CHS students represented our school well at the Region Science Fair. Caroline Hendricks finished first in her category and will be continuing on to compete at the Georgia Science and Engineering Fair in Athens on April 1st and 2nd. Her project was titled "Symbiotic Nitrogen Fixation in Small and Large Partridge Pea." Maria Roman and Michael Morgan both finished first in their categories, Nicole Morris finished second in her category, and Darby Gainey finished third in her category. Congratulations to all the students who represented CHS at the Region Science Fair.
Mrs. Bradford-Hunt's Pre-AP Chemistry students used yarn to "discover" molecular geometries for different types of covalent compounds. They arrange the yarn in such a way that each string represents a region of high electron density and they have to arrange them so they are as far apart as they can get. It allows them to see the shapes and determine how their arrangement will look in space.
Mr. Shirley's Human Anatomy and Physiology students completed a lab where they had to use materials to create a 3D model of the human digestive system. Students had to put the organs (materials) in the correct location along the Gastrointestinal tract, as well as label the organs and list the functions of each organ. Students worked on this projects in groups of 2-3 students. Enjoy the pictures below.
Biology students discover a mystery animal with the only clue being 6 sections of DNA. They had to complete protein synthesis, creating mRNA from DNA and then connecting a series of amino acids to form a protein. These proteins represented traits such as hairy, 4-legged, feline.
IB students gather mud from local Buffalo Creek to create Winogradsky columns. They packed layers of mud with newspaper as a carbon source and egg yolks as sulfer. In the next few weeks layers of different bacteria will make themselves visible as various colors. The ecosystem in a box will be studied for its separation of aerobic vs. anaerobic autotrophs.
