The students review the results of the smog experiment, analyze the data, and draw conclusions. The teacher asks them to create models based on what they learned about temperature and equilibrium.
In the last segment of unit 10, our students show their completed models and discuss how temperatures affects equilibrium. Deanna Oser, Program Manager at the Georgia Department of Natural Resources, joins our host to discuss how they monitor air quality.
Our host explains that nuclear chemistry is what happens in the nucleus of an atom. This segment also covers the nature of radioactivity and the release of energy as it occurs.
This segment explains how nuclear fission creates new elements. Students also learn about the characteristics of the three particles that result from nuclear decay, alpha, beta, and gamma radiation, and the energy derived from nuclear fission.
Students review results from nuclear decay experiments and learn how the law of the conservation of matter applies to nuclear chemistry. Students also learn what a half-life is, how it can be used to determine the age of a fossil, and how to solve a half-life problem.
In the final segment of this unit, students choose assignments in nuclear chemistry that reflect their learning styles and interests. We also visit an isotope laboratory at Georgia Power to see real world scientists at work as they measure levels of radiation in the environment.
Our host recaps the content in unit 1, " Science and Engineering Practices," which introduces students to using models, analyzing and interpreting data, computational thinking, constructing explanations, and more.
We recap Unit 2," Introduction to Matter," in which we covered crosscutting concepts that are used by scientists around the world and looked at the chemical and physical properties of matter.
Segment C reviews the information covered in Unit 3, "Atomic Structure." Students looked at models of atoms, discussed the Periodic Table, and heard from a fireworks expert who explained how chemistry is behind the variety of colors of a fireworks display.
In this segment, we review Unit 4, "Chemical Bonds." The unit covered the importance of evidence-based science and looked at both intra-molecular bonds that hold atoms together and intermolecular bonds, which exist between one molecule and another.
We see how students learned to recognize the signs of chemical change in this recap of Unit 5, "Chemical Reactions." The unit also covered the Law of the Conservation of Matter, and students balanced chemical equations and learned to draw models representing those equations.
In this recap of Unit 6, “Stoichiometry,” our host reviews what students learned about using dimensional analysis to solve stoichiometric problems. Students performed calculations and also learned about limiting and excess reactants using s’mores and launching miniature rockets in our lab.
This segment reviews Unit 7, "Solutions, Acids and Bases." The students saw how solvents dissolve solutes and how the rate of dissolution can be changed. They measured the concentration of solutions by molarity, mass percent, and molality.
Our host recaps Unit 8, "Chemical Thermodynamics.” The unit covered the three laws of thermodynamics and introduced students to thermochemistry. Total Bond Energy was covered, as well as specific heat capacity.
