Even when our air looks clear, it contains billions of nano- to micron-scale solid particles and liquid droplets known as aerosols. Because they provide one of the greatest uncertainties in understanding natural and man-made changes in climate, aerosols are the subject of a wide spectrum of current scientific research. Aerosols are also a topic of intense interest among scientists exploring engineering approaches to correcting atmospheric and climate problems. In inquiry-based, hands-on activities, students will use satellite imagery and data, simulated cores, and probeware to examine the role of aerosols in the ocean and atmospheric processes, climate trends, ecosystem health, desertification, watershed hydrology, and geoengineering research.
Lesson Requirement: MSiC instructor will need classroom access to the Internet for use of Google Earth and other Web resources.

How do the letters in a Punnett square relate to the inheritance of a physical trait? How are alleles translated into proteins? What does it mean for an allele to be “recessive” or “dominant”? Can environmental experiences be “passed down” to offspring? This lesson addresses these and other questions. The fundamental version of this lesson teaches how an allele is manifested as a genetic trait via transcription and translation. In the advanced version, topics move into the realm of histones, cell receptors, and epigenetics. It is quite possible that what you are may be influenced by your grandparents’ experiences.

Foraminifera, nicknamed “forams,” are single-celled organisms that have inhabited earth’s marine and brackish waters for at least 550 million years, with thousands of species in both the fossil record and modern waters. Although forams are small, their importance to science is enormous! Because of their diversity, abundance, and sensitivity to environmental conditions, forams are used in petroleum exploration, stratigraphy, archaeology, coastal and estuarine ecology, and paleoceanography. They are especially important indicators of changing conditions in oceans and estuaries, and of local and global climate change. Using hands-on activities and 21st-century technology, students will explore how forams help reconstruct ancient ocean conditions and track human impacts on the Chesapeake Bay.

Nanoscale Processes in Hemoglobin Function (Biology, AP Biology, IB Biology)
Standards of Learning: 2010 Biology (BIO.1, BIO.2, BIO.5); Electives: AP Biology, IB Biology
The properties of hemoglobin emerge from its quaternary structure; slight modifications in that structure can compromise its function, resulting in diseases such as sickle cell anemia. In this lesson designed for students in Honors, AP, and IB Biology, students will use the free software program Cn3D to examine the molecular interactions that determine the level of protein structure. By manipulating 3D computer models of normal vs. sickle cell hemoglobin, students can see how a point mutation changes a hydrophilic R-group into a hydrophobic one, resulting in the oxygen-bonding deficiencies characteristic of sickle cell anemia. Includes an overview of hemoglobin’s cooperative binding that gives rise to the oxygen dissociation curve.
