Students analyze conceptual, mathematical, and physical models of atoms. This unit also includes an overview of protons, neutrons, and electrons, as well as a periodic table of elements.
In this segment, the students learn about different models of the atom, including Dalton’s model, Thomson’s model, Rutherford’s model, and the Bohr model.
The periodic table is the focus of this segment. The students explore periodic trends as well as atomic number and average atomic mass.
In this segment, students build models of atoms as they learn about characteristics of electrons. They also explore how quantum levels affect fireworks by performing a flame test.
Students explore the relationship between the properties of an atom and its location on the periodic table as well as about effective nuclear charge and electronegativity.
In this segment, the students make predictions about electronegativity and atomic radius across periods and columns.
This segment examines ionization energy and explains the process for writing the electron configuration of any element.
The students learn to make electron configurations in this segment. Sublevels and orbitals are also discussed.
During this segment, special guest Mark Angeli explains the role of pyrotechnics in the making of fireworks.
We pay a visit to the CSX REDI Center in midtown Atlanta, where we talk with the fine folks of CSX about their 3,000 employees scattered around the state. REDI is the acronym for Railroad Education and Development Institute. That’s where most CSX employees come to learn about what it takes to work on the railroad, which also makes it a great place for us to learn more about CSX jobs.
The University of Georgia's College of Agricultural and Environmental Sciences invites us on a tour of its Mountain Research and Education Center, where we interview Dr. Wayne Hanna, one of the foremost turf growers in the world! He’s grown grass for sports complexes as far away as the World Cup Soccer Tournament in South Africa, and as close to home as UGA’s own athletic fields. Teachable Moments center around agriculture, including photosynthesis, the nitrogen cycle, and more.
In this unit, students learn about kinetics, which is the study of factors that affect the rate of chemical reactions. Students also investigate collision theory and the five components of kinetic molecular theory in gas.
