State University have devised an air conditioning system that is more efficient than current standards and is highly resistant to dangerous airborne microbes such as anthrax. Because the Dedicated Outdoor Air System (DOAS) does not use recirculated air, a letter contaminated with anthrax would not spread throughout the building. A detailed technical overview of the concept is given on the DOAS home page, as well as an assessment of its benefits over traditional air cond

The Warming World: Designing for Climate Change
A workshop held in January 2003 attempted to ascertain how engineers and scientists need to change their practices to account for global warming. Road and bridge damage caused by "increased sediment loads in streams, catastrophic landslides, snow avalanches, and riverside flooding" necessitates a reevaluation of engineering design methods. Eight presentations from the workshop are given in slide form on this Web site. An executive summary is also provided, which outlines some of the proposed cha

Global Ups and Downs, Changing Sea Level
This unitfocuses on the concept that changes in sea level have occurred in the past, are occurring now, and will continue to occur. The unit provides an inquiry-based exploration of the lines of evidence for periodic melting of ice and resulting sea level rise: glacial evidence, geologic evidence, fossil evidence, and isotopic evidence. Students learn about the worldwide effects of sea level changes in the past and then use a study on topography and sea level to demonstrate their understanding o

What Did T. rex Taste Like?
This computer activity is an introduction to cladistics, which organizes living things by common ancestry and evolutionary relationships, enabling us to better understand life's present diversity and evolutionary history. The predictive power of cladistics can be used to answer questions that cannot be answered by observation of a living organism, such as What did dinosaurs taste like? This site presents a simplified version of the process used to generate cladistic analyses. A teacher's section

A Change in Seasons : Increasing Student Observation Skills
The ability to accurately observe and notice small details is a skill important to scientists. To help students develop this skill, have them record and share observations, successively focusing in on smaller, more precise details. When students observe changes in the seasons, they can extend their science knowledge by carefully noting changes in color, shape, and patterns in vegetation, asking questions, and making predictions.

2.1 Introduction
This unit is concerned with macroevolution – the patterns and processes of evolution above the species level. A crucial consideration in macroevolutionary studies is that of the evolutionary relationships (phylogeny) of the organisms in question. The unit begins with an introduction to the scope of macroevolutionary studies and illustrates methods of reconstructing phylogeny, from both morphological and molecular data.
