9:00 am Registration, Coffee and Refreshments – sponsored by Clark University Admissions
9:30 am Prof. David Thurlow: Exploring proteins and DNA at the National Center for Biotechnology Information (NCBI)
In the past decade, there has been an explosion in our understanding of proteins and DNA, essential biomolecules found in all living systems. Sequences and three dimensional structures are available free of charge at the NCBI website. We will explore genes, chromosomes, introns, exons, sequence alignments, phylogenetic trees, DNA helices, ribozymes, riboswitches, protein-ligand binding sites, enzyme active sites, and much, much more.
10:30 am Prof. Mark Turnbull: Demonstrating equilibrium with Co(II) salts and other demos
The equilibrium between the [Co(H2O)6]2+ cation (pink) and its anionic counterpart [CoCl4]2- provides a simple and visual way to illustrate equilibrium and LaChatelier’s Principle. Principles of adding/removing starting materials/products can be easily shown along with the effect of temperature on equilibrium. Participants will go through the laboratory exercise to illustrate these points. Time permitting, we’ll also generate a couple of explosions.
11:20 am Break
11:40 am Prof. Sergio Granados-Focil: Chemical processes within polymers and use of everyday polymers as teaching tools
Polymeric materials are everywhere and are used in a wide variety of every day applications. Some simple polymer synthesis experiments and polymer modification experiments will be presented. These demos can be used to illustrate fundamental concepts, such as stoichiometry, bonding, solubility, entropy, etc.
12:30 pm Light lunch followed by NEACT Board meeting
